Open Innovation: The New Imperative For Creating and Profiting From Technology
Companies that don’t innovate die, but meta-innovation (innovating how to innovate) is becoming increasingly the center of the attention. In his book, Chesbrough describes two different paradigms for technological innovation: one internal (described as ‘classic’ or ‘closed’) and one external. Chesbrough’s thesis is that the internal paradigm is now being rendered obsolete by the external one. The internal paradigm is based on research and development done in-house: companies fund their research labs, which produce intellectual property, which is developed and capitalized by the company and can inject further funding in the research process. Chesbrough indicates two major factors eroding this paradigm: the growing mobility of skilled people; and the growing presence of Venture Capital. The combination of these two factors increases the permeability of the firm, and allows ideas and intellectual property to escape the company’s boundaries. Chesbrough outlines how these erosions factors impacted Xerox in its PARC research center. He shows how the company failed to capitalize on several of the groundbreaking innovations that originated in those labs and were made profitable elsewhere. The external innovation paradigm (that Chesbrough names ‘open’ in contrast with the ‘closed’ one) is designed to accept and profit from those eroding factors and is based on the idea that companies should develop a knowledge-creation and intellectual property management strategy which assumes that R&D involves an effective synthesis of internal research and development and intellectual property derived from the environment. Chesbrough suggests that if firms are working in a fertile innovation environment, innovation will flourish, and that it is much cheaper and safer for firms to simply shop for the ideas that they consider most promising, which supplement their internal development efforts. The purchasing company must continue the development in-house, refine and eventually integrate the new product with existing products or services. He shows how Intel and Cisco managed innovation at the pace required by the market by investing as venture capitalists in the open market and further refining the technologies that those start-ups were able to incubate, or simply by licensing intellectual property that originated elsewhere. The increased effectiveness of the external innovation paradigm is not only due to the cited erosion factors, but Chesbrough describes how research and development follow different rules and while the first resembles the game of poker (high risk, fast pace, low strategy), the second resembles the game of chess (lower risk, slower pace, higher strategy). He argues that while firms normally focus on the second part, it is very hard for them to play such a different and risky game. The ability to know when to stop the funding and fold or continue the capital injection is something that Venture Capital firms have learned to master, while regular firms struggle with it. Chesbrough suggests that firms should focus on their strategic game of intellectual property acquisition to reduce their capital risks and research costs while venture capital firms (or external smaller firms) play the risky game of research.

Social networks for innovation and new product development
In this article we first provide a brief introduction into social network analysis, focusing on the measures and approaches that are used in the empirical contributions in this special issue. Second, we discuss the role of social networks in new product development. Social networks are inherently multilevel; we consider four “levels”: networks inside a firm, networks that cross firm boundaries, networks between firms, and networks that reside outside of the firm. Third, we discuss these four levels and highlight some of the extant research. We summarize and position the eight papers in this special issue along these four levels. Together, we argue, these papers provide an interesting coverage of this burgeoning field.

The paradox of openness: Appropriability, external search and collaboration
To innovate, firms often need to draw from, and collaborate with, a large number of actors from outside their organization. At the same time, firms need also to be focused on capturing the returns from their innovative ideas. This gives rise to a paradox of openness—the creation of innovations often requires openness, but the commercialization of innovations requires protection. Based on econometric analysis of data from a UK innovation survey, we find a concave relationship between firms’ breadth of external search and formal collaboration for innovation, and the strength of the firms’ appropriability strategies. We show that this concave relationship is stronger for breadth of formal collaboration than for external search. There is also partial evidence suggesting that the relationship is less pronounced for both external search and formal collaboration if firms do not draw ideas from or collaborate with competitors. We explore the implications of these findings for the literature on open innovation and innovation strategy.

Geography, Networks, and Knowledge Flow
Knowledge---which is closely linked to firm innovativeness---is accessed across organizational boundaries and geographic space via networks operating at different levels of analysis. However, we know tantalizingly little about the comparative influence of geography on knowledge flow across organizational boundaries over different types of ties, despite warnings that research needs to account for the geographic context of ties to fully understand causal relationships. Using a combination of primary and secondary data on 77 Canadian mutual fund companies, we find that institutional-level ties are valuable in knowledge transmission only when such ties are geographically proximate. Organization-level ties fail to act as transmitters of knowledge, regardless of geographic location. Interestingly, we find that geographically distant individual-level friendship ties are superior conduits for knowledge flow, which suggests they span “geographic holes.”

How Exactly Do Network Relationships Pay Off? The Effects of Network Size and Relationship Quality on Access to Start–Up Resources
Entrepreneurs are expected to profit from network relationships. Research addressing the link between entrepreneurs’ network characteristics and their performance, however, has so far produced inconclusive results. In an attempt to explain these inconsistencies, we investigate the resource returns connected to network size and relationship quality. Based on a sample of 379 nascent entrepreneurs, we find that increasing network size and relationship quality results in diminishing marginal returns in terms of access to financial capital, knowledge and information, and additional business contacts. Additionally, we observe that the returns vary strongly by resource type.

Signals across multiple networks: : how venture capital and alliance networks affect interorganizational collaboration.
In this article, we examine the contingent effects of signals generated by different types of networks on new ventures' formation of future strategic alliances. We argue that the signaling value of a given tie in reducing adverse selection is more pronounced when another type of tie is lacking. In particular, we suggest that signals associated with (i) a new venture's affiliations with venture capitalists (VCs) that have prominent positions in syndicate networks and (ii) a new venture's prominent position in alliance networks resulting from previous alliances offer redundant benefits. As a result, the positive effect of VC prominence in determining a new venture's future alliance formation diminishes as the new venture's prominence in alliance networks increases. Evidence from biotech alliances between new ventures and established companies provides support for our theory. [ABSTRACT FROM AUTHOR]

Network embeddedness and new product development in the biopharmaceutical industry: The moderating role of open innovation flow
This paper explores the role of centrality and structural holes positions on the likelihood to develop new products and the moderating role of the open innovation flow, a measure of the net knowledge flow crossing the firm’s boundaries, on the aforementioned relation. We argue that network positions provide the information content to the firm, whilst open innovation flow describes how the firm uses such content, thus the combination of these two concepts has a significant impact on new product development. We test the theoretical framework on a large sample of 544 public companies and data from 1758 agreements among 1890 bio-pharmaceutical firms through the period 2006–2010. Our results show that being centrally located in the network positively affects the new product development process, while having a structural holes position has no effect on the aforementioned performance. However, the interaction of the two network positions with the open innovation flow has a positive impact on the likelihood to develop new products.

The Two Faces of Control: Network Closure and Individual Performance among Knowledge Workers
This paper argues that the effect of dense social ties, or network closure, on a knowledge worker's performance depends on the predominant role this worker plays with his or her exchange partners in the relationships affected by that closure. Using data on informal exchanges among investment bankers in the equities division of a large financial services firm operating in Europe, Asia-Pacific, Africa, and the Americas in 2001, we find that network closure in relationships in which the banker acts as an acquirer of information increases his or her performance, whereas closure in relationships in which the banker acts as a provider of information decreases it. We also find that these effects are moderated by the bankers' ability to employ alternative means (such as formal authority) to induce the cooperation of exchange partners in their acquirer role, as well as by the extent to which the bankers can benefit from being free from the control of exchange partners in their provider role. Our findings highlight the two sides of the normative control associated with network closure: control benefits people when they need to induce exchange partners to behave according to their preferences, but it hurts them when it forces them to behave according to the preferences of those partners.

Regions Matter: How Localized Social Capital Affects Innovation and External Knowledge Acquisition
To introduce new products, firms often use knowledge from other organizations. Drawing on social capital theory and the relational view of the firm, we argue that geographically localized social capital affects a firm's ability to innovate through various external channels. Combining data on social capital at the regional level, with a large-scale data set of the innovative activities of a representative sample of 2,413 Italian manufacturing firms from 21 regions, and controlling for a large set of firm and regional characteristics, we find that being located in a region characterized by a high level of social capital leads to a higher propensity to innovate. We find also that being located in an area characterized by a high degree of localized social capital is complementary to firms' investments in internal research and development (R&D) and that such a location positively moderates the effectiveness of externally acquired R&D on the propensity to innovate.

Bilateral Collaboration and the Emergence of Innovation Networks
In this paper, we model the formation of innovation networks as they emerge from bilateral decisions. In contrast to much of the literature, here firms only consider knowledge production, and not network issues, when deciding on partners. Thus, we focus attention on the effects of the knowledge and information regime on network formation. The effectiveness of a bilateral collaboration is determined by cognitive, relational, and structural embeddedness. Innovation results from the recombination of knowledge held by the partners to the collaboration, and its success is determined in part by the extent to which firms' knowledge complement each other. Previous collaborations (relational embeddedness) increase the probability of a successful collaboration, as does information gained from common third parties (structural embeddedness). Repeated alliance formation creates a network. Two features are central to the innovation process: how firms pool their knowledge resources, and how firms derive information about potential partners. When innovation is decomposable into separate subtasks, networks tend to be dense; when structural embeddedness is important, networks become cliquish. For some regions in this parameter space, small worlds emerge.

Internet entrepreneurship: Social capital, human capital, and performance of Internet ventures in China
Abstract This article examines the interaction effects of social capital and human capital (experience) of entrepreneurs on the performance of Internet ventures. The empirical data are composed of the longitudinal surveys of 94 Internet ventures in Beijing, China. The study found that the interaction of social capital and Western experience of entrepreneurs has a positive effect on the survival likelihood of Internet firms whereas the interaction of social capital and startup experience of entrepreneurs has a negative effect on firm performance.

The duality of collaboration : Inducements and opportunities in the formation of interfirm linkages
I argue that the linkage-formation propensity of firms is explained by simultaneously examining both inducement and opportunity factors. Drawing upon resource-based and social network theory literatures I identify three forms of accumulated capital—technical, commercial, and social—that can affect a firm’s inducements and opportunities to form linkages. Firms possessing these capital stocks enjoy advantages in linkages formation. However, firms lacking these accumulated resources can still form linkages if they generate a radical technological breakthrough. Thus, I identify paths to linkage formation for leading as well as peripheral firms. I test these arguments with longitudinal data on technical collaborative linkages in the global chemicals industry. Copyright © 2000 John Wiley & Sons, Ltd.

Structural Holes and Good Ideas1
This article outlines the mechanism by which brokerage provides social capital. Opinion and behavior are more homogeneous within than between groups, so people connected across groups are more familiar with alternative ways of thinking and behaving. Brokerage across the structural holes between groups provides a vision of options otherwise unseen, which is the mechanism by which brokerage becomes social capital. I review evidence consistent with the hypothesis, then look at the networks around managers in a large American electronics company. The organization is rife with structural holes, and brokerage has its expected correlates. Compensation, positive performance evaluations, promotions, and good ideas are disproportionately in the hands of people whose networks span structural holes. The between‐group brokers are more likely to express ideas, less likely to have ideas dismissed, and more likely to have ideas evaluated as valuable. I close with implications for creativity and structural change.

Benefiting from network position: firm capabilities, structural holes, and performance
While strategy scholars primarily focus on internal firm capabilities and network scholars typically examine network structure, we posit that firms with superior network structures may be better able to exploit their internal capabilities and thus enhance their performance. We examine how innovative capabilities—both those of focal firms and those they access through their networks—influence the performance of Canadian mutual fund companies. We find that a firm's innovative capabilities and its network structure both enhance firm performance, while the innovativeness of its contacts does not do so directly. Innovative firms that also bridge structural holes get a further performance boost, suggesting that firms need to develop network‐enabled capabilities—capabilities accruing to innovative firms that bridge structural holes.

Network Closure or Structural Hole? The Conditioning Effects of Network–Level Social Capital on Innovation Performance
This study contributes to the bonding–bridging debate in the social capital literature by examining the conditioning effects of collective social capital. Data generated from simulation reveals that network density, a measure of network–level social capital, negatively moderates the impacts of firm–level social capitals, measured separately by degree centrality and structural hole, on a firm's innovation performance. Specifically, in low–density networks, degree centrality and structural holes are complementary at enhancing innovation performance. In high–density networks, the positive impact of degree centrality weakens and structural holes turn out to be detrimental. The findings not only advance our understanding of the cross–level dynamics of social capital, but also provide a possible explanation for the mixed empirical results found in previous studies.

Social Capital and Entrepreneurial Performance in Russia: A Longitudinal Study
Drawing on the social embeddedness perspective, this article examines the impact of entrepreneurs' social capital on their firm performance in post-Soviet Russia. Based on face-to-face interviews with 75 Russian entrepreneurs in 1995 and follow-up interviews in 1999, the study examines effects of structural embeddedness, relational embeddedness and resource embeddedness on firm performance. The main finding is that relational embeddedness and resource embeddedness have direct positive impacts on firm performance, whereas structural embeddedness has no direct impacts on performance.

Structural vs. relational embeddedness: social capital and managerial performance
This paper examines the impact of managers' social capital on managerial performance. Two dimensions of social capital are compared—the structural embeddedness (i.e., configuration) of a manager's network of work relations and the relational embeddedness (i.e., quality) of those relations. Based on a sample of 120 product and sales managers in a Fortune 100 pharmaceutical firm, this paper presents evidence indicating that both elements of social capital influence managerial performance, although in distinct ways: structural embeddedness plays a stronger role in explaining more routine, execution‐oriented tasks (managerial sales performance), whereas relational embeddedness plays a stronger role in explaining new, innovation‐oriented tasks (managerial performance in product and process innovation). This research considers resource exchanges within firms as key to value creating behaviors and contributes a deeper understanding of how social capital influences productive resource exchanges.

The Genesis and Dynamics of Organizational Networks
An extensive body of knowledge exists on network outcomes and on how network structures may contribute to the creation of outcomes at different levels of analysis, but less attention has been paid to understanding how and why organizational networks emerge, evolve, and change. Improved understanding of network dynamics is important for several reasons, perhaps the most critical being that the understanding of network outcomes is only partial without an appreciation of the genesis of the network structures that resulted in such outcomes. To provide a context for the papers in this special issue, and with the broader goal of furthering network dynamics research, we present a framework that begins by discussing the meaning and role of network dynamics and goes on to identify the drivers and key dimensions of network change as well as the role of time in this process. We conclude with theoretical and methodological issues that researchers need to address in this domain.

The formation of economic networks: a proximity approach
The notion of proximity is increasing in popularity in economic and geographic literature, and is now commonly used by scholars in regional science and spatial economics. Few academic works, however, have explored the link between regional development and proximity relations. This comprehensive book redresses the balance with its assessment of the role of, and obstacles caused by, proximity relations in regional development processes.

Proximity and power in collaborative innovation projects
ABSTRACT Proximity and power in collaborative innovation projects. Regional Studies. The proximity literature has so far paid little attention to power relations in collaborative innovation projects. This paper draws on contributions from international business to examine if power constellations between collaborators in innovation projects influence the effects of proximity. An analysis of two cases of collaborations between headquarters and subsidiaries of multinational companies highlights that specific power constellations indeed influence the effects of proximity. While some forms of proximity allow subsidiary-specific capabilities to diffuse throughout the organization and pose a threat to the powerful subsidiary, the weaker subsidiary considers proximity as a possibility to learn from the headquarters.

Knowledge and Information Networks in an Italian Wine Cluster
The aim of this article is to analyse the nature and extent of knowledge and information networks in an Italian wine cluster. Moreover, the relation between firms’ characteristics and the knowledge network structure is also explored. The empirical findings show that knowledge is unevenly distributed in clusters and that networks of knowledge and information differ a great deal in terms of their structure. In fact, knowledge flows are restricted to a tightly connected community of local producers, differing in terms of knowledge assets, innovation behaviour and overall economic performance with respect to the rest of the firms in the cluster.

Network Structure and Knowledge Transfer: The Effects of Cohesion and Range
This research considers how different features of informal networks affect knowledge transfer. As a complement to previous research that has emphasized the dyadic tie strength component of informal networks, we focus on how network structure influences the knowledge transfer process. We propose that social cohesion around a relationship affects the willingness and motivation of individuals to invest time, energy, and effort in sharing knowledge with others. We further argue that the network range, ties to different knowledge pools, increases a person's ability to convey complex ideas to heterogeneous audiences. We also examine explanations for knowledge transfer based on absorptive capacity, which emphasizes the role of common knowledge, and relational embeddedness, which stresses the importance of tie strength. We investigate the network effect on knowledge transfer using data from a contract R&D firm. The results indicate that both social cohesion and network range ease knowledge transfer, over and above the effect for the strength of the tie between two people. We discuss the implications of these findings for research on effective knowledge transfer, social capital, and information diffusion.

A social network perspective on turnover intentions: The role of distributive justice and social support
Organizations are increasingly concerned about retaining human talent, particularly within knowledge-based industries where turnover is expensive. Our study employs a social network perspective to explore the influence of employees' formal and informal workplace relationships on their turnover intentions. We do this in a life sciences organization experiencing employee turnover at over twice the rate of the industry average. Drawing on extant work on the effects of distributive justice at work, we argue that employees who are heavily sought out for advice see themselves as being under-rewarded for the time and effort that goes into providing advice, thus increasing turnover intentions. Additionally, we argue that employees see the ability to seek out advice as a form of social support that embeds them into the organization and decreases intention to quit. By exploring the network positions of individuals in the workflow and advice networks, we demonstrate that when employees are either providing advice to someone they are obligated to work with or are able to seek out advice from others who are not required to work with them, the relationship with turnover intentions is most intense. We conclude by discussing contributions to the theory and practice of human resource management. © 2013 Wiley Periodicals, Inc.

Social Capital in the Creation of Human Capital
In this paper, the concept of social capital is introduced and illustrated, its forms are described, the social structural conditions under which it arises are examined, and it is used in an analysis of dropouts from high school. Use of the concept of social capital is part of a general theoretical strategy discussed in the paper: taking rational action as a starting point but rejecting the extreme individualistic premises that often accompany it. The conception of social capital as a resource for action is one way of introducing social structure into the rational action paradigm. Three forms of social capital are examined: obligations and expectations, information channels, and social norms. The role of closure in the social structure in facilitating the first and third of these forms of social capital is described. An analysis of the effect of the lack of social capital available to high school sophomores on dropping out of school before graduation is carried out. The effect of social capital within the family and in the community outside the family is examined.

Strong ties, weak ties and islands: structural and cultural predictors of organizational innovation
How does the tendency of entrepreneurs to engage in innovation relate to their structural and cultural embeddedness? Using micro-data on entrepreneurial teams and the organizational innovations they attempt to develop, this article presents a predictive model of creative action to address this question. Capacity for creative action is seen to be a function of the ability of entrepreneurs to (i) obtain non-redundant information from their social networks; (ii) avoid pressures for conformity; and (iii) sustain trust in developing novel--and potentially profitable--innovations. Probit analyses of over 700 organizational startups suggest that these mechanisms exercise effects on innovation via the network ties and enculturation of entrepreneurs.

Domestic alliance networks and regional strategies of MNEs: A structural embeddedness perspective
We draw on a social network perspective to explain multinational enterprises’ (MNEs) propensity to distribute their operations unevenly across various regions of the world. We focus on how the positioning of MNEs in their domestic network of strategic alliances affects their geographic scope, i.e., whether they concentrate on their home region or expand beyond it. We theorize that embeddedness in alliance networks constitutes a double-edged sword to the geographic scope of MNEs. Strong embeddedness in domestic alliance networks drives the development of location-bound firm-specific advantages (FSAs), which may narrow down MNEs’ geographic scope. In contrast, moderate embeddedness leads to more non-location-bound FSAs, which reduce liability of foreignness, and hence motivate MNEs to widen their geographical scope. We thus predict a non-linear relationship between domestic alliance network embeddedness and MNE geographic scope. Furthermore, the impact of the domestic alliance network on MNE geographic scope hinges on the organizational ability to efficiently and effectively absorb resources stemming from the network. We test our hypotheses using FDI data from 302 US MNEs in the information and communication technology industry for the period of 2001–2008, and generally find robust support for the hypothesized relationships.RésuméNous nous appuyons sur une perspective du réseau social pour expliquer la propension des entreprises multinationales (EMN) à répartir inégalement leurs opérations dans les diverses régions du monde. Nous nous concentrons sur la façon dont le positionnement des entreprises multinationales, dans leur réseau domestique d’alliances stratégiques, impacte leur champ géographique ; c’est-à-dire, si elles se concentrent sur leur région d’origine ou si elles s’étendent au-delà. Nous faisons l’hypothèse que l’intégration dans les réseaux d’alliances constitue une épée à double tranchant concernant le champ géographique des entreprises multinationales. La forte intégration dans des réseaux d’alliances nationales conduit au développement d’avantages spécifiques de l’entreprise (ASE) liés à la localisation, ce qui peut limiter le champ géographique des entreprises multinationales. En revanche, une intégration modérée conduit à plus d’ASE non liés à la localisation, ce qui réduit les inconvénients de l’extranéité et motive ainsi les EMN à élargir leur champ géographique. Nous prévoyons donc une relation non-linéaire entre l’intégration au sein d’un réseau d’alliances nationales et le champ géographique des EMN. En outre, l’impact du réseau d’alliances domestiques sur le champ géographique des EMN repose sur la capacité organisationnelle à efficacement et utilement absorber les ressources découlant du réseau. Nous testons nos hypothèses à l’aide de données sur les investissements directs étrangers de 302 EMN américaines dans l’industrie des technologies de l’information et de la communication pour la période 2001‒2008 et nous constatons généralement une solide confirmation des relations hypothétiques envisagées.ResumenNos basamos en una perspectiva de redes sociales para explicar la propensión de las empresas multinacionales (EMN) a distribuir sus operaciones de manera desigual en varias regiones del mundo. Nos enfocamos en cómo el posicionamiento de las EMN en su red local de alianzas estratégicas afecta su alcance geográfico; es decir, si se concentran en su región de origen o se expanden más allá de esta. Teorizamos que la integración en redes de alianzas constituye una espada de doble filo para el alcance geográfico de las EMN. Una fuerte integración en redes de alianzas domésticas impulsa el desarrollo de las ventajas específicas de la empresa vinculadas a un lugar determinado, lo que puede estrechar el alcance geográfico de la EMN. En contraste, una integración moderada lleva a ventajas específicas de la empresa no vinculadas a un lugar determinado, lo cual reduce las desventajas de extranjería, y por ende motiva a las EMN a ampliar su alcance geográfico. Por ende, predecimos una relación no linear entre la integración en una red de alianza doméstica y el alcance geográfico de una EMN. Además, el impacto de la red de alianza doméstica en el alcance geográfico de la MNE se articula con la habilidad organizacional para absorber eficiente y efectivamente los recursos procedentes de la red. Nosotros pusimos a prueba nuestras hipótesis usando datos de IED de 302 EMN estadounidenses en la industria de las tecnologías de información y comunicación en el periodo 2001 al 2008, y en general encontramos un apoyo sólido paras las relaciones de las hipótesis.ResumoNós partimos de uma perspectiva de rede social para explicar a propensão de empresas multinacionais (MNEs) para distribuir suas operações de forma desigual em várias regiões do mundo. Nós nos concentramos em como o posicionamento das multinacionais em sua rede doméstica de alianças estratégicas afeta seu escopo geográfico; ou seja, se eles se concentram em sua região de origem ou se expandem para além da mesma. Nós teorizamos que a inserção nas redes de alianças constitui uma espada de dois gumes para o escopo geográfico das MNEs. A forte inserção nas redes de alianças domésticas impulsiona o desenvolvimento de vantagens específicas da empresa vinculadas à localização (FSAs), que podem restringir o escopo geográfico das MNEs. Em contrapartida, a inserção moderada leva a mais FSAs não vinculadas à localização, que reduzem a desvantagem de ser estrangeiro e, portanto, motivam as MNEs a ampliar seu escopo geográfico. Prevemos, assim, uma relação não-linear entre a inserção na rede de aliança doméstica e o escopo geográfico do MNE. Além disso, o impacto da rede de aliança doméstica no escopo geográfico da MNE depende da capacidade organizacional de absorver eficiente e efetivamente recursos provenientes da rede.

Knowledge Networks and Innovative Performance in an Industrial District: The Case of a Footwear District in the South of Italy
The traditional district literature tends to assume that: (1) the competitiveness of firms depends on external sources of knowledge; (2) all firms in a district benefit from knowledge externalities; (3) relying on external knowledge relationships necessarily means these are confined to the district area. Our case study of the Barletta footwear district in the South of Italy suggests otherwise. Based on social network analysis, we demonstrate that the local knowledge network is quite weak and unevenly distributed among the local firms. A strong local network position of a firm tended to increase their innovative performance, and so did their connectivity to extra‐local firms. So, it mattered being connected either locally or non‐locally: being co‐located was surely not enough. Having a high absorptive capacity seemed to raise only indirectly, through non‐local relationships, the innovative performance of firms.

The Selective Nature of Knowledge Networks in Clusters: Evidence from the Wine Industry
Most of the studies about industrial clusters and innovation stress the importance of firms' geographical proximity and their embeddedness in local business networks (BNs) as factors that positively affect their learning and innovation processes. More recently, scholars have started to claim that firm-specific characteristics should be considered to be central in the process of learning and innovation in clusters. This article contributes to this latter direction of research. It applies social network analysis to explore the structural properties of knowledge networks in three wine clusters in Italy and Chile. The results show that in spite of firms' geographical proximity and the pervasiveness of local BNs, innovation-related knowledge is diffused in clusters in a highly selective and uneven way. This pattern is found to be related to the heterogeneous and asymmetric distribution of firm knowledge bases in the clusters. Copyright 2007, Oxford University Press.

Knowledge Networks, Collaboration Networks, and Exploratory Innovation
Innovation in firms is doubly embedded: in a social network of collaborations between researchers, and in a knowledge network composed of linkages between knowledge elements. The two networks are decoupled. Their structural features are distinct and influence researchers' exploratory innovation differently. Using the patent data of a leading U.S. microprocessor manufacturer, we constructed the firm's collaboration and knowledge networks, and examined the effects of two structural features in the two networks--structural holes and degree centrality--on researchers' exploratory innovation. Our findings show that a researcher with knowledge elements rich in structural holes in the knowledge network tends to explore fewer new knowledge elements from outside the firm, while structural holes in the collaboration network increase exploratory innovation. The average degree centrality of a researcher's knowledge elements in the knowledge network has an inverted-U-shaped relationship with his or her exploratory innovation, while degree centrality in the collaboration network has a negative effect. This study suggests that knowledge and social networks influence where researchers search for discoveries

From birth through transition to maturation : the evolution of technology-based alliance networks
This article considers the evolution of interfirm networks within a context of technological change. More specifically, it studies the evolution of structural and positional embeddedness in a network of technology-based alliances when it moves from an early period of invention creation to a subsequent period of new product development and commercialization. Empirically, we study the evolution of technology-based alliance networks in the biopharmaceutical industry over a period of about 25 years, from 1975 until 1999. Examining interorganizational networks over such an extended time period allows us to move beyond more static approaches that have characterized most network studies until now, and consider network evolution along its various phases of birth, growth, and early maturation instead. Our findings indicate that the evolution of both structural and positional embeddedness does not follow the common idea of a path of linear progression, but instead strongly exhibits nonlinearity by resembling a sigmoid pattern. These findings have a number of implications. First, the break in the process of linear progression contrasts with the standing literature that (implicitly) assumes the informational and resource value of a network structure to remain constant over time or to evolve linearly from carrying low value to progressively higher value. Instead, our finding that the evolution of structural and positional embeddedness is nonlinear echoes the speculative idea, as expressed by Gulati and Garguilo, that network change may possibly be nonlinear when seen over the long run. A second implication concerns the validity of standing insights from the social network literature such as Coleman's theory of social capital and Burt's theory of structural holes. These theories may not apply to the extent that there are strong changes in environmental conditions like environmental uncertainty and/or munificence, such as during a transition phase as considered in this study.

Clusters, networks, and firm innovativeness
This paper extends current knowledge of industry clusters by disentangling the effects of networks from cluster (i.e., distinctly geographic) mechanisms on firm performance as well as by studying the influence of these different mechanisms on firms located inside and outside the industry cluster. It also highlights the importance of simultaneously modeling multiple networks which may differentially influence important firm outcomes. In the paper, I model the innovativeness of Canadian mutual fund companies as a function of their geographic location—inside or outside the industry cluster of Toronto—and of their centrality in networks of managerial and institutional ties. I find that locating in the industry cluster as well as centrality in the managerial tie network enhances firm innovation, while centrality in the institutional tie network does not.

A social network analysis of leading semiconductor companies’ knowledge flow network
This study (1) constructs a knowledge flow network for leading semiconductor companies; (2) seeks out how leading semiconductor companies can attain knowledge competencies (through patent activities or network position) via social network analysis; and (3) proposes critical strategic suggestions regarding knowledge flow networks in the industry. The results show (1) that a knowledge flow network with no isolators and Asian semiconductor firms are closely connected with other firms all over the world; (2) that patent activities are positively associated with central network positions and firm performance; (3) that closeness centrality is helpful for patent citation activities and also helps to achieve better performance; and (4) that semiconductor companies in Asia are also closely connected with others in the world.

The interaction between inter-firm and interlocking directorate networks on firm's new product development outcomes
This paper explores the interaction between a prominent board of directors and the network of inter-firm relationships on new product development. Specifically, we posit a positive interaction effect between a prominent board and the inter-firm network and structural holes positions on the number of new products developed by the firm. We test the theoretical framework on a sample of 1758 agreements among 1890 biopharmaceutical firms over the period 2006–2010. We find that by filtering, complementing and legitimizing information coming from the inter-firm network, a prominent interlocking directorate network can improve the inter-firm network's effects on new product development. We discuss important implications for how inter-personal networks (such as the board interlock directorate network) help to develop the effectiveness of inter-firm relationship networks in achieving new product development outcomes.

The Search-Transfer Problem: The Role of Weak Ties in Sharing Knowledge across Organization Subunits
This paper combines the concept of weak ties from social network research and the notion of complex knowledge to explain the role of weak ties in sharing knowledge across organization subunits in a multiunit organization. I use a network study of 120 new-product development projects undertaken by 41 divisions in a large electronics company to examine the task of developing new products in the least amount of time. Findings show that weak interunit ties help a project team search for useful knowledge in other subunits but impede the transfer of complex knowledge, which tends to require a strong tie between the two parties to a transfer. Having weak interunit ties speeds up projects when knowledge is not complex but slows them down when the knowledge to be transferred is highly complex. I discuss the implications of these findings for research on social networks and product innovation.

The Reification of Absorptive Capacity: A Critical Review and Rejuvenation of the Construct
We conduct a detailed analysis of 289 absorptive capacity papers from 14 journals to assess how the construct has been utilized, examine the key papers in the field, and identify the substantive contributions to the broader literature using a thematic analysis. We argue that research in this area is fundamentally driven by five critical assumptions that we conclude have led to its reification and that this reification has led to stifling of research in this area. To address this, we propose a model of absorptive capacity processes, antecedents, and outcomes.

The micro-determinants of meso-level learning and innovation: evidence from a Chilean wine cluster
Most analyses of the relationship between spatial clustering and the technological learning of firms have emphasised the influence of the former on the latter, and have focused on intra-cluster learning as the driver of innovative performance. This paper reverses those perspectives. It examines the influence of individual firms’ absorptive capacities on both the functioning of the intra-cluster knowledge system and its interconnection with extra-cluster knowledge. It applies social network analysis to identify different cognitive roles played by cluster firms and the overall structure of the knowledge system of a wine cluster in Chile. The results show that knowledge is not diffused evenly ‘in the air’, but flows within a core group of firms characterised by advanced absorptive capacities. Firms’ different cognitive roles include some—as in the case of technological gatekeepers—that contribute actively to the acquisition, creation and diffusion of knowledge. Others remain cognitively isolated from the cluster, though in some cases strongly linked to extra-cluster knowledge. Possible implications for policy are noted.

Measuring Firm-Level Innovation Using Short Questionnaires: Evidence from an Experiment
Little is known about innovation in developing countries, partly because of the lack of comparable and reliable data. Collecting data on firm-level innovation is challenging because of the subjective definition of what determines an innovation, a problem that is exacerbated in developing countries where innovation is likely to be more incremental and less radical. This paper contributes to the literature by presenting the results of an experiment aiming to identify the survey instrument that better captures firm-level innovation in developing countries. The paper shows that a small set of questions included in a multi-topic, firm-level survey does not provide an accurate picture of firm-level innovation and tends to overestimate innovation rates. Issues related to framing explain some of the unreliability of innovation responses, while cognitive problems do not appear to play a significant role.

Informational networks and innovation in mature industrial clusters
Abstract The position of a firm in inter-organizational networks that occur in geographic clusters can affect innovation. This study analyzes a wide range of ties and how they impact on the transmission of tacit and explicit knowledge. Thus, a firm's position influences its innovative performance in different ways, according to the type of network—tacit or explicit—and the type of innovation—process or product—under analysis. Few empirical studies have analyzed the relation between social networks and innovation in mature geographic clusters; an appropriate context bearing in mind the contingent nature of the relations under study. The results support the idea that a central position in both tacit and explicit knowledge networks is especially significant in the case of product innovation, but that the influence of structural holes is weaker. These findings contribute to the literature on clusters and social networks by explaining how strategic management of positions in knowledge networks can improve the innovative performance of a firm.

Power and Centrality: A Family of Measures
Although network centrality is generally assumed to produce power, recent research shows that this is not the case in exchange networks. This paper proposes a generalization of the concept of centrality that accounts for both the usual positive relationship between power and centrality and Cook et al.'s recent exceptional results.

Formation and dissolution of inter-firm linkages in lengthy and stable networks in clusters
Firms aspire to take advantage of technical and business networks through inter-organizational interactions to improve performance. Consequently, researchers are increasingly focusing on the dynamics and implications of network formation at both local and global levels. The recent research trend does not consider a monotonic effect and simplistic approach to proximity because proximity is a complex multidimensional concept. Using data from a foodstuffs cluster in the Valencian region (Spain) and advanced econometric methods such as Exponential Random Graph Models, this study aims to clarify the detrimental effects and complementarities that may arise among proximity dimensions. After controlling for network endogenous forces and firm characteristics, findings reveal the negative effect of cognitive and institutional proximity dimensions on the creation of linkages in advanced stages of the cluster life cycle. Furthermore, social proximity and geographical proximity favor the formation of inter-firm relationships and reinforce the organizational dimension.

Network dynamics in regional clusters: Evidence from Chile
Abstract A wealth of empirical literature shows that one of elements of success for regional clusters is that they facilitate the formation of local inter-organizational networks, which act as conduits of knowledge and innovation. While several studies analyse the benefits and characteristics of regional cluster networks, very little is known about how such networks evolve over time and the extent to which their dynamics can affect development processes. Using longitudinal data on a wine cluster in Chile and Stochastic Actor-Oriented Models (SAOM) to measure network dynamics, this paper examines the microdynamics underpinning the formation of new knowledge ties among wineries. It finds that the coexistence of cohesion effects (reciprocity and transitivity) with the weak knowledge bases of some firms in the cluster contribute to a stable informal hierarchical network structure over time. The empirical results have implications for theories on network dynamics in regional clusters and cluster policies.

SPSS and SAS procedures for estimating indirect effects in simple mediation models
Researchers often conduct mediation analysis in order to indirectly assess the effect of a proposed cause on some outcome through a proposed mediator. The utility of mediation analysis stems from its ability to go beyond the merely descriptive to a more functional understanding of the relationships among variables. A necessary component of mediation is a statistically and practically significant indirect effect. Although mediation hypotheses are frequently explored in psychological research, formal significance tests of indirect effects are rarely conducted. After a brief overview of mediation, we argue the importance of directly testing the significance of indirect effects and provide SPSS and SAS macros that facilitate estimation of the indirect effect with a normal theory approach and a bootstrap approach to obtaining confidence intervals, as well as the traditional approach advocated by Baron and Kenny (1986). We hope that this discussion and the macros will enhance the frequency of formal mediation tests in the psychology literature.
