China’s Policy Environment’s Development and Path from the Perspective of Policy Sustainability: A Visual Analysis Based on CNKI and WOS

In this paper, we examine China’s policy environment from the perspective of policy sustainability. Through our use of the CiteSpace and NVivo software, the literature on the policy environment is visualized using a knowledge graph analysis and a content analysis of highly cited papers. The analysis shows that: the number of published papers on “policy environment” is on the rise, and the research prospect is broad. There is a lack of communication and cooperation between domestic authors and a close relationship between international authors. The main research countries included the USA, Switzerland, Finland, Ireland, and Austria, etc. Domestic research focuses on vehicles for high-quality economic and social development, while international research focuses on theoretical model discussion. The domestic optimization path focuses on the transformation from “Sending blood” (“ShuXieShi”) to “Making blood” (“ZaoXieShi”), while the international research focuses on the main line of “public health and environmental protection”. Domestic research focuses on fostering a sound business environment, while international research focuses on the public, political and professional aspects of health and medical policy environment. On the whole, in the future, we should improve the adaptability of the policy environment, optimize the policy implementation environment, and establish the interaction mechanism of policy environment optimization to achieve policy optimization.
