Identifying factors affecting investment control in form of public-private partnerships for road traffic infrastructure

This study aims to determine the factors affecting investment control in the form of building-operate–transfer (BOT) contracts for road traffic infrastructure. It bases on investment practices in the form of PPP in general and BOT in particular in Vietnam as well as international experiences in implementing PPP projects (both successful and unsuccessful cases). Data is collected through in-depth interviews with 280 subjects with experiences in project management, PPP project management, and BOT project management and who are such service users, etc. After being collected, the data is analyzed qualitatively and quantitatively to remove duplicate factors and factors with insignificant impacts. The research results show that: The groups of factors such as the legal framework-policy, State management, investors, and risk management all affect the control of BOT project investment in road traffic infrastructure in Vietnam. From the above results, the authors propose a system of solutions to strengthen the control of investment in BOT road traffic infrastructure projects in Vietnam.
