Public-Private Partnership is a mechanism in which the public sector uses the capacity of the private sector to provide infrastructure services. Due to the economic and political conditions of governments, moving towards using the capacities of the private sector has become more necessary than ever. In this regard, examining the main obstacles to success in private and government partnership projects has been one of the main management issues in recent years. The purpose of this study is to investigate the main barriers to success in private and public sector participatory projects and a case study of Zanjan Provincial Deputy for Civil Engineering projects. In this research, which is an applied research, an attempt has been made to determine the main barriers to success in collaborative projects using quantitative methods and questionnaires. For this purpose, based on the four components of PEST analysis (political, economic, cultural and technical), the identified factors were classified and a questionnaire was formed. Demetel technique was used to analyze the collected questionnaires and the questionnaire was distributed using Cochran's formula among the statistical population. The results of the analysis of the questionnaires show the impact of all four main political, economic, cultural and technical components on the participation process. Among these, the criterion of political components with a normal weight of 0.180 is in the first priority. Economic criteria with normal weight of 0.162, technical criteria with normal weight of 0.087 and social criteria with normal weight of 0.066 have the following priorities, respectively.
