Comprehensive Evaluation Of PPP Project Investment Environment Of Cities

With the acceleration of urbanization in our country and the increasing demand level of investment and construction of infrastructure in urban and rural areas,the scale of public infrastructure investment has increased sharply at all levels,and the local government debt risk is becoming more and more serious.Traditional government investment is difficult to meet the huge capital needs.In this case the application of PPP model born,and has become China's public infrastructure investment in the protagonist.However,due to the lack of mature experience in China and the characteristics of PPP mode,such as:PPP mode technology management is difficult,the operation process is complex,the professional ability is high,need a high level of government public governance and a sound sound market environment Factors,the PPP model can eventually be successful implementation,there is no uniform answer.In fact,the success of the PPP project is highly dependent on whether the internal and external conditions are met,especially if the investment environment provided by the city where the project is located is available.Therefore,the establishment of a scientific and reasonable evaluation index system,for the government to improve the city's PPP project investment environment,social capital optimization investment strategy is essential.This paper first summarizes the relevant literatures at home and abroad,analyzes the related concepts of PPP model and urban investment environment,and combines the concrete characteristics of external environment and the development of PPP model in China.Based on the existing research The paper analyzes the factors that influence the investment environment of the PPP model,and then starts from the urban level,and establishes a four-dimensional evaluation index system with the economic development status,the institutional environment factor,the government's management ability and the market development level as the core.Indicators were explained.Second,the use of analytic hierarchy process to determine the weight of each indicator.Then,the gray relational method is used to evaluate the PPP investment environment of sub-provincial cities,and the gray relational value is obtained and the evaluation results are analyzed.Finally,from the economic aspects,the government,innovation,talent to raise the sub-provincial city PPP project investment environment countermeasures and suggestions.The conclusion shows that the investment environment of PPP projects in sub-provincial cities is at a moderate level,but there are some differences between them.According to the evaluation results,these cities are divided into three categories.The first category contains Hangzhou,Qingdao.This type of city is characterized by the PPP project investment environment level is better,the indicators rank top,there is no short legs phenomenon.The second category includes Chengdu,Shenzhen,Ningbo,Shenyang,Jinan,Guangzhou,Nanjing,Xi'an,Dalian,Xiamen,Wuhan.This type of city is characterized by PPP project investment environment level in general,but some indicators ranked behind,there is a short leg phenomenon.The third category contains Harbin,Changchun.This type of city is characterized by PPP project investment environment is poor,although the indicators are more balanced ranking,but the indicators are poor level.
