摘　　要：在城市层面,影响基础设施PPP(公私合营模式)项目融资额的因素具有多样性。本文基于2015—2017年我国地级市面板数据,采用空间回归模型对地级市基础设施PPP项目融资额的影响因素进行实证分析,并验证了PPP项目融资额在空间层面具有溢出效应。研究结果表明:空间误差模型相比混合OLS回归模型,对于分析PPP项目融资额影响因素的拟合效果更好;PPP项目融资额在城市层面上具有显著的正向空间溢出效应,即一个城市PPP项目融资额更容易受到相邻城市PPP项目融资额的影响。地方政府财政缺口、地区生产总值、固定资产投资额、人口密度对PPP项目融资额虽然都具有显著相关关系,但在不同地区间影响的差异性较大。地方政府财政缺口在中东部城市与PPP项目融资额呈现显著正相关,即地方政府财政缺口越大,城市越倾向于采用PPP模式进行基础设施投融资;而在西部城市,两者间这种相关关系则不显著。At the city level,factors that affect the financing amount of infrastructure PPP projects are diverse.Based on the panel data of prefecture level cities from 2015 to 2017,this paper makes an empirical analysis on the influencing factors of Infrastructure PPP financing in China by using the spatial regression model and verifies the spatial spillover effect of the financing amount of PPP projects.The results show that the Spatial Error Model has a better fitting effect on analyzing the influencing factors of the financing amount of PPP projects compared with the mixed OLS regression model.The financing amount of PPP project in China has a significant positive spatial spillover effect at the city level.The amount of PPP project investment in a city will be affected by the amount of PPP project investment in neighboring cities.Factors including local government financial situation,GDP,fixed asset investment and population density have significant correlation with the financing amount of PPP project,and the impact varies in different regions.In terms of local government’s financial situation,there is a significant positive correlation between the financing amount of PPP project in the Middle East of China.The larger the fiscal gap of local governments,the more inclined they are to use PPP mode for infrastructure financing.While,there is no significant correlation between these factors and the financing amount of PPP project in the West.
