The Analyse Of Public Service PPP Mode Supply Efficiency In China And The Influencing Factors

As social public interest's carrier,public service facilities construction is an important breakthrough for our country's administrative system reform,and its effective supply is the key to solve livelihood issues.Now,in the new normal Chinese economy steps in the high-middle speed growth stage under downward pressure and public finance is ovweloaded.Hence,improving public service supply efficiency and innovating public service input mechanism have become the urgent affairs.In recent years,as a great creation of public service supply mechanism,PPP mode receives extensive attention from all sectors of society.It replaces traditional mode of supplying publice product and service by public sectors alonely with the advanteges of risk sharing,benefit sharing,product lifecycle management and becomes new help of supply-side structural reform.Government gives much enthusiasm to PPP projects and support its development by establishing PPP investment fund and substituting subsidies with rewards,but low signing rate must bring a series of questions.How effective does PPP mode supply public service? Does efficiency esist regional difference? Which factors restrict improvement of PPP mode supply efficiency? These questiones' discussion are very important to development PPP mode and formulate relative policy.This paper takes 2009-2014 panel data of our country 30 provinces as sample and adopts DEA-Tobit model to analyze public service PPP mode supply efficiency and its influencing factors.Firstly,this study qualiatively elaborates development history and current situation of PPP mode supply and summarize success and dilemma.Then,based on three infrastructure field of erengy,transport and water,this study designs input-output system and uses DEA model to estimate comprehensive efficiency,technical efficiency,scale efficiency.Finally,on the base of empirical assumption,this research structures limited dependent variable Tobit model,takes comprehensive efficiency as the dependent variable,and empirically analyses the influencing characteristic and mechanism of urbanization level,government scale,residents' educational level,marketization degree,FDI dependence,fical decentralization,economic developmant level.Based on the full text,three basic conclusions are drawn.Firstly,promoting PPP mode in public services has been an irresistable trend and expectations of people.Secondly,DEA model estimation results show that public service PPP mode supplyefficiency is low at present in China and esists regional difference.Thirdly,urbanization level,government scale and marketization degree have a positive effect to PPP mode supply efficiency;fical decentralization,economic developmant level,and FDI dependence have a nagetive effect to PPP mode supply efficiency.In light of the above research conclusions,this paper gives six policy suggestions.Firstly,perfecting legal guarantee and inspiring confidence of social capital participating in PPP projects.Secondly,quickening new-type urbanization construction and generating the scale economic effect.Thirdly,strengthening talent cultivation and improving government management efficiency.Fourthly,promoting interest marketization reform further and optimizing financial environment.Fifthly,buliding perfect PPP investment finance and taxation policy support system.Sixthly,inclining PPP pilot projects to midwest area and enhancing accumulation investment effect.
