PPP模式下项目参与方信任对项目绩效影响研究

Study on the Impact of Project Participants'Trust on Project Performance under PPP Mode

基于交易成本理论,建立了多维度信任与PPP项目绩效之间的关系模型,考虑合作的中介效应和环境不确定性的调节效应。对121份有效问卷进行回归分析,结果表明能力、制度与诚信信任能够正向影响PPP项目绩效,合作在三个维度的信任与绩效关系中均起到了部分中介作用,环境不确定性能够增强能力信任与诚信信任对PPP绩效的影响,并从建立良好沟通平台、积极展现工作能力等方面提出改善PPP项目绩效的管理建议。明确了多维度信任对绩效的作用机理,所引入的中介变量与调节变量能够加强模型的解释性与适用性,有利于引导公私双方加强关系治理,促进PPP项目的绩效提升。

Based on the transaction cost theory,the relationship between trust between government and social capital and PPP project performance was modeled by considering the mediating effect of cooperation and the moderating effect of environmental uncertainty.Based on the regression analysis of 121valid questionnaires,the results show that competence,institutional and integrity trust can positively influence PPP project performance,cooperation plays a partial mediating role in the relationship between trust and performance in all three dimensions,and environmental uncertainty can enhance the influence of competence trust and integrity trust on PPP performance.Finally,management suggestions for improving PPP project performance are proposed in terms of establishing agood communication platform and actively demonstrating the ability to work.This paper clarifies the mechanism of multidimensional trust on performance,and the introduced mediating and moderating variables can enhance the explanatory and applicability of the model,which is conducive to guiding both public and private parties to strengthen relationship governance and promote the performance of PPP projects.
