Viability Gap Funding PPP Project Private Enterprise Research On The Optimization Of Cooperative Behavior Incentive Mechanism

In view of the development characteristics of quasi-business infrastructure projects,the viability gap funding has been widely used as a reward mechanism.However,with the implementation of the viability gap funding PPP projects one after another,problems also emerged.Some projects could not guarantee the reasonable returns of private enterprise,resulting in the breakdown of the cooperation between government and enterprise,and the PPP projects have also failed.Through the analysis of some typical failure cases,it can be seen that these cases generally have the key problem of unreasonable incentive mechanism.Therefore,in order to improve the cooperation efficiency and sustainability of the viability gap funding PPP projects,the optimization of incentive mechanism has become a scientific problem to be solved urgently.In this paper,the viability gap funding PPP projects as the research object,explore how to optimize the incentive mechanism of such PPP projects,in order to maintain the stable cooperative relationship between government and enterprise.Through the analysis of the current situation of the incentive mechanism of the viability gap funding PPP projects,it is found that there are three main problems in the existing incentive mechanism,which are single incentive way,insufficient consideration of incentive preference and too rigid incentive intensity.On this basis,this study adopts the literature analysis method,through the analysis of the existing literature,summarizes the main factors that affect the incentive effect,and proposes the optimization path of the incentive mechanism.Secondly,according to the optimization path of the incentive mechanism,Stackelberg game method was used to clarify the optimization direction of the incentive mechanism to promote the cooperation of social capital,and the optimization of the incentive mechanism was preliminarily analyzed.Then,the calculation experiment simulation analysis method was used to enrich the incentive way,integrate the incentive preference and adjust the incentive intensity.More in-depth explanation of the incentive mechanism optimization principle.Finally,taking JQ urban cogeneration central heating project as an example,the practical successful management experience and simulation results are compared and analyzed,which further confirms the scientific and rational conclusion of this study,and verifies the practical guiding significance of this study.The results show that:(1)Due to the existence of diminishing marginal effect,a single incentive method is difficult to achieve good incentive effect.Therefore,in order to improve the incentive efficiency and stimulate the cooperation enthusiasm of Private enterprise,diversified incentive methods should be adopted to stimulate Private enterprise from multiple perspectives.(2)The setting of incentive intensity plays a decisive role in the incentive effect generated by the incentive mechanism.Too high or too low incentive intensity cannot achieve the best incentive effect.Therefore,the setting of incentive intensity should be integrated,coordinated and systematic,and take into account the change law of each subject’s income and cost.(3)In the implementation process of feasibility gap subsidy PPP projects,Private enterprise has a rational limitation.Based on this,in order to maintain the cooperation relationship of private enterprise,the incentive mechanism should focus on considering the incentive preference of private enterprise.
