Research On The Incentive Mechanism Of Public Participation Behavior In The Large-scale Public Projects Investment Decision

With the continuous advancement of the policy of"supplementing short-term investment and stabilizing investment"at the national level,all levels and local governments across the country,in light of local reality,have actively promulgated corresponding policies to promote the implementation of large-scale public investment projects.Investment decisions are particularly important in the construction of large public investment projects,and even determine the success or failure of the project.The realization of effective,reasonable and extensive public participation in the investment decision-making process is not only to ensure the scientificity and rationality of project decision-making,but also an important manifestation of paying attention to and realizing the democratic rights of the public.However,the current large-scale public investment projects in China mainly rely on government decision-making,and the existing decision-making mechanism often has the problems of insufficient participation of multiple subjects and lack of effective communication and collaboration among the subjects.In order to solve the above problems,this paper uses system dynamics and game theory research methods,combining theoretical analysis and empirical analysis,first constructing an overall system framework for public participation in large public project investment decision-making,depicting the interaction between factors that affect public participation behavior The relationship is established;secondly,the government encourages the public to participate in the decision-making micro-behavior evolution mechanism model,which simulates the game state of the three parties of government,the public,and the enterprise;finally,the network governance theory is introduced,and the public participation network is designed by summing up the system evolution rules and the factors affecting the public participation.To provide incentives for public participation and provide practical measures to encourage public participation.The research conclusion shows:?1?Use system theory to systematically define and analyze public participation in large public project investment decisions,and establish a public participation system framework;using game theory to explore the relationship between the government,the public,and enterprises from the perspective of government incentives,and build the relationship between the various subjects The dynamic evolutionary game model analyzes the macro and micro systems of public participation in decision-making.?2?During the investment decision-making process of large-scale public projects,the government,the public,enterprises,and third-party organizations have a synergistic effect on the effectiveness of public participation in decision-making through public participation breadth,public participation depth,and public participation validity.The decision-making behavior is related to multiple stakeholders and multiple influencing factors.?3?Explore the three-party evolutionary stability strategy of the government,the public,and enterprises,derive 9 effective local equilibrium points,and carry out strategic mutation simulation analysis to find that the evolutionary trajectory is finally in the state of D₄=?0,1,1?^-1,which confirms The interaction between the three parties,the three-party game group will eventually achieve a"non-incentive,participation,effort"stable state.?4?Simulation analysis of evolutionary systems found that the government can achieve good public participation effects by adopting incentive strategies in the early stages of decision-making.The hard work of enterprises also helps the public to enter a stable state of participation faster.The government's incentive costs and public participation The income of the company and the punishment of the company's lack of effort are the most important factors that affect the strategic choice of each subject.?5?Large-scale public project investment decision-making has the characteristics of a group and multi-participant main body network.Social networks can play an important role in information,resources and relationship carriers in public participation in decision-making.Network governance theory can be used to solve public participation problems and help build the public Participate in networked incentive mechanisms.This article enriches the relevant theories of investment decision-making and public participation in large-scale public projects,and has certain reference value to encourage public participation in public project activities.process.
