Behavioral Decision-Making of Key Stakeholders in Public-Private Partnerships:A Hybrid Method and Benefit Distribution Study

Public-private partnerships(PPPs)have been used by governments around the world to procure and construct infrastructural amenities.It relies on private sector expertise and funding to achieve this lofty objective.However,given the uncertainties of project management,transparency,accountability,and expropriation,this phenomenon has gained tremendous attention in recent years due to the important role it plays in curbing infrastructural deficits globally.Interestingly,the reasonable benefit distribution scheme in a PPP project is related to the behavior decisionmaking of the government and social capital,aswell as the performance of the project.In this paper,the government and social capital which are the key stakeholders of PPP projects were selected as the research objects.Based on the fuzzy expected value model and game theory,a hybrid method was adopted in this research taking into account the different risk preferences of both public entities and private parties under the fuzzy demand environment.To alleviate the problem of insufficient utilization of social capital in a PPP project,this paper seeks to grasp the relationship that exists between the benefit distribution of stakeholders,their behavioral decision-making,and project performance,given that they impact the performance of both public entities and private parties,as well as assist in maximizing the overall utility of the project.Furthermore,four game models were constructed in this study,while the expected value and opportunity-constrained programming model for optimal decision-making were derived using alternate perspectives of both centralized decision-making and decentralized decision-making.Afterward,the optimal behavioral decision-making of public entities and private parties in four scenarios was discussed and thereafter compared,which led to an ensuing discussion on the benefit distribution system under centralized decision-making.Lastly,based on an example case,the influence of different confidence levels,price,and fuzzy uncertainties of PPP projects on the equilibrium strategy results of both parties were discussed,giving credence to the effectiveness of the hybrid method.The results indicate that adjusting different confidence levels yields different equilibriumpoints,and therefore signposts that social capital has a fair perception of opportunities,as well as identifies reciprocal preferences.Nevertheless,we find that an increase in the cost coefficient of the government and social capital does not inhibit the effort of both parties.Our results also indicate that a reasonable benefit distribution of PPP projects can assist them in realizing optimum Pareto improvements over time.The results provide us with very useful strategies and recommendations to improve the overall performance of PPP projects in China.

Study On Benefit Distribution of Improved Shapley Value in Fresh Agricultural Cold Chain

This article studies the problem of fresh agricultural cold chain and constructs a comprehensive benefit distribution model with improved Shapley value.First of all,this article considers the influence of input factors,risk factors,effort level on benefit distribution,and uses the entropy method,the order relationship analysis method to determine the benefit distribution coefficient under each influence factor.Then,this article establishes a comprehensive benefit distribution model,and uses the Topsis method to calculate the weight of each participating enterprise.Finally,the simulation result shows the feasibility and effectiveness of the proposed methods.The profit distribution model in this article takes into account the degree of contribution to participating enterprises to the cooperation and their satisfaction with the benefits distribution,solves the problem of unfair benefits distribution of the fresh agricultural cold chain,and thus promotes the stability of the cooperation among participating enterprises.

Competitive Equilibria and Benefit Distributions of Population Production Economies with External Increasing Returns

Inspired by the work of population games,we establish the model of population production economies with external increasing returns and introduce the notion of competitive equilibria.We first prove the existence of competitive equilibria under some regular assumptions.Furthermore,we assume that there exists the cooperative behavior of different populations.By proving the existence of transferable utility(TU)core,we analyze the benefit distributions of population production economies with external increasing returns.

Benefit allocation model of distributed photovoltaic power generation vehicle shed and energy storage charging pile based on integrated weighting-Shapley method

In this study,to develop a benefit-allocation model,in-depth analysis of a distributed photovoltaic-powergeneration carport and energy-storage charging-pile project was performed;the model was developed using Shapley integrated-empowerment benefit-distribution method.First,through literature survey and expert interview to identify the risk factors at various stages of the project,a dynamic risk-factor indicator system is developed.Second,to obtain a more meaningful risk-calculation result,the subjective and objective weights are combined,the weights of the risk factors at each stage are determined by the expert scoring method and entropy weight method,and the interest distribution model based on multi-dimensional risk factors is established.Finally,an example is used to verify the rationality of the method for the benefit distribution of the charging-pile project.The results of the example indicate that the limitations of the Shapley method can be reasonably avoided,and the applicability of the model for the benefit distribution of the charging-pile project is verified.

Countermeasures to Achieve High-quality Development of Dairy Industry in Xinjiang:A Case Study of Tianrun Dairy Industry

As a high-quality milk source base in China,Xinjiang has an innate foundation for the development of modern high-quality milk industry.In this paper,it was pointed out that the uneven distribution of interests between the upstream and downstream of the industry was the influencing factor restricting the development of modern dairy industry in Xinjiang.At the same time,the related information of Tianrun Group,which was the leading enterprise in Xinjiang,was analyzed.According to analysis,it was found that through the construction and development of large-scale,standardized and modern milk source base,balance of the upstream and downstream interests,improvement of the combination system of planting and breeding,the added value of products was enhanced and the anti risk ability of enterprises was increased.In addition,it was also pointed out that under the leadership of leading enterprises,Xinjiang would embark on the development road of modern high-quality milk industry with circular economy,resource-saving,environment-friendly,quality and efficiency,operation-saving,independent innovation and industrial integration in the future.

A Study on the Mutual Rental Model of Container Shipping Alliance Cabins based on Blockchain

As one of the main modes of capacity sharing in the shipping alliance,the essence of which is the space mutual rent transaction among members.However,under the current trading system,the sharing of capacity between shipping enterprises requires a lot of transaction costs and communication costs,cooperation efficiency is not high,and there is a certain competitive relationship between enterprises,they work for their own interests,resulting in more difficult cooperation,and blockchain consensus mechanism,intelligent contracts,distributed bookkeeping and other characteristics can solve these problems of alliance cooperation.Therefore,based on the idea of blockchain,this paper designs a model of mutual lease cooperation in shipping union cabins,gives the model and process of mutual lease transactions based on blockchain,realizes mutual trust and win-win situation among members,simulates through the combination of Hyperledger Fabric and Matlab,and verifies the applicability of blockchain to shipping alliance capacity sharing cooperation.
