In the new era of socialist construction with Chinese characteristics,the CPC Central Committee proposes to adapt,grasp and lead the new normal of economic development.Especially in the face of unprecedented challenges to economic development,the state especially proposes to ensure the stability of the industrial chain and supply chain.As a pillar industry in China,the construction industry has the problems of low profit,low output value and difficult development of enterprises.At the same time,the situation of large but not strong construction industry has not changed fundamentally,which restricts the growth of construction profit.In recent years,with the advantages of construction supply chain continue to highlight,more widely used in the construction industry,construction supply chain can effectively promote the stable operation of construction projects,improve the profit of construction enterprises.However,the distribution of interests among construction enterprises is an influencing factor that restricts the development of construction supply chain,and it is necessary to reasonably allocate the profits among construction enterprises.Therefore,this paper uses the benefit distribution model of construction supply chain based on multi-factor improved Shapley value to solve the problem of unreasonable benefit distribution between enterprises in construction supply chain,and improve the cooperative relationship between construction enterprises and optimize the operation of construction supply chain.This paper first discusses the research background of benefit distribution in construction supply chain,and puts forward the research significance of this paper.In view of the unreasonable benefit distribution in construction supply chain,this paper puts forward the research problem,and discusses the research framework,technical route and innovation of this paper.Secondly,the research status of multi-factor construction supply chain and Shapley value based profit allocation of construction supply chain are summarized and reviewed.Then,the construction principles and ideas of the index system of the influencing factors of the benefit distribution of the construction supply chain are expounded.On this basis,the index system of the influencing factors of the benefit distribution of the construction supply chain is established by using the literature analysis method and the questionnaire survey method,and the indexes of each influencing factor are analyzed.The weight of the influencing factors is determined by combining the analytic hierarchy process(AHP)and the fuzzy comprehensive evaluation method.Aiming at the established index system of benefit distribution influencing factors,a benefit distribution model of construction supply chain based on multi-factor improved Shapley value is constructed.Finally,a construction project adopting the operation mode of construction supply chain is selected,and the benefit distribution model of construction supply chain based on multi-factor improved Shapley value is applied to practical construction projects.At the same time,the results of benefit distribution are compared with the benefit value of independent operation of construction enterprises,and the reliability and applicability of the model are tested.According to the actual case verification model,the results show that:(1)By improving the original Shapley value method,considering the impact of resource investment,risk factors and contribution on the distribution of benefits,the income after distribution is higher than that of independent operation of construction enterprises.(2)Through the profit distribution model of the construction supply chain based on the improved Shapley value of multiple factors,it can be seen that in the construction supply chain,when the investment of the construction enterprise is larger,the risk it faces is more,and the contribution degree is higher,the income that the construction enterprise can obtain is higher.(3)The benefit distribution model of construction supply chain based on multi-factor improved Shapley value can provide a reasonable benefit distribution scheme for node construction enterprises,so as to improve the overall interests of the construction supply chain. |
