基于改进Shapley值的港口供应链融资联盟收益分配

Research on financing income distribution of port supply chain based on improved Shapley value

港口产业生态圈建设的大背景下,港口主导、多方参与的港口供应链融资联盟能够有效推动港口供应链金融创新,助力产业发展。为解决融资联盟的收益分配问题,对传统的Shapley值法进行改进,综合考虑资源投入、风险承担、信息共享水平及客户吸引力4个影响因素,并运用经TOPSIS法修正后的云重心法确定收益分配修正值,从而弥补Shapley值法的不足。算例结果表明,改进的Shapley值法在港口供应链融资联盟收益分配过程中更具公平性和合理性,有利于联盟的稳定发展。

Under the background of the construction of port industry ecosystem,the port leading and multi participation port supply chain financing alliance can effectively promote the financial innovation of port supply chain and help the industrial development.In order to solve the problem of income distribution of financing alliance,this paper improves the traditional Shapley value method,comprehensively considers the four influencing factors of resource investment,risk-taking,information sharing level and customer attraction,and uses the cloud barycenter method modified by TOPSIS to determine the revised value of income distribution,so as to realize the reasonable distribution of income.The result shows that the improved Shapley value method is more fair and reasonable in the process of income distribution of port supply chain financing alliance.
