铁路 EPC 项目总分包利润分配研究

为解决实施 EPC（设计—采购—施工）工程总承包模式的铁路项目中总承包方与分包方之间利润分配不均匀的问 题，选取总分包双方的利润为研究对象，在达到帕累托集体最优的基础上，运用 Shapley 值法对总分包方和分包方的利润进 行分配，建立了以设计单位牵头的铁路 EPC 项目总分包之间的利润分配模型，并针对项目特点，进行双方投入资源与铁路 项目风险分配的修正。模型确定了总分包集体最优效益下的各自利润和创新优化收益分配比例，为铁路 EPC 项目中分包合 同的制定提供依据。

Study on the Benefit Allocation Between the General Contractor and Subcontractor of Railway Projects in EPC Mode

To solve the problem of uneven allocation of benefit between the general contractor and the subcontractor in railway projects when using the EPC（Engineering—Procurement-Construction）mode，the benefits of both parties are selected as the research object. To achieve Pareto collective optimization, Shapley value method is used to distribute the profits of the total subcontractors and subcontractors. A profit distribution model between the total subcontractors of railway EPC projects led by design units is established. According to the characteristics of the projects, the allocation of resources invested by both parties and risks of railway projects are revised. The model determines the respective profit under the optimal benefit of the total sub-contracting group and the proportion of profit distribution under innovative optimization, which provides the solid foundation for the formulation of sub-contracts in railway EPC projects.
