基于修正夏普利(Shapley)值的装配式建筑产业链利益分配研究

自2015年以来，国家密集出台了一系列政策文件大力发展装配式建筑。装配式建筑的发展离不开其产业链的发展，而链接装配式建筑产业链的根本是利益。有效的产业链利益分配机制，能提高企业的积极性，使其成员企业形成一种良好的合作关系，而利益分配不均或不合理，企业就会退出产业链，对产业链造成破坏。故要保证装配式建筑的发展，产业链的稳定是前提，产业链上各相关企业的利益分配是关键。本文以装配式建筑产业链为研究对象，基于传统Shapley值模型，并根据装配式建筑的特点，将风险分担、信息共享、技术创新、企业投入作为修正因子对Shapley值进行修正计算，建立了修正Shapley值利益分配模型，以此模型为基础，研究装配式建筑产业链上下游各利益相关企业的利益分配问题，以求得科学、合理地利益分配方案，为解决此类产业链内各链节企业的利益分配问题提供参考。

Research on Profit Distribution of Prefabricated Building Industry ChainBased on the Modified Shapley Value

Since 2015, a series of policy documents were issued intensively to vigorously promote the development of prefabricated buildings. The development of prefabricated buildings is inseparable from the development of its industrial chain, and the fundamental link to the prefabricated building industry chain is interest. An effective industrial chain profit distribution mechanism can increase the enthusiasm of the enterprise and form a good cooperative relationship among its member companies. If the distribution of benefits is uneven or unreasonable, the enterprise will withdraw from the industrial chain and cause damage to the industrial chain. Therefore, to ensure the development of prefabricated buildings, the stability of the industrial chain is a prerequisite, and the distribution of the interests of related companies in the industrial chain is the key. This article takes the prefabricated construction industry chain as the research object. Based on the traditional Shapley value model, according to the characteristics of the prefabricated building, the risk sharing, information sharing, technology innovation, and enterprise input are used as the correction factors to modify the Shapley value, and the profit distribution model of the modified Shapley value is established. Based on this model, study the distribution of interests of various related enterprises in the upstream and downstream of the prefabricated construction industry chain, In order to obtain a scientific and reasonable profit distribution plan, it provides a reference for solving the problem of profit distribution of enterprises in each link of such an industrial chain.
