废旧资源回收再利用是社会关注的热点问题，但闭环供应链成员间存在的信息壁垒导致回收再制造效率不高。基于云平台的思想解决闭环供应链回收再制造信息不对称的问题，构建了政府、回收商、再制造商之间的三方演化博弈模型，利用Lyapunov间接法和赫尔维兹稳定判据进行演化稳定分析，探究闭环供应链成员是否利用云平台进行信息共享的策略选择及其影响因素。采用Matlab进行仿真分析，为基于云平台进行回收再制造信息共享提供决策依据。研究表明：政府在演化博弈系统中起主导作用，采取适当的监管力度有利于回收再制造信息共享；回收商相较于再制造商的机会主义更显著，政府应关注对回收商的监管；形成行业联盟有利于回收再制造信息共享。“,”Recycling of waste resources is a hot issue of social concern, but the information barriers among members of the closed loop supply chain lead to the low efficiency of recycling and remanufacturing. Based on the idea of cloud platform, the problem of information asymmetry in recycling and remanufacturing in closed-loop supply chain was solved, and a tripartite evolutionary game model among government, recyclers and remanufacturers was built. The evolutionary stability analysis was carried out by Lyapunov and Herwitz stability criterion. The strategy choice and influencing factors of whether members of closed-loop supply chain use cloud platform for information sharing were explored. Finally, Matlab was used for simulation analysis to provide decision-making basis for recycling and remanufacturing information sharing based on cloud platform. The research shows that: The government plays a leading role in the evolutionary game system, and appropriate supervision is conducive to the sharing of recycling and remanufacturing information; The opportunism of recyclers is more obvious than that of remanufacturers, and the government should pay attention to the supervision of recyclers; (3) The formation of industry alliance is conducive to the sharing of recycling and remanufacturing information.
