Abstract: Aiming at the reality that informal channels in closed-loop supply chains promote resource recycling and reuse while causing secondary pollution to the environment, this paper defines the resource-environment equivalent to represent the performance of both resource recycling and pollution effects of the channels, compares and analyzes the economic effects and resource recycling effects of informal channels with government reward and punishment mechanism by using mathematical optimization and numerical simulation experiments, induces two general theorems for informal channel to achieve positive social effects, and explores the characteristics of the social effects of informal channels under different recycling rates and reward-punishment intensity, and provides reference suggestions and analysis methods for the government to govern informal channels.

Key words: closed-loop supply chain, reward-punishment mechanism, informal channel, resource-environment equivalent

摘要： 针对闭环供应链非正规渠道在促进资源回收再利用的同时又对环境造成二次污染的情况,给出资源回收当量指标以综合考量渠道资源回收和再造污染效应,利用数学优化和数值仿真方法对比分析存在政府奖惩机制下非正规渠道的经济效应和资源回收效应,获得了非正规渠道积极社会效应的通用定理以及不同再造回收率和奖惩强度下非正规渠道社会效应的特点,给出了政府治理非正规渠道的参考建议和分析方法。
