基于绿色闭环供应链的低值可回收物政府补贴研究

Low Value Recyclables Based on a Green Closed-Loop Supply Chain Research on Government Subsidies

摘要: 针对各类低值可回收物进行一刀切补贴的现状，本文以制造商、第三方回收商和消费者组成的绿色闭环供应链为研究对象，在政府补贴第三方回收商的情况下，构建了同时考虑到经济因素和环境影响的低值可回收物社会效益模型。本文以废玻璃与废纸类为例，通过理论证明和数值仿真验证模型的有效性，结果表明：政府补贴对不同种类的低值可回收物的影响程度不同，应切合各类低值可回收物实际情况对其进行分类补贴。

Abstract: In response to the current situation of providing comprehensive subsidies for various types of low value recyclables in Shanghai, this article takes a green closed-loop supply chain composed of manufacturers, third-party recyclers, and consumers as the research object. In the case of government subsidies for third-party recyclers, a social benefit model for low value recyclables is constructed that considers both economic and environmental factors. This article takes waste glass and paper as examples and verifies the effectiveness of the model through theoretical proof and numerical simulation. The results show that government subsidies have varying degrees of impact on different types of low value recyclable materials and should be classified and subsidized according to the actual situation of each type of low value recyclable material.
