On the Second-best Policy of Household's Waste Recycling

This study analyzes the second-best household's waste recycling policy. If we assume the first-best economy with no illegal disposal or transaction costs, then unit pricing, an advance disposal fee and a recycling subsidy are required in order to achieve the social optimum such that both the sum of unit pricing and an advance disposal fee and the sum of unit pricing and a recycling subsidy are equal to the marginal disposal cost. Furthermore, the first-best outcome can also be obtained by a producer take-back requirement system.In the real economy, however, various factors prevent the first-best optimal outcome. In this study we consider two factors, one being the transaction cost associated with a recycling subsidy (or refund) and the other being illegal disposal by the consumer. If a recycling subsidy (or a deposit-refund system) is adopted, a transaction cost associated with it will be generated. Alternatively, if unit pricing is adopted, some of the consumed goods may be disposed of illegally. We show the complete trade-off between unit pricing and a recycling subsidy. In other words, we can not adopt unit pricing and a recycling subsidy simultaneously. As a result, there are three candidates for the second-best policy: unit pricing with an advance disposal fee, a deposit-refund system, and a producer take-back requirement system.Which of these three policies is the second-best policy will depend on the relative magnitude of the price of a recycled good and the marginal transaction cost associated with a recycling subsidy (or the refund in a deposit-refund system). Generally, if the price of a recycled good is positive and the marginal transaction cost is relatively high, unit pricing with an advance disposal fee is the second-best policy. However, where the price of a recycled good is negative and the marginal transaction cost is relatively high, a producer take-back requirement system is the second-best policy. Further, where the marginal transaction cost is relatively low, a deposit-refund system is the second-best policy, regardless of whether the price of a recycled good is positive or negative.

资源再生产业特征解析:基于“结构-行为-绩效”范式的研究

借鉴经典"结构—行为—绩效"范式,以资源型产业为参照对象,从资源再生产业的市场结构、市场行为和市场绩效三个角度,对资源再生产业特征进行深入解析,研究认为:资源再生产业是一个"落脚自由"的产业,技术弹性大,产业链较长,产业关联度大,具有规模经济性,兼具劳动密集型和技术密集型双重特征。这样的市场结构,决定了其市场波动性大,生产规模较小,经营灵活;反映到市场绩效上,其环境外部性表现出双面性,既具有明显的环境正外部性,又表现了很强的负外部效应。     

小件电子产品回收物流网络模型与实证研究——以废弃手机为例

每年我国都产生大量的小件电子废弃物,小件电子废弃物的资源化回收利用成为一个新的环境问题.本文以废弃手机为例,首先做了一个废弃手机回收的物流网络设计,然后建立了废弃手机回收的物流模型,最后通过利用VC++6.0软件编程求解对广西地区的废弃手机回收问题进行了实证分析,根据软件的求解结果,提出了一个以废弃手机为例的电子废弃物回收物流设计的战略网络模型.     

城市典型废弃物循环利用体系建设——日本的实践与启示

日本是循环经济管理理念和发展水平较为领先的国家之一,也是我国发展循环经济的一个重要借鉴和国际合作对象.文章从立法、全流程管理、分类管理和市场机制四个方面,系统而扼要地介绍了日本建设城市典型废弃物循环利用体系的主要做法和成效,包括:逐步推进建立和完善废弃物循环利用法律体系;结合责任分担制和延伸生产者责任制,实施全流程链条式管理;针对性地建立废弃物循环利用体系和处理方法,实现资源效用最大化;政府立法和规划引导,逐步形成以市场机制为主的废弃物循环利用体系.在此基础上,文章有针对性地提出了建立和完善我国城市典型废弃物循环利用体系的若干启示和建议,主要包括:理顺管理体制、完善现有体系、加大薄弱环节工作力度和调动利益相关者积极性四方面.     

Future perspectives on the role of extended producer responsibility within a circular economy: A Delphi study using the case of the Netherlands

Extended producer responsibility (EPR) is a proposed policy approach to promoting the circular economy (CE) within the European Union. This research used a policy Delphi to explore perspectives on improving EPR policies to further contribute to the CE goals of the Netherlands. Both the potential improvement and critical reflections discussed by CE and EPR experts and practitioners from this study contribute to a more detailed understanding of the future governance of CE practices. We present various activities to improve EPR and insights from Delphi participants that emerged from the study. This paper shows that whilst actors agree, in essence, that there is a need for modifying EPR, what the specific changes to the form are and to whom the new responsibilities apply is contested.
