【摘要】：我国正面临着非常严峻的资源短缺和环境污染问题。在废旧产品回收市场上,废旧家电的回收和处理方式很不正规,大部分报废的家电产品没有得到规范的处理,带来了严重的资源浪费和环境污染。回收市场上非正规回收市场份额较高,占据主导地位。我国已于2011年初在全国范围内正式施行废弃电器电子产品的回收处理条例,国家对电器电子生产商征收废弃产品处理费用、对正规废旧电器回收企业补贴基金的建立标志着我国生产者延伸责任制度的进一步完善。对废旧家电进行回收再利用可同时兼顾资源效益、环保效益与经济效益,是解决废旧家电引起的资源浪费与环境污染问题的有利武器。本文借助系统动力学原理,考虑回收处理过程中回收价格、回收速率、政府拆解补贴等变量的随机性与交互动态性,构建废旧家电回收的系统动力学模型。运用Vensim PLE软件进行模型的仿真、预测分析和关键参数的变动分析,对我国正规与非正规回收数量的发展规模及回收收益的变化趋势进行预测研究,并以政府拆解补贴、正规回收价格、政府投入的环保宣传费用和正规回收经营者投入的服务费用为例进行参数的变动分析,从而为政府和废旧电器回收商的决策提供更加全面动态的辅助决策信息支持。研究结果表明:政府拆解补贴和环保宣传费用的增加均能够促进废旧家电回收企业的回收与再利用活动。在短期,居民对提高回收价格更为敏感;但从长期来看,居民对提高政府投入的环保宣传费用和正规回收经营者投入的平均服务费用更为敏感。政府拆解补贴直接作用于回收再利用企业,在较长一段时期能有效刺激回收速率的增长,扶持正规回收经营企业的发展,但从长期来看,政府拆解补贴对回收速率的刺激作用将不断减弱。
[Abstract]:China is facing a very serious problem of resource shortage and environmental pollution. In the recycling market of waste products, the recycling and disposal of used household appliances is very irregular. Most of the discarded household appliances have not been standardized, which brings serious waste of resources and environmental pollution. The market share of informal recycling market is high. In early 2011, China formally implemented the regulations on recycling and disposal of waste electrical and electronic products, and the state imposed disposal fees on the waste products of electrical and electronic manufacturers. The establishment of the subsidy fund for the formal recycling enterprises of waste electrical appliances marks the further improvement of the extended producer responsibility system in China. The recycling and reuse of used electrical appliances can also take into account the resource efficiency. Environmental benefits and economic benefits are beneficial weapons to solve the waste of resources and environmental pollution caused by waste household appliances. Based on the principle of system dynamics, this paper considers the recovery price and recovery rate in the process of recovery and treatment. The randomness and interactive dynamics of government dismantling subsidy and other variables are analyzed, and the system dynamics model of recycling used household appliances is constructed. The simulation of the model is carried out by using Vensim PLE software. Forecast analysis and change analysis of key parameters, the development scale of formal and informal recovery quantity and the change trend of recovery income are forecasted and studied, and the government disintegrates the subsidy, the formal recovery price. The cost of environmental protection publicity invested by the government and the service cost invested by the regular recovery operator are analyzed for example. The research results show that: 1. The research results show that: 1. The research results show that the government and waste appliance recyclers can make more comprehensive and dynamic decision-making information support. The increase in government dismantling subsidies and environmental publicity costs can promote recycling and recycling activities of waste home appliances recycling enterprises in the short term. Residents are more sensitive to higher recovery prices; But in the long run, residents are more sensitive to increasing the government's environmental publicity costs and the average cost of services invested by the regular recycling operators. The government dismantling subsidies directly act on recycling enterprises. In a long period of time, it can effectively stimulate the growth of recovery rate and support the development of formal recycling enterprises, but in the long run, the incentive effect of government dismantling subsidies on recovery rate will be weakened.
