中文摘要:
      以2012—2019年中国电器电子产品规范拆解处理数据为依据,分年度和区域分析了中国在电器电子产品领域推行生产者责任延伸制度所取得的成效,发现每千人收集台数、环境敏感性物质收集指数、可直接再生利用资源产出率等指标稳步增长。此外,通过求解Pearson相关系数并运用典型相关分析发现,在较高置信水平下,第一组指标(年度废弃电器电子产品处理基金核准补贴金额、从业企业数量、企业平均处理能力)和第二组指标(每千人废弃产品收集数量、环境敏感物质收集指数、可直接再生利用资源产出率),各指标两两之间显示出极强的相关度,且2个指标组的线性组合呈正相关。研究发现在一定前提条件下,通过增加从业企业数量,提高补贴金额或增大企业处理能力,能够促进每千人收集数量或环境敏感性物质收集指数2项指标的提升,但导致可直接再生利用资源产出率指标下降。
英文摘要:
      In this research,analysis of environmental and economic performance in different regions and years was carried out to assess the achievements of Extended Producer Responsibility system implementation for Electrical and Electronic Equipment,and found that the indicators,recycling number per 1000 people,collection index of environmentally sensitive substances,resource yield rate,were gradually improved after the impl ementation of Extended Producer Responsibility system.In addition,using the Pearson correlation coefficient and canonical correlation analysis methods,the correlation between indicators and indicator groups was discussed.It is found that at a high level of confidence,for the first group of indicators,amount of approved subsidy,number of enterprises engaged,average processing capacity,and the second group of indicators,recycling number per 1000 people,collection index of environmentally sensitive substances,resource yield rate show a strong correlation between each in dicator,and the linear combination of the two indicator groups is positive.The study found that under certain preconditions,by increasing the number of enterprises engaged,amount of approved subsidy or average processing capacity,it can promote performance indicators of recycling number per 1000 people and collection index of environmentally sensitive substances,and will reduce the indicator of resource yield rate.
