激励居民参与环保化回收废弃家电及电子产品的系统动力学模型

摘要/Abstract

废弃家电及电子产品处理不当会造成严重污染,鉴于青岛是国家发改委确定的废旧家电及电子产品回收处理体系建设试点城市,实地调研主要选择青岛市,调研了家电及电子产品保有状况、淘汰状况、回收体系状况、处理体系状况,提出了青岛市及我国废弃家电和电子产品回收处理体系存在的关键问题之一:居民交投正规回收经营者、有资质处理企业的比例极低,大部分出售给回收游击队.采用系统动力学研究激励居民参与环保化回收废弃家电及电子产品的策略.绘制了我国废弃家电及电子产品回收处理体系的因果回路图、存量流量图;并以青岛市为例给出存量流量图的方程式,进行了现实性检验、极端检验,围绕政府增加环保宣传费用、正规回收经营者提高服务或回收价格进行了策略分析.

Research on Environmental Feedback Mechanism Based on System Dynamics

摘要/Abstract

Cultural science and technology integration and innovation has become a new way to promote the coordinated development of culture and science and technology. Based on the theory of fusion innovation and collaborative innovation, this paper applies the basic principles of system dynamics to construct the causality model of the interaction between cultural system and technology system, and uses Vensim PLE software to simulate the system and analyze the path of cultural technology fusion innovation and its influencing factors. The research results show that: culture and technology integration innovation system is composed of complex feedback mechanisms that interact with each other. Each feedback loop represents the realization path of cultural science and technology fusion innovation. In the implementation path, cooperation between industry, universities and research institutes, market demand forecasting accuracy, innovation there is a significant positive impact between the perfection of incentive mechanism, the perfection of cultural intermediary service system and the integration of cultural science and technology innovation.
