广义物质循环模型及对循环经济的政策内涵

Models of Generalized Material Recycling and Its Policy Implication for Circular Economy in China

在传统经济增长模式下,我国资源开采、生产、消费及消费末端各个环节的环境问题都十分突出,然而传统的物质循环并不能从根本上解决我国经济增长与生态环境之间的矛盾。在总结传统物质循环的特点与局限性的基础之上,提出了旨在提高经济系统全过程资源效率与环境绩效的广义物质循环的概念及理论模型;剖析了广义物质循环的资源与环境政策内涵,并据此提出我国资源环境的生命周期政策途径;最后以广义物质循环的内涵及基本原则为指导,深入探讨了我国循环经济发展的资源政策与环境政策。本文认为,建立与发展以广义物质循环为核心的循环经济增长模式,是我国实现经济与环境持续协调发展的根本途径。

In the traditional mode of Chinese economy development, the environmental problems are so prominent in various economic processes, including resource extraction, production, consumption, and also post-consumption stage. However, the conventional material recycling is not an effective way to fundamentally solve the contradiction between economic development and ecological sustainability in China. Based on the analysis of the weaknesses and ineitqciencies of conventional material recycling, this paper proposes a theoretical model of generalized material recycling （GMR）, which is aimed at improving the resource efficiency and environmental performances in all the economic processes as a whole. Furthermore, policy implications of GMR from both resources and environmental level are analyzed and the life-cycle policy approaches are summarized accordingly. Finally, on the basis of the current situation in China, both resources and environmental policies of chinese Circular economy are discussed with the guide of the basic principles of GMR.
