循环经济与低碳经济的关系分析——基于资源生产率

Analysis on Relationship between Circular Economy and Low-carbon Economy:Based on Resource Productivity

循环经济和低碳经济都是实现可持续发展的生产方式和生活模式,发展循环经济和低碳经济的根本共同点在于均需要提高广义资源生产率(生态效率),不同点在于实现可持续发展的途径和突破点等不同。本文基于资源产出率的理论分析、情景分析和实证研究,探讨了通过发展循环经济促进碳减排的途径。本文认为,通过提高资源生产率来提高碳生产率是可行的,其效果是资源效率效应和资源结构效应的叠加,可以此表征循环经济和低碳经济的相互关系。最后,我国1990—2005年的数据进行了实证分析。

Circular economy and low-carbon economy are two ways to achieve the goal of sustainable development.Based on the resource productivity,the basic common ground of developing circular economy and low-carbon economy is to raise the general resource productivity（eco-efficiency）,and the difference between them is the ways to reach sustainable development.This paper uses theoretical models,scenario analysis and empirical research on resource productivity to explore the ways to develop circular economy to promote carbon reduction.The theoretical models show that it is feasible to enhance resource productivity through increasing carbon productivity,and the synergy of resource efficiency effect and resource structure effect could characterize the relationship between circular economy and low-carbon economy.Finally,it uses China＇s economic data during 1990-2005 to verify this finding.
