生态效率是循环经济的合适测度

Eco-efficiency as the Appropriate Measurement of Circular Economy

发展循环经济已经成为我国未来国民经济和社会发展的重要战略之一,但是循环经济发展的度量问题还有待进一步研究。本文首先论述循环率并非循环经济的科学测度,然后在阐明循环经济的本质是提高稀缺性自然资本的生产率的基础上,指出循环经济的发展可以用生态效率指标来度量。最后评述了Seiji Hashimoto和Yuichi Moriguchi建议的描述社会物质代谢的六个指标,并根据这些指标在确定政策目标时应该具备的标准和计算这些指标存在的问题,提出基于DMI、DPO和GDP的生态效率指标可以作为循环经济发展的科学度量指标。

Although developing Circular Economy has been one of the most important strategies for China to boost its economic and social progress in the coming five years so far, further studies are needed to take up on measurement on Circular Economy development. Therefore, this paper attempts to solve the problem of the measurement of Circular Economy by introducing Eco-efficiency. First of all, it demonstrates that recycling rates are not the very measurement of Circular Economy. Next, it argues that developing Circular Economy is in essence to improve eco-efficiency . Finally, according the six indicators of material cycles for describing society＇ s metabolism proposed by Seiji Hashimoto and Yuichi Moriguchi, it puts forward that the appropriate indicators for measuring Circular Economy are the eco-efficiency indicators combining DMI and DPO with GDP, as DMI and DPO is the two indicators of material flow and GDP is an economic indicator used widely.
