Based on the impact of undesired output and the recycling characteristics of circular economy, this paper reconstructed the evaluation index of circular economy efficiency of Chinese provinces and cities, took the data of 10 provinces and cities in eastern China from 2011 to 2017 as the research object, and analyzed the efficiency of circular economy in eastern China by using the data envelopment analysis model. Research results show that: (1) From 2011 to 2017, the average efficiency of circular economy in 10 provinces and cities in eastern China was low, with serious two-level differentiation. From 2011 to 2015, the average efficiency of circular economy in all provinces and cities showed a slow downward trend, slightly recovered in 2016, and slightly declined in 2017.(2)In 2017, the pure technical efficiency of eastern China is high, but the scale efficiency is low. Therefore, Eastern China should first improve the scale efficiency, and then improve the pure technical efficiency. (3) In 2017, Tianjin, Jiangsu, Guangdong and Hainan focused on improving their scale efficiency, while Hebei, Zhejiang, Fujian and Shandong need to improve their pure technical efficiency and scale efficiency at the same time. |
