摘要: 城市生态文明建设依托于生态效率的改善,基于2005—2016年长江经济带107座城市面板数据,采用超效率SBM(slacks-based measure)模型测算生态效率,并结合探索性空间分析与空间马尔科夫链等探讨生态效率时空演化格局的内在规律, 实证分析生态效率驱动因素的影响效果。研究表明:2005—2016年经济带生态效率总体呈平稳态势,上、中、下游呈现“阶梯型”分布,下游依次优于中游和上游地区,部分地区生态效率呈“两级型”分化趋势;城市间生态效率发展存在空间联动效应,与生态效率高的城市为邻,其正向溢出作用促进城市状态向高水平跃迁,而与生态效率低的城市为邻,其负向作用拉动城市状态向低水平发展;人口规模与产业升级对经济带不同流域具有异质性作用,其提升下游生态效率而抑制中游和上游生态效率,产业升级与生态效率存在“U”型关联,意味着产业升级在短期内并不能使生态效率状态改善,而经济发展有利于促进生态效率向高水平状态演变。

Abstract: Urban ecological civilization depends upon ecological efficiency. This paper, based on the panel data from 2005 to 2016 of 107 cities in Yangtze River economic zone, uses SBM to measure their ecological efficiencies and to discuss their temporal-spatial evolution rules of ecological efficiency by means of exploring spatial analysis and spatial Markov Chain, and studies the impacts of their driving forces. The study shows a general stable ecological efficiency as an upward staged distribution among up-, middle- and down-stream with partial areas showing polarization. There is a spatially connected effect in ecological efficiency development among cities. Cities of high ecological efficiencies promote their neighboring cities by positively overflowing, and cities of low ecological efficiencies pull down their neighboring cities. Population scale and industrial upgrade play a different role in different streams, promoting ecological efficiency of the down-stream but suppressing that of the middle- and up-stream. U-shaped connection between industrial upgrade and ecological efficiency implies that ecological efficiency may not be improved during industrial upgrade in a short term. Economic growth boosts a higher ecological efficiency.

Key words: Yangtze River economic zone, urban ecological efficiency, temporal-spatial evolution, driving forces
