摘要
提升城市生态效率符合生态文明建设的内涵要求。以长江经济带107座城市为研究对象,在利用超效率SBM测度生态效率指数以及建立产业升级二维指标的基础上,构建广义动态空间模型,探讨产业高级化和产业合理化对生态效率的作用机理。结果显示:城市生态效率在长江经济带流域间存在梯级差异,下游城市生态效率普遍较高,中上游城市生态效率则进步明显。产业合理化在本地效应和溢出效应的双重作用下促进生态效率进步,产业高级化则更多体现在正向溢出效应,且在不同流域对城市生态效率产生异质性作用。伴随经济水平提升,产业升级对城市生态效率的促进效应愈发显著。
Industrial structure upgrading has double effect on urban ecological efficiency in space.Taking 107 cities in the Yangtze River Economic Zone as study subject,in this paper,super-SBMeco-efficiency index and industrial upgrading indexes are measured and then,generalized dynamic spatial panel econometric model is established to analyze driving mechanism of the industrial structure optimization and rationalization on urban eco-efficiency.The results show that urban eco-efficiency has positive spillover effect and negative hysteresis effect,and there exists a ladder difference among the river basins.The ecological efficiency of cities in the lower reaches is generally higher,while that in the middle and upper reaches is obviously improved.Industrial structure rationalization accelerates eco-efficiency improvement from aspects of positive spillover effect and negative hysteresis effect,however,industrial structure optimization reflects positive spillover effect,and exerts heterogeneity effect to eco-efficiency in different basins.Simultaneously,with the improvement of economic level,the acceleration of industrial structure upgrading to eco-efficiencies′increasingly significant.
