摘　　要：实现最优工业生态效率对促进工业绿色发展有着重要的现实意义。本文通过非期望产出的SBM模型,测度长江经济带上中游代表性地区成渝经济圈和武汉都市圈26个城市2010—2021年工业生态效率,通过Arcgis可视化工具对比分析其时空演变规律,并运用Tobit模型和地理探测器模型分别识别工业生态效率的驱动因素。结果表明:1)两个城市群工业生态效率整体均呈现波动上升态势,且与最优效率还存在一定的差距;2)城市群内部的地级市之间效率值存在少部分两极分化的现象;3)工业生态效率受科技研发投入、经济发展水平、交通可达性、对外开放水平等多个因素的影响,其中经济发展水平和交通可达性对于工业生态效率的提升起到较强的促进作用,对外开放程度与科技研发投入对于工业生态效率的促进作用还不明显,还需要进一步提高外商投资水平和增强科技研发投入质量以实现其对工业生态效率的正向影响。为此,通过强化城市群内外部的融合发展、构建协同创新网络和提升对外开放水平,以提高长江经济带上中游地区工业生态效率水平,促进地区高质量发展。Realization of optimal industrial eco-efficiency is of significance to industrial green growth.This paper uses non-expected output SBM model to measure their 2010 to 2021 industrial eco-efficiency of 26 cities in Chengdu-Chongqing economic circle and Wuhan metropolitan circle as representative in the upper-to middle-stream of Yangtze River economic zone,and employs ArcGIS's visualization tools to compare their temporal-spatial evolution,and applies Tobit model and geographical detector model to identify their drives.It shows that their industrial eco-efficiency displays a fluctuating rising trend in two urban circles,with gap in the optimal efficiency.Polarizations partially exist inside prefectures in both circles.Industrial eco-efficiency is jointly constrained by R&D inputs,economy,transportation and openness,of which economy and transportation play a stronger promotion,others play a little in a need of raising foreign investment and intensifying research&development inputs to reach a positive promotion.This paper presents suggestions on strengthening an integrated development inside&outside of urban circle,establishing collective innovation network and increasing openness,aiming at promoting industrial eco-efficiency and local quality economic growth in the middle-and upper-stream of Yangtze River economic zone.
