摘要： 绿色发展是长江经济带战略的首要要求，而创新是驱动区域绿色发展的核心要素。通过构建科技创新与绿色发展综合评价指标体系，以长江经济带108个地级及以上城市为研究对象，采用熵权Topsis法，耦合协调度模型和空间马尔科夫链方法，分析2006～2016年长江经济带科技创新与绿色发展的耦合协调水平、时空分布格局以及空间关联性演变。研究结果表明研究期内：（1）长江经济带科技创新和绿色发展指数总体上虽然均有一定的上升，但整体水平较低，2013年开始呈现同步增长的趋势；（2）科技创新与绿色发展的耦合度及协调度指数整体上呈上升趋势，但带内空间分异明显，长三角地区协调度明显高于其他地区；（3）科技创新与绿色发展的协调性呈现集群化现象，且具有“下游＞中游＞上游”的梯度化空间分异特征，低水平协调的城市单元可以划分为科技创新领先区、绿色发展领先区和平衡区3种类型；（4）科技创新与绿色发展协调性具有明显的空间溢出效应，长江经济带内相邻城市协调度的变换具有趋同特征。最后，提供了相关政策建议。

Abstract: Innovation is a pioneer driving force for development, and green development is the primary requirement of the Yangtze River Economic Belt Strategy. Taking 108 cities in Yangtze River Economic Belt as the objects, we construct a comprehensive evaluation system of scientific and technological innovation and green development. Using entropy method, coupling coordination degree model and the spatial Markov chain method, this paper analyzes the coupling degree, spatial-temporal distribution and correlation of scientific and technological innovation and green development in the Yangtze River Economic Belt from 2006 to 2016. The conclusions are as follows. Firstly, during the research period, the scientific and technological innovation and green development index of Yangtze River Economic Belt have generally increased, but the overall level is low which only appear to grow simultaneously after 2013. Secondly, the coupling degree and coordination index of scientific and technological innovation and green development are on an upward trend,while the spatial differentiation within the belt is obvious，and that in the Yangtze River Delta is markedly higher than that of other regions. Thirdly, The coordination of technological innovation and green development is clustered, showing a declining feature of “downstream＞midstream＞upstream”. Cities among lower coordination index can be classified into three types, namely “leading in technology innovation”, “leading in green development” and “balanced”. Besides, there exists significant spatial spillover effects in the coordination of scientific and technological innovation and green development. The transformation of the coordination degree in adjacent cities has similar characteristics. Finally, corresponding policy suggestions are provided.
