摘要: 长江经济带发展战略的深入实施离不开科技创新与绿色发展的协调发展和共同进步。基于城市群视域,采用熵权法、超效率SBM模型、耦合协调度模型以及Tobit模型等方法,从多维度视角探讨2010~2019年长江经济带三大城市群85个城市科技创新与生态效率的耦合协调关系及其时空演变特征,并对二者耦合协调度的主要影响因素进行分析。结果表明:(1)长江经济带整体科技创新水平呈平稳上升趋势,生态效率水平呈降-升-降-升的“W”型变动趋势。科技创新与生态效率耦合协调度呈先升后降的倒“U”型波动上升趋势,且三大城市群空间差异性明显,呈现长三角城市群>长江中游城市群>成渝城市群的空间分布格局;(2)整体耦合协调发展水平存在显著的空间自相关特征,且多数城市表现为低低集聚,其中长三角城市群呈显著的“东高西低”型空间集聚特征,长江中游城市群与成渝城市群空间集聚特征不显著;(3)经济发展水平、劳动力集聚、对外开放程度以及产业结构对整体耦合协调水平有显著正向影响。基于以上结论,提出加大长江经济带生态环境保护力度、重视区域发展异质性、引进培育创新人才以及积极开展对外开放交流等政策建议。

Abstract: The in-depth implementation of the Development Strategy of the Yangtze River Economic Belt cannot be separated from the coordinated development and common progress of scientific and technological innovation and green development. Based on the perspective of urban agglomeration, taken 85 cities in the three major urban agglomerations of the Yangtze River Economic Belt from 2010 to 2019 as the research object, employed the entropy weight method, the super-efficiency SBM model, the coupling coordination degree model and the Tobit model, discussed the coupling coordination relationship and spatial-temporal evolution characteristics between scientific and technological innovation and ecological efficiency, and analyzed the key impact factors of coupling coordination degree. The results showed that: (1) From 2010 to 2019, the overall scientific and technological innovation level of the Yangtze River Economic Belt presented a steady rising trend, while the variation trend of the ecological efficiency level exhibited a W-shaped with a “descending - ascending - descending - ascending” feature. The coupling coordination degree of scientific and technological innovation and ecological efficiency showed a fluctuating upward trend with an inverted U-shaped pattern. The spatial heterogeneity between the three major urban agglomerations were significant, which exhibited that the Yangtze River Delta urban agglomeration > the middle reaches of the Yangtze River urban agglomeration > the Chengdu-Chongqing urban agglomeration. (2) There was a significant spatial autocorrelation feature between the overall coupling and coordinated development level, and most cities showed low and low agglomeration. The Yangtze River Delta urban agglomeration showed a significant “high in the east and low in the west” spatial agglomeration , while the middle reaches of the Yangtze River urban agglomeration and Chengdu-Chongqing urban agglomeration had no significant spatial agglomeration characteristics.(3) The level of economic development , the agglomeration of the labor force , the opening-up degree and the industrial structure had a significant positive impact on the overall coupling coordination level of the Yangtze River Economic Belt. Based on the above conclusions, this study puts forward suggestions for strengthening the ecological environment protection of the Yangtze River Economic Belt, emphasizing the heterogeneity of regional development, introducing and cultivating innovative talents, and actively carrying out open exchanges with the outside world.
