中国市域技术创新与绿色发展耦合协调演变分异

Evolution and Differentiation of Coupling Coordination Between Technological Innovation and Green Development in Chinese Cities

基于中国283个地级及以上城市的样本数据,运用耦合协调模型、Dagum基尼系数等方法,揭示中国技术创新与绿色发展耦合协调度的时空演变特征、差异性事实。研究发现:(1)技术创新与绿色发展耦合协调度整体上在逐年缓慢增长,主要得益于技术创新的不断提升。东北、华北、华南、华东、西南地区为中度耦合协调,华中和西北处于低度耦合协调,仅有东北呈现逐年下降趋势。城市规模和耦合协调度成正比,不同城市规模间表现出较大差异。(2)耦合协调度在地区间的差异占整体差异的48.7%,尤其是华东、华南与西北、西南、东北之间。城市规模间的差异占整体差异的84.18%,同一城市规模内部差异较小。基于系统论视角,研究结论为落实创新驱动经济绿色发展战略提供了可供参考的政策支撑。

Based on the sample of 283 cities in China,this paper uses the coupling coordination model,Dagum Gini coefficient to reveal the spatial-temporal characteristics of the coupling coordination degree between technological innovation and green development in China,and its differential facts.Results show that:1)Owing to the continuous improvement of technological innovation,the coupling coordination degree between technological innovation and green development of Chinese cities is slowly increasing annually.Northeast China,North China,South China,East China and Southwest China are areas with moderate coupling coordination,while Central China and Northwest China are areas with low coupling coordination.Only Northeast China shows a downward trend on the coupling coordination degree.The city size is positively correlated with the coupling coordination degree,and such relationship evinces great differences among different city sizes.2)The difference of coupling coordination degree among regions accounts for 48.7% of the overall difference,especially the difference between East China,South China and Northwest,Southwest and Northeast China.The difference among different city sizes accounts for 84.18% of the total difference,whereas that within the same city size is small.This paper studies the coupling coordination between technological innovation and green development in Chinese cities from the perspective of system theory,whose conclusions provide policy support for the implementation of green development strategy of innovation driven economy.
