摘要
成渝地区双城经济圈是西部大开发的重要平台,提升成渝地区双城经济圈绿色创新效率,对于实现我国经济高质量发展具有重要意义.本文基于2005-2019年权威统计数据,采用SBM-DEA(Slacks Based Measure-Data Envelopment Analysis)模型、核密度模型和多元回归模型,分析成渝地区双城经济圈绿色创新效率、演变趋势及影响因素.研究发现,样本期间内成渝地区双城经济圈绿色创新效率整体偏低,不同城市绿色创新效率测度结果差异较大,呈现出“下降—波动—上升”变化的特征.从演变趋势看,成渝地区双城经济圈绿色创新效率存在一定的下行压力,城市群内部离散程度呈缩小趋势,《成渝城市群发展规划》的实施,使得城市群“双核”绿色创新的辐射扩散能力得到强化.从城市层面来看,成渝地区双城经济圈各城市绿色创新效率呈现出上升型、U型、倒U型和区间波动型4类演变轨迹.政府支持、开放程度显著影响成渝地区双城经济圈绿色创新效率,经济发展水平的促进作用不显著;要素扭曲的存在使得教育水平对区域绿色创新效率发挥抑制作用,产业结构对成渝地区双城经济圈绿色创新效率影响不显著.
Chengdu-Chongqing Economic Circle is an important platform for the development of western China.Improving its green innovation efficiency is of great significance to promotethe high-quality development of China’s economy.Based on statistical data from 2005 to 2019,this paper uses SBM-DEA(Slacks Based Measure-Data Envelopment Analysis)model,Kernel Density Estimation and regression model to explore the status,evolution trend and influencing factors of green innovation efficiency.It is found that the green innovation efficiency level of the double city economic circle is relatively low in the sample period,and the results of different cities are quite different,showing the characteristics of“fall-fluctuation-rise”.Look from green innovation efficiency trends,the green innovation efficiency has certain downward pressure,and the degree of dispersion within urban agglomerationshows a shrinking trend.The implementation of thedevelopment plan of double city urban agglomerationstrengthens the radiation diffusion ability of the green innovation ability of the“dual-core”urban agglomeration.From the urban level,the green innovation efficiency presents four types of evolution tracks:upward,U-shaped,inverted U-shaped and interval fluctuation type.Further,it is found that the government support and the degree of openness significantly affect the green innovation efficiency,while the promotion effect of economic development level is not significant.The existence of factor distortions makes the education level restrainingthe regional green innovation efficiency,while the industrial structure has no significant effect on the green innovation efficiency.
