【摘要】：文章以湖北省12个地级市作为决策单元,构建熵权法结合超越对数形式的随机前沿模型,测算绿色创新效率并对其影响因素进行了分析。结果表明:(1)2007—2014年湖北省城市绿色创新平均效率为0.307,仍有近70%提升空间;城市间差异显著,武汉、宜昌、襄阳优势明显。(2)科技人员和科技支出作为创新资源投入对于湖北省绿色创新产出有着显著的正向作用,科技人员具有更高的产出弹性;而环境污染指数对于绿色创新存在着明显的抑制作用。(3)环境规制强度与绿色创新效率呈"倒U"型关系,"波特假说"中合理的环境规制的重要性也得到印证;(4)区域开放程度对湖北省绿色创新效率具有负向作用,教育水平提高和产业结构优化升级有利于湖北省绿色创新效率的提高。
[Abstract]:Taking 12 prefectural cities in Hubei Province as decision making units, this paper constructs a stochastic frontier model based on entropy weight method and transcendental logarithm to measure the green innovation efficiency and analyze its influencing factors.The results show that the average efficiency of urban green innovation in Hubei Province from 2007 to 2014 is 0.307, and there is still nearly 70% room for improvement.Xiangyang has obvious advantage. 2) Science and technology personnel and science and technology expenditure as innovation resource input have significant positive effect on green innovation output of Hubei province, and scientific and technological personnel have higher output elasticity;The environmental pollution index has a significant inhibitory effect on green innovation. (3) the relationship between environmental regulation intensity and green innovation efficiency is "inverted U", and the importance of reasonable environmental regulation in the Porter hypothesis has also been confirmed.The degree of openness has a negative effect on the efficiency of green innovation in Hubei Province.The improvement of education level and the optimization of industrial structure are beneficial to the improvement of green innovation efficiency in Hubei Province.
