摘要
立足于探讨国家高新区设立对属地省域绿色创新水平的实际驱动效应。首先,从理论层面揭示了高新区设立驱动绿色创新水平提升的3个作用机理,即集聚驱动、结构驱动和规模约束驱动;其次,构建了衡量区域绿色创新水平的评价指标体系,在此基础上,综合应用基于非期望产出的SBM-DEA模型和核密度估计,对中国区域绿色创新水平的基本格局及区域差异演变特征进行探讨。结果表明,中国区域绿色创新效率呈波动上升态势,但存在明显的空间差异,核密度估计结果也显示中国绿色创新水平省域差异日益扩大,马太效应日趋明显;最后,以2006-2015年中国内地30个省市面板数据为例,采用面板Tobit模型验证高新区设立对区域绿色创新水平的影响。实证结果显示,国家高新区的设立对区域绿色创新水平具有显著驱动效应,但高新区发挥实际作用还依赖于经济基础,进一步分析表明,高新区设立对东部省市绿色创新水平的驱动效果显著,而对中西部地区没有明显的驱动作用,最后据此提出相应启示与对策。
Aimed at evaluating the actual driving effect of National High-tech Zones(NHZs),we construct the mechanisms of agglomeration drive,structure drive and scale constraint from the theoretical level.we then used the SBM-DEA model based on undesired output and the Kernel Density Estimation to describe the level of regional green innovation in China.The results show that China's regional green innovation efficiency is fluctuating and has an obvious spatial differences.Besides,the regional gap is increasing and the"Matthew benefit"becomes more and more obvious.We finally empirically test the impact of the establishment of NHZs on regional green innovation based on the panel Tobit model.Results show the significant driving effect exists,while the actual effect depends on the economic situation and regional differences exist.Some countermeasures are given in the last part.
