京津冀绿色创新效率与环境规制关系研究——以高技术产业和高耗能产业为例

Research on the Relationship between Green Innovation Efficiency and Environmental Regulation in Beijing-Tianjin-Hebei Region——Take High-tech and Energy-intensive Industries as Examples

以高技术产业和高耗能产业为例,利用考虑非期望产出的超效率SBM模型测算了2009—2016年京津冀各城市高技术产业和高耗能产业绿色创新效率。在此基础上,用最小二乘法回归模型研究了京津冀绿色创新效率与环境规制的关系。结果表明:北京和天津高技术产业和高耗能产业绿色创新效率均高于河北各城市,河北省高耗能产业绿色创新效率高于高技术产业;高技术产业绿色创新效率与环境规制存在显著负相关关系,与对外开放度存在负向关系,与企业规模和研发强度存在正向关系;高耗能产业绿色创新效率与环境规制呈正相关关系,与对外开放度存在负向关系,与企业规模和研发强度存在正向关系。

Taking the high-tech industries and high energy-consuming industries as examples,green innovation efficiency of high-tech industries and energy-intensive industries in Beijing-Tianjin-Hebei region from 2009 to 2016 was measured by using super efficiency SBM model that considered undesired output.On this basis,the least square regression model was used to study the relationship between green innovation efficiency and environmental regulation in Beijing-Tianjin-Hebei region.The results show that the green innovation efficiency of Beijing and Tianjin is much higher than that of other cities in Hebei province.And the green innovation efficiency of high energy-consuming industries in Hebei province is higher than that of high-tech industries.Besides,the green innovation efficiency of high-tech industries is negatively correlated with environmental regulation,negatively correlated with openness,and positively correlated with enterprise scale and r&d intensity.The green innovation efficiency of high energy-consuming industries are positively correlated with environmental regulation,negatively correlated with openness,and positively correlated with enterprise size and r&d intensity.
