【摘要】 运用DEA方法,测度2009—2017年30个省份规模以上工业企业的绿色技术创新效率;并从政府行为视角出发,重点研究环境规制和政府支持对绿色技术创新效率的影响。结论表明:(1)绿色技术创新效率低于传统技术创新效率,纯技术效率低下是导致综合技术效率不高的主要原因;(2)环境规制与绿色技术创新效率之间存在"先抑制后促进"的"U"型关系。随着环境规制强度的提高,绿色技术创新效率呈现先下降后上升的趋势;(3)政府科技支持不仅本身对绿色技术创新效率有显著促进作用,而且它还会在环境规制对绿色技术创新效率的促进过程中起到正向调节作用;(4)政府环保支持对绿色技术创新效率的促进作用不明显,正向调节作用也不显著。基于此,要进一步调整和完善环境规制作用;继续加大政府的科技支持力度;扩大环保支出规模,完善环保支出结构。更多还原

【Abstract】 The DEA method is used to measure the green technology innovation efficiency of industrial enterprises above designated size in 30 provinces from 2009 to 2017. From the perspective of government behavior,the focus of the research is the impact of environmental regulation and government support to the efficiency of green technology innovation. The conclusions are manifold. Firstly,the innovation efficiency of green technology is lower than that of traditional technology,and low pure technical efficiency is the main cause for low comprehensive technical efficiency. Secondly,there is a u-shaped relationship between environmental regulation and green technology innovation efficiency. With the strength of environmental regulation increasing,the efficiency of green technology innovation tends to decline first and then rise.Thirdly,governmental science and technology support not only significantly promotes the efficiency of green technology innovation, but also positively moderates the process of environmental regulation promoting the efficiency of green technology innovation. And fourthly,government environmental protection support does not play an obvious role in promoting the efficiency of green technology innovation,nor is its positive moderating role significant. Based on the above,the government should further adjust and improve its role of environmental regulation,continue to increase its science and technology support,expand spending on environmental protection,and perfect the structure of expenditure on environmental protection.更多还原
