摘要
基于我国工业行业的面板数据,运用DEA模型测算了各行业的绿色技术创新效率,并对绿色技术研发以及绿色技术转化两个阶段的效率进行了比较分析,最后运用Tobit模型对绿色技术创新效率的影响因素进行了实证研究。研究发现:中国工业行业绿色技术创新效率整体呈现上升的发展趋势,但各行业间存在较大差距;平均企业规模、市场化程度、对外开放程度及环境规制强度等是促进绿色技术创新效率提升的主要因素;技术环境对绿色技术创新效率的影响主要作用于绿色技术研发阶段,而绿色技术转化阶段则主要受市场环境和政策环境的影响。进一步提升绿色技术创新效率,需要加大绿色技术创新投入,优化资源配置,营造良好的创新环境。
Based on the panel data of China's industrial industry,this paper uses the DEA model to measure the efficiency of green technology innovation in various industries,compares and analyzes the efficiencies at the two stages of green technology R&D and the conversion of green technology.Finally,it exploits the Tobit model to evaluate the efficiency of green technology innovation in its empirical study on the influencing factors.The research finds that the overall efficiency of green technology innovation in China's industrial industry is on the rise with yet great gaps between industries,that factors such as average enterprise size,degree of marketization,degree of opening to the outside world,and intensity of environmental regulations are the main forces that promote the improvement of the efficiency of green technology innovation,and that the impact of the technology environment on the efficiency of green technology innovation works mainly at the stage of the green technology R&D,while the green technology transformation stage is mainly affected by the market environment and policy environment.To further improve the efficiency of green technology innovation,we need to increase investment in green technology innovation,optimize resource allocation,and create a good environment for innovation.
