长江经济带科技创新效率及影响因素研究

The Technology Innovation Efficiency and Influencing Factors of the Yangtze River Economic Belt

将科技创新过程分为技术创新和经济产出两个阶段,选取长江经济带11个省市2009—2019年的面板数据,基于超效率DEA-Tobit对该区域测度两阶段科技创新效率并对其影响因素进行分析。研究结果表明;(1)长江经济带科技创新效率总体上有所提升,但各省市之间技术创新效率和经济产出效率存在显著差异,区域间差异随时间演进逐渐减少;(2)政府支持、人力资本水平等指标对技术创新效率和经济产出效率有着不同方向的影响。最后基于研究结论,提出提升长江经济带科技创新效率的政策建议。

This paper dividesthe process of technology innovation into two stages: technological innovation and economic output. The panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2009 to 2019 were selected to analyze the two-stage scientific and technological innovation efficiency and its influencing factors in this region based on the super-efficiency DEA-Tobit. The results show that:(1) The technological innovation efficiency of the YREB has been improved in general, but there are significant differences in technological innovation efficiency and economic output efficiency among provinces and cities, and the regional differences gradually decrease with time.(2) Government support and human capital level have different effects on technological innovation efficiency and economic output efficiency. Finally, based on the research conclusions, some policy suggestions are put forward to improve the efficiency of S&T innovation in the Yangtze River Economic Belt.
