长江经济带科技创新效率和科技创新支撑下的经济发展效率测度分析

文章以长江经济带的11个省市为研究对象,基于PCA-SE-DEA理论的组合模型,对其科技创新效率进行定量检测,分析影响其发展进程的要素体系,并重点对长江经济带科技创新效率进行收敛检测,分析其影响因素及成因.同时,基于C-D生产函数对科技创新与经济发展因素在长江经济带当中的关联效应进行分析.研究结果显示:长江经济带科技创新效率目前未能达到我国平均水准;位于长江边缘地带的各省市在科技创新效率方面呈现出地区差异性,并且这一差异呈现扩大态势;在影响成因当中,区域产业结构优化升级对长江经济带科技创新效率影响最大,科技投资、科技输出以及科技环境对于地区经济的良好发展尤为关键.因此,长江经济带需要整体调整和规划,构建协调机制,形成流域整体创新创业的良好运作系统,全方位提升科技创新效率.

Measurement and analysis of economic development efficiency under the support of scientific and technological innovation efficiency and scientific and technological innovation in the Yangtze River Economic Belt

Taking 11 provinces and cities in the Yangtze River Economic Belt as the research object, based on the combined model of PCA-SE-DEA theory, this paper quantitatively tests the scientific and technological innovation efficiency, analyzes the factor system affecting its development process, focuses on the technological innovation efficiency of the Yangtze River Economic Belt, and conducts convergence testing and analyzes its influencing factors and causes. At the same time, based on the C-D production function, the paper analyzes the correlation between technological innovation and economic development factors in the Yangtze River Economic Belt. The research results show that:the efficiency of technological innovation in the Yangtze River Economic Belt has not reached the average level in China at present; the provinces and cities in the Yangtze River Economic Belt show regional differences in the efficiency of technological innovation, and this difference shows an upward trend. Among the influencing factors, the optimization and upgrading of regional industrial structure has the greatest impact on the technological innovation efficiency of the Yangtze River Economic Belt. Among them, investment in science and technology, output of science and technology and environment of science and technology are particularly important for the good development of regional economy. The supporting efficiency of science and technology innovation for economic development is generally effective, with obvious regional differences. Therefore, the Yangtze River Economic Belt needs to adjust and plan as a whole, build a coordination mechanism, realize a good operation system of overall innovation and entrepreneurship in the basin, and improve the efficiency of technological innovation in an all-round way.
