我国6大城市群高新区创新经济效率评价——基于DEA模型和Malmquist指数分析

Evaluation on Innovation Efficiency of High-Tech Zones in 6 Major Urban Agglomerations in China——Based on DEA Model and Malmquist Index Analysis

国家自主创新示范区作为区域创新的重要节点和产业,近些年出现以城市群高新区为基本设立单元的趋势。本文运用DEA方法和Malmquist指数法,基于我国6大城市群14个省市高新区2013~2017年的面板数据,分别从区域和城市群两个视角,对其高新区创新效率进行静态和动态的研究。结果表明:6大城市群中高新区创新效率整体保持上升。从区域角度来看,创新效率增长呈现"西高东低"的态势。从城市群角度来看,城市群呈现内部创新效率不均衡。通过对区域及城市群创新全要素生产率进行分解发现,技术效率变化是影响创新效率的主要因素,提升纯技术效率和规模效率成为创新效率新的增长点。最后,依据结论提出相应的政策建议,为进一步提升高新区创新能力建设提供参考。

As an important node and industry of regional innovation,national independent innovation demonstration zone has shown a trend of setting up units based on urban high-tech zones in recent years.In this paper,DEA method and Malmquist index method are used to conduct static and dynamic research on the innovation efficiency of high-tech zones in 14 provinces and cities of China’s six major urban agglomerations from the perspective of regions and urban agglomerations respectively,based on the panel data from 2013 to 2017.The results show that the innovation efficiency of high-tech zones in the six major urban clusters keeps increasing.From the regional perspective,the growth of innovation efficiency shows a trend of"high in the West and low in the East".From the perspective of urban agglomeration,the internal innovation efficiency of urban agglomeration is unbalanced.Through the decomposition of innovation total factor productivity in regional and urban agglomeration,it is found that the change of technical efficiency is the main factor affecting innovation efficiency,and the improvement of pure technical efficiency and scale efficiency has become a new growth point of innovation efficiency.Finally,according to the conclusion,corresponding policy Suggestions are put forward to provide reference for further improving the innovation capacity construction of high-tech zones.
