珠三角9市创新产出能力综合评价与创新效率DEA分析

A Comprehensive Evaluation of Innovation Output Capability and a DEA Analysis of Innovation Efficiency of the Nine Cities in the Pearl River Delta

采用熵值法对2011-2019年珠三角9市的创新产出做综合评价,并在此综合指标值的基础上引入时滞效应,假设滞后期为1年,利用多个DEA模型对2011-2019年珠三角9市的创新效率进行联合测算。研究结果表明:城市创新能力与创新效率均有强弱差距较大,且整体表现出“东强西弱”的特征;部分城市创新投入出现较大冗余,可适当优化创新活动的资源配置;9市创新效率发展不充分、不均衡,技术进步是全要素生产率提升的主要原因。

The entropy method is used to comprehensively evaluate the innovation output of the 9 prefecture-level cities in the Pearl River Delta from 2011 to 2019,and the time lag effect is introduced on the basis of this comprehensive index value,assuming that the lag period is 1 year and using multiple DEA models to jointly calculate the innovation efficiency of the 9 cities from 2011 to 2019.The research results show that:(1)there is a large gap between the strengths and weaknesses in urban innovation capabilities and innovation efficiency among the cities,and the overall performance is"strong in the east and weak in the west";(2)there is a large redundancy in innovation investment in some cities,which can be appropriately optimized by resource allocation for innovation activities;(3)there exists insufficient and uneven development of innovation efficiency in the 9 cities,and technological progress is the main cause for the increase in total factor productivity.
