区域科技创新政策绩效比较研究——基于北京、上海、天津和重庆的实证研究

本研究基于DEA-Malmquist指数模型测算北京、上海、天津和重庆四个直辖市的区域科技创新政策绩效,结合实证以全要素生产率变动指数tfpch衡量政策绩效,并对tfpch及其他指数结果进行分解和说明。结果表明,在一期滞后的前提下,考察的四个直辖市区域科技创新政策绩效只有北京略有提升,另外三个城市均有小幅降低,政策效果尚不明显,但这并不代表政策无效,而可能是由不同城市相异的政策滞后效应带来的。就北京来看,区域科技创新政策绩效的提升主要来源于技术进步指数techch的提升,即技术进步有助于提升科技创新政策绩效。本研究一方面为城市创新建设提供一定借鉴,另一方面也为创新导向的城市改进方案设计和区域科技创新政策的立改废提供思路。

A Comparative Study of the Region Science and Technology Innovation Policies Performance:The Empirical Research Based on Beijing,Shanghai,Tianjin and Chongqing

Based on the DEA-Malmquist index model,this study calculates the regional science and technology innovation(STI)policies performance of Beijing,Shanghai,Tianjin and Chongqing.The research also explains the the total factor productivity change index tfpch and decomposition of the results based on empirical results.The results show that,in the case of one period delay,among four municipalities which were researched,the STI policies performance in Beijing has been improved slightly,and the other three cities have small decrease.The policy effects are not obvious,while it does not mean that the policy is ineffective.It may be just due to the different policy lag effects in different cities.The improvement of STI policies performance in Beijing mainly comes from the improvement of technology progress index techch,that is,technology progress helps to improve the performance of science and technology innovation policy.On the one hand,this study provides some references for the construction of cities;on the other hand,it also provides ideas for the improvement scheme design of innovation-orientated city construction and the establishment,revision and abolishment of regional STI policies.
