基于两阶段效率视角的城市创新能力测算——来自20个典型城市的实证研究

A Study on the Measurement and Optimization of Urban Innovation Capability from the Perspective of Two-stage Efficiency

创新成为城市发展的重要驱动力,城市创新能力的本质是在动态环境下有效率地配置创新资源,提高创新绩效。基于效率视角,构建了城市创新能力的两阶段效率模型,并选取国内20个城市进行实证研究。在创新能力效果评价的基础上,借助非参数的超效率DEA方法对创新能力进行了效率评价,并对两种评价结果进行了对比分析。结果表明:创新效率与投入产出规模无关;城市创新能力存在显著的阶段性差异,在创新成果产出和转化两个阶段表现出不同的效率。最后,提出了优化对策。

By referring to the competence theory of firms in Management ,this paper points out the essence of Urban Inno-vation Capability (UIC) lies in the efficiency of resource allocation in innovation activities ,then sets a two-stage efficiency model and adopts Super-efficiency DEA to measure the efficiency of UIC in China comparing with its effect measurement . The result shows that the efficiency of UIC does not depend on the scale but the coordination of input-output and most cit-ies have sharply different efficiency in output stage and commercialization stage of Scientific and technological achieve-ments .Finally ,the paper puts forward relevant policy recommendations .
