基于DEA的城市创新系统创新效率评价分析

Innovation Efficiency Evaluation Analysis of Urban Innovation Systems Based on DEA Methods

城市创新系统对促进城市创新活动的开展具有重要作用,对城市创新活动的创新效率进行评价具有重要现实意义。选取6个创新投入及产出的指标和30个省会城市及直辖市作为决策单元,利用DEA方法对30个城市的创新总体效率、技术效率、规模效率和饱和度作出评价,通过差额变量分析对4个非DEA有效的典型城市提出了对应的调整方案,并分地区对4种有效性进行了分析,最后提出了相应建议。

Urban innovation systems plays an important role in promoting urban innovation activity,it has an important and practical significance to evaluate the innovation efficiency of urban innovation activity.This paper selects 6 innovation input and output indexes and 30 provincial capital and municipalities as decision making units.It makes comments on overall efficiency,technical efficiency,scale efficiency and saturation of 30 cities innovation using DEA method.It puts forward corresponding adjustment scheme based on the analysis of difference variables through 4 representative urbans of the DEA ineffective,and makes detailed analysis on four effectiveness in various regions,and raises the corresponding proposal at the same time.
