黄河经济带科技创新水平测度研究——基于DEA、SBM

运用数据包络分析中的CCR模型、BCC模型对黄河经济带11个省市科技创新的相对效率进行测度;运用SBM模型对变量松弛的测度结果进行修正,并对非DEA有效的决策单元进行目标改进;运用SBM超效率模型解决了具有相同效率值的不同省市的排序问题。得出结论如下:北京、天津、山东三省市表现出较高的技术有效性,其他8个省区(河北、山西、内蒙、河南、陕西、甘肃、青海、宁夏)均表现出一定程度的技术相对无效和规模相对无效;非SBM有效的决策单元主要集中在黄河中上游地区;黄河经济带的科技资源配置效率不高,在一定程度上表现为非SBM有效区域存在比较普遍的科技投入冗余现象。

Research on Measurement of Science and Technology Innovation Level of Economic Zone in Yellow River: Based on DEA and SBM

This paper measures the efficiencies of science and technology innovation of 11 provinces in economic zone in Yellow River by CCR model and BCC model,and utilizes SBM model to modify the measurement results of slack variable and improve the efficiencies of non-DEA-effective units,and uses SBM super-efficiency model to solve the problem of ordering provinces with the same efficiency.The conclusions are as follows:the technical effectiveness of Beijing,Shandong and Tianjin are high;the non-SBM-effective decis...
