基于DEA的京津冀区域协同发展动态效度评价

The Dynamic Validity Evaluation of Cooperative Development in Beijing-Tianjin-Hebei Based on DEA

采用数据包络分析(DEA)模型测度京津冀协同发展的动态效度,并分析导致三地协同度差异的原因。研究结果表明,京津冀地区协同发展效度并没有达到最优,但协同度总体效率越来越好;北京、天津的协同度大于河北;京津冀三地的投入要素使得产出最大化,但投入与产出比例没有达到最优。最后,依据京津冀协同效度和发展定位提出了相应的对策建议。

Data Envelopment Analysis（DEA）is used in the paper to measure the validity of cooperative development in Beijing-Tianjin-Hebei and analyzes the reasons for the differences in the three areas.The research indicates the validity of cooperative development in Beijing-Tianjin-Hebei has not been achieved optimally,but overall efficiency of cooperative degree has been better and better.Cooperative degree between Beijing and Tianjin is greater than Hebei Province.Factor inputs from Beijing-TianjinHebei contribute to maximum output but input and output ratio has not been achieved optimally.At last,based on the validity and orientation of cooperative development in Beijing-Tianjin-Hebei,the paper proposes corresponding suggestions.
