基于SBM-Tobit模型的京津冀城市生态文明建设效率研究

Research on the Efficiency of Beijing-Tianjin-Hebei City Ecological Civilization Construction Based on SBM-Tobit Model

生态文明建设是中华民族实现跨越式发展的战略选择,京津冀生态文明建设事关全国生态文明建设成败。为指导京津冀城市生态文明建设,论文首先采用超效率SBM模型,基于非期望产出视角,分析了京津冀城市近10年的生态文明建设效率,结果显示京津冀城市生态文明建设效率总体向好但城市间存在较大差距;进一步采用Tobit模型,分析影响生态文明建设效率的关键因素,探讨提高京津冀城市生态文明建设效率的途径。

The construction of ecological civilization is a strategic choice for the Chinese nation to achieve leap-forward development.The construction of ecological civilization in Beijing-Tianjin-Hebei is related to the success or failure of national ecological civilization construction.In order to guide the construction of Beijing-Tianjin-Hebei urban ecological civilization,this paper firstly uses the super-efficient SBM model to analyze the efficiency of ecological civilization construction in the Beijing-Tianjin-Hebei city in the past 10 years based on the perspective of non-expected output,the results show that the efficiency of urban ecological civilization construction in Beijing,Tianjin and Hebei is generally good,but there is a big gap between cities;the Tobit model is further used to analyze the key factors affecting the efficiency of ecological civilization construction,and to explore ways to improve the efficiency of urban ecological civilization construction in Beijing,Tianjin and Hebei.
