以京津冀地区的13个城市为研究对象,在考虑环境负效应的影响下,运用非期望产出SBM模型对13个城市的循环经济效率进行了测度分析,并采用Tobit分析法对影响循环经济效率的因素进行了回归分析。结果显示:京津冀地区的循环经济效率呈“N”型上升态势,年增长率为2.45%;北京和天津的循环经济效率一直处于0.872以上的良好水平,其他城市的循环经济效率较低;经济、社会、环境因素对地区循环经济效率具有不同的影响且其作用机理存在差异。
Taking the 13 cities in Beijing, Tianjin and Hebei as the research objects, taking into account the negative effects of the environment, the non-expected output SBM model was used to measure the recycling economy efficiency of 13 cities. Tobit analysis was used to analyze the influence of circulation Economic efficiency of the regression analysis of the factors. The results show that the efficiency of circular economy in Beijing-Tianjin-Hebei region has been rising up to “N”, with an annual growth rate of 2.45%. The recycling economy in Beijing and Tianjin has been at a good level of above 0.872. The recycling economy in other cities is more efficient Low; economic, social and environmental factors on the efficiency of circular economy have different effects and its mechanism of action there are differences.
