    摘要:

    严峻的雾霾污染已经成为当下长江经济带生态一体化发展重大阻碍之一。运用三阶段DEA模型对长三角27个城市2014~2019年雾霾治理效率进行研究。结果表明:(1)三阶段DEA模型可有效剔除环境因素和随机误差的影响,真实反映长三角雾霾治理效率水平,第一和第三阶段综合效率差异主要来源于环境因素和随机误差因素对纯技术效率的影响。(2)绝大数城市处于规模收益递增阶段,说明扩大雾霾治理投入规模有助于提升雾霾治理效率。(3)2014~2019年长三角城市雾霾治理效率整体偏高且呈现W型变化趋势,城际差异显著。(4)人均GDP和第二产业占比增加改善了雾霾治理效率,而人口规模与城镇化率则对雾霾治理效率有负效应。基于此,建议进一步提高长三角城市雾霾治理效率水平,推进长江生态一体化发展,应加大技术创新力度,创建多元化雾霾治理资金投入模式,强化长三角城市协同治理水平。

    Abstract:

    In response to the severe haze pollution has become one of the major obstacles to the ecological integration development of the Yangtze River Economic Zone at presenta three-stage DEA model was used to study the haze management efficiency of 27 cities in the Yangtze River Delta from 2014 to 2019. The study shows that (1)Three-stage DEA model can effectively eliminate the effects of environmental factors and random errors, and can truly reflect the level of haze control efficiency in the Yangtze River Delta, and the difference between the integrated efficiency in the first and third stages is caused by environmental factors and random error factors affecting the pure technical efficiency. (2) The vast majority of cities are in increasing returns to scale, indicating that the improvement of haze control efficiency can be achieved by expanding the scale of haze control inputs.(3) The overall efficiency of haze control in Yangtze River Delta cities from 2014 to 2019 is high and shows a W-shaped change trend with intercity differences. (4) The increase in real GDP per capita and the share of secondary industry have positive effects on improving haze control efficiency, while the population size and urbanization rate have negative effects. Based on this, to further improve the level of haze management efficiency in Yangtze River Delta cities and promote the integrated ecological development of Yangtze River, we should increase technological innovation, create a diversified haze management funding model, and strengthen the level of collaborative management in Yangtze River Delta cities.
