长三角区域一体化背景下安徽省城市减污降碳协同治理研究

Research on the Collaborative Governance of Pollution Reduction and Carbon Reduction in Cities in Anhui Province under the Background of Yangtze River Delta Regional Integration

摘要: 二氧化碳和碳排放同根同源，相关性非常大，碳排放和大气污染进行协同治理非常必要。基于长三角区域一体化的背景，以安徽省16个地级市为研究对象，将二氧化碳和大气污染物SO₂作为非期望产出，运用超效率SBM模型测算2011~2019年间安徽省城市全要素绿色生产效率，以及二氧化碳和大气污染物的减排潜力。实证结果显示，安徽省共有13个城市的绿色全要素生产率均值低于1，碳减排和大气污染减排潜力接近30%，具有较大的减排空间。运用标杆管理方法，根据各城市碳减排和大气污染减排潜力情况，确定追赶对象和改进路径。马鞍山、淮南、淮北、铜陵和阜阳等城市为安徽省碳减排和大气污染减排协同治理的重点城市。马鞍山、淮南、淮北、铜陵按照“常州–合肥–南通”路径去改进。阜阳选择“金华–丽水”的路径。芜湖选择“杭州–南京–南通–上海”的路径。安庆和蚌埠则选择“盐城–南通”的路径。

Abstract: Carbon dioxide and carbon emissions have the same root and the correlation is very large, so it is necessary to conduct collaborative treatment of carbon emissions and air pollution. Based on the background of the regional integration of the Yangtze River Delta, 16 prefecture-level cities in Anhui Province were taken as the research object, carbon dioxide and air pollutant SO₂ were taken as the non-expected outputs, and the all-factor green production efficiency and emission reduction potential of carbon dioxide and air pollutants in Anhui Province during 2011~2019 were calculated by using the super-efficiency SBM model. The empirical results show that the average green total factor productivity of 13 cities in Anhui Province is lower than 1, and the carbon emission reduction and air pollution emission reduction potential is close to 30%, which has a large space for emission reduction. Using benchmarking management method, according to the carbon emission reduction and air pollution reduction potential of each city, the catch-up object and improvement path are determined. Ma’anshan, Huainan, Huaibei, Tongling and Fuyang are the key cities in Anhui Province to reduce carbon emission and reduce air pollution. Ma’anshan, Huainan, Huaibei and Tongling will be improved according to the “Changzhou-Hefei-Nantong” path. Fuyang chose the path of “Jinhua-Lishui”. Wuhu chose the path of “Hangzhou-Nanjing-Nantong–Shanghai”. Anqing and Bengbu chose the path of “Yancheng-Nantong”.
