The Impact of Low-Carbon Pilot Provincial and Municipal Construction Policy on Agricultural Carbon Emission Efficiency——Based on SBM-DEA Model and SCM Model

Under the current trend of global warming, the issue of agricultural carbon emissions has become one of the key challenges to global sustainable development. Improving agricultural carbon emissions is regarded as an important way to reduce the carbon intensity of agriculture and help achieve the goal of “double carbon”. Based on the panel data of 31 provinces in China from 2000 to 2020, this study measures the agricultural carbon emissions of each region, and then analyzes the regional differences in the efficiency of agricultural carbon emissions by using the SBM-DEA model. Finally, the actual impacts of low-carbon pilot policies on the efficiency of agricultural carbon emissions were systematically evaluated through the synthetic control method. The results of the study show that the implementation of the low-carbon pilot provinces and cities construction policy significantly improves the agricultural carbon emission efficiency in most of the pilot provinces, which verifies the positive promotion effect of the policy on agricultural carbon emission efficiency.
