Carbon neutrality is an important environmental management tool to deal with the global greenhouse effect. Addressing climate change is an important starting point for promoting the high-quality development of China's economy and the construction of ecological civilization, as well as an important area for participating in global governance and adhering to multilateralism. In this paper, from the perspective of carbon neutrality, taking China's Jiangsu Province as an example, the super-efficiency DEA model is selected to measure the level of ecological efficiency in Jiangsu, and on this basis, the Tobit model is used to verify the main factors affecting regional ecological efficiency. The results are as follows: (1) The regional eco-efficiency in Jiangsu shows a trend of decreasing from south to north, with obvious phenomenon of "club convergence", with significant spatial correlation and agglomeration. (2) The industrial structure is negatively related to the regional eco-efficiency of Jiangsu regions; Energy consumption structure has a positively impact in southern Jiangsu,but negatively in central and northern Jiangsu; FDI has a positively impact in central and northern Jiangsu, but negatively in southern Jiangsu; Regional economic development has a positively impact in southern and northern Jiangsu, but negatively in central Jiangsu; The progress in the technological level has positive effects on the eco-efficiency of all regions of Jiangsu. The final paper puts forward some suggestions based on the carbon neutral target Provide theoretical reference for achieving the goal of carbon neutrality.
碳中和是应对全球温室效应的重要环境管理工具。应对气候变化是推动中国经济高质量发展和生态文明建设的重要起点，也是参与全球治理、坚持多边主义的重要领域。本文从碳中和的角度出发，以中国江苏省为例，采用超效率 DEA 模型测度江苏省的生态效率水平，并在此基础上运用 Tobit 模型验证了影响区域生态效率的主要因素。结果表明：（1）江苏省区域生态效率呈现由南向北递减的趋势，具有明显的“俱乐部趋同”现象，具有显著的空间相关性和集聚性。（2）产业结构与江苏省各区域的区域生态效率呈负相关；能源消费结构在苏南地区对区域生态效率有正向影响，而在苏中和苏北地区则有负向影响；FDI 在苏中和苏北地区对区域生态效率有正向影响，而在苏南地区则有负向影响；区域经济发展在苏南和苏北地区对区域生态效率有正向影响，而在苏中地区则有负向影响；技术水平的进步对江苏省各区域的生态效率均有正向影响。最后，本文根据碳中和目标提出了一些建议，为实现碳中和目标提供了理论参考。
