提升长江经济带城市能源碳绩效水平是推动其绿色低碳转型的关键所在。论文运用NDDF-DEA法测度了2011—2019年长江经济带90个城市的能源碳绩效水平，并在理论分析数字普惠金融影响城市能源碳绩效内在机理的基础上，构建了非线性双向固定效应模型，系统考察了数字普惠金融与能源碳绩效之间的非线性关系。结果表明：数字普惠金融与长江经济带城市能源碳绩效之间呈“先抑制，后促进”的“U”型非线性关系，该结论在以全国互联网普及率作为工具变量和替换被解释变量等稳健性检验后依然成立；机制检验表明，数字普惠金融可以通过绿色技术创新、产业结构升级来推动能源碳绩效的提升；异质性分析显示，数字普惠金融对能源碳绩效的影响程度，在长江经济带不同区域、不同资源禀赋的城市之间仍存在一定差距。上述结论为新发展理念下数字普惠金融推动长江经济带城市绿色低碳转型与区域协调发展提供了参考和借鉴。

Improving the energy and carbon performance of cities in the Yangtze River Economic Belt is the key to promoting their green and low-carbon transformation.The energy carbon performance level of 90 cities in the Yangtze River Economic Belt from 2011 to 2019 was measured by the NDDF-DEA method,and on the basis of theoretical analysis of the internal mechanism of digital inclusive finance affecting urban energy carbon performance,a nonlinear two-way fixed effect model was constructed to systematically investigate the nonlinear relationship between digital inclusive finance and energy carbon performance.The results show that digital inclusive finance has a U-shaped nonlinear relationship between first inhibiting and then promoting the energy carbon performance of cities in the Yangtze River Economic Belt,and the conclusion is still valid after the robustness test of taking the national Internet penetration rate as the instrumental variable and replacing the explanatory variable.Heterogeneity analysis shows that there is still a gap between cities in different regions and different resource endowments in the Yangtze River Economic Belt on the impact of digital inclusive finance on energy carbon performance.The above conclusions provide a reference for digital inclusive finance to promote the green transformation and regional coordinated development of cities in the Yangtze River Economic Belt under the new development concept.
