碳交易能否缩小城乡收入差距?

Can Carbon Trading Narrow Urban-Rural Income Disparity?

如何缩小城乡收入差距是实现全体人民共同富裕的重大挑战。基于碳交易影响城乡收入差距的内在逻辑,运用中国2010-2019年208个样本城市数据,采用双重差分法实证检验碳交易对城乡收入差距的影响及作用机制。研究发现:碳交易能显著缩小城乡收入差距,该影响主要通过提高农村居民收入实现;碳交易缩小城乡收入差距的作用在不同类型的城市具有显著的异质性,对碳排放强度高、城市化水平低和煤炭依赖度高的城市缩小效应更为明显。研究将碳交易与城乡收入差距纳入统一框架,提出碳交易的收入分配效应,为实现“双碳战略”与共同富裕两大目标提供证据支持和建议参考。

As a significant challenge,how to narrow urban-rural income disparity is an important issue in achieving China's Model of Modernization for Common Prosperity.We explore the intrinsic logic of the impact of carbon trading on urban-rural income disparity,utilizing data from 208 sample cities in China from 2010 to 2019 and employing a differences-in-differences approach to empirically examine the effects and mechanisms of carbon trading on urban-rural income disparity.The study findings indicate that carbon trading can significantly reduce the income disparity,with the effect mainly being realized through increased rural residents' income.The effect of carbon trading in narrowing the income gap between urban and rural areas is significantly heterogeneous in different types of cities,and the narrowing effect on cities with high carbon emission intensity,low urbanization level and high coal dependence is more obvious.By integrating carbon trading and urban-rural income disparity within a unified framework,we innovatively propose the income distribution effect of carbon trading to provide reference for achieving the two goals of “Dual Carbon Strategy” and common prosperity.
