摘要
【目的】作为一场经济社会系统性变革,低碳能源转型将不可避免的对公平、收入等社会问题产生冲击。探究城市低碳能源转型对收入不平等的影响,可为协调经济社会低碳转型和缩小收入差距提供有益的经验启示。【方法】本文以2007—2020年281个地级市的面板数据为研究样本,通过建立多维度指标体系测算了城市低碳能源转型指数,同时,基于2109个区县的夜间灯光数据测度出了城市不同收入群体间的收入不平等程度,然后,从理论模型和实证分析两个层面考察低碳能源转型与收入不平等的内在关系。【结果】(1)低碳能源转型能够显著缓解收入不平等,转型指数每提高一个标准差,收入不平等降低约6.1%。(2)机制分析表明,低碳能源转型会通过技能偏向型技术进步和劳动力技能结构升级影响收入不平等,而低碳能源转型对收入不平等的缓解作用主要来源于其对劳动力技能结构升级的提升作用。(3)异质性分析发现,低碳能源转型对收入不平等的影响存在区域和城市特征异质性。(4)通过空间杜宾模型的研究表明,低碳能源转型对收入不平等的影响存在空间溢出效应,可降低邻近地区的收入不平等。【结论】应大力发展可再生能源,强化区域间能源转型的常态化交流与合作,充分发挥低碳能源转型对劳动力技能结构的提升作用,从而实现促进低碳能源转型和缩小收入差距协同发展。
[Objective] As a systemic transformation of the economic and social system,the lowcarbon energy transition will inevitably impact social issues such as equity and income.Investigating the impact of city low-carbon energy transition on income inequality can provide valuable empirical insights for coordinating the low-carbon transformation of the economy and society and for narrowing income gaps.[Methods] This study used the panel data from 281prefecture-level cities in China from 2007 to 2020 as the research sample,and established a multidimensional indicator system to calculate city low-carbon energy transition index.Based on the nighttime light data of 2109 districts and counties,the income inequality between different urban income groups was measured.Subsequently,the intrinsic relationship between low-carbon energy transition and income inequality was examined by both theoretical modeling and empirical analysis.[Results](1) The low-carbon energy transition significantly alleviated income inequality,with each standard deviation increase in the transition index reducing income inequality by approximately 6.1%.(2) Mechanism analysis indicated that the low-carbon energy transition affected income inequality through skill-biased technological progress and the upgrading of the labor force's skill structure,with the alleviating effect on income inequality mainly stemming from its role in enhancing the skill structure of the labor force.(3) Heterogeneity analysis revealed regional and urban characteristic heterogeneity in the impact of low-carbon energy transition on income inequality.(4) The research using the spatial Durbin model showed that the impact of low-carbon energy transition on income inequality had spatial spillover effects,which can reduce income inequality in neighboring areas.[Conclusion] Renewable energy should be vigorously developed,and regular exchanges and cooperation in energy transition between regions should be strengthened to fully leverage the transition's role in upgrading the labor force's sk
