Income inequality affects not only social well-being, health, and carbon emissions but also the strategy for green development in China. Based on the panel data of 205 cities in China from 2010 to 2020, a panel model with partial linear functional coefficient is used to analyze and test the relationship between income inequality, carbon emissions, and green development efficiency under different regional economic development levels. The empirical results show that the impact of income inequality on carbon emissions and green development efficiency is significant. The worsening of income inequality could aggravate carbon emissions, but the effect of income inequality on carbon emissions shows an increase-decrease-flattening with the continuous improvement of regional economic development. In terms of affecting the green development efficiency, the effect of income inequality on the efficiency of green development presents an inverted U shape. However, the number of cities where income inequality has an inhibitory effect on carbon emissions and green development efficiency has increased over time, and the impact of income inequality in a few cities on green development efficiency is not significant. These findings provide new insights into the understanding of shared prosperity and the strategy of carbon peaking and carbon neutralization in China.
收入不平等不仅影响社会福祉、健康和碳排放，也影响中国的绿色发展战略。本文利用 2010-2020 年中国 205 个城市的面板数据，采用具有部分线性函数系数的面板模型，分析和检验了不同区域经济发展水平下收入不平等、碳排放和绿色发展效率之间的关系。实证结果表明，收入不平等对碳排放和绿色发展效率的影响显著。收入不平等的加剧会加剧碳排放，但随着区域经济发展水平的不断提高，收入不平等对碳排放的影响呈增加-减少-平坦的趋势。就影响绿色发展效率而言，收入不平等对绿色发展效率的影响呈倒 U 型。然而，随着时间的推移，收入不平等对碳排放和绿色发展效率具有抑制作用的城市数量有所增加，而且在一些城市，收入不平等对绿色发展效率的影响并不显著。这些发现为理解中国的共同繁荣和碳峰值及碳中和战略提供了新的视角。
