碳排放权交易试点政策对城市碳公平的影响OA

Since the implementation of the carbon emissions trading pilot policy,its effects on emission reduction and technological in‐novation have received widespread attention;however,few studies have discussed the policy's impact from the perspective of carbon eq‐uity.Exploring how to achieve regional and intergenerational carbon equity is of great practical significance for attaining sustainable de‐velopment and the"dual carbon"goals.To this end,this study calculated the carbon equity indices of 284 prefecture-level cities and above in China from 2004 to 2022 based on the Theil Index and used a multi-period difference-in-differences(DID)model to test the impact of the carbon emissions trading pilot policy on regional carbon equity and intergenerational carbon equity in pilot cities.The re‐sults showed that:① During the study period,China's overall carbon equity indices showed a downward trend.At the provincial level,provinces with higher carbon equity indices shifted continuously from east to west and from coastal to inland areas,while the gap in car‐bon equity indices at the prefecture level was gradually narrowing.② Compared to the control group,carbon equity indices of the treat‐ment group decreased significantly by an average of 0.019,indicating that the carbon emissions trading pilot policy was conducive to promoting carbon equity in pilot cities.③ Mechanism analysis revealed that the cost effects,innovation effects,and expectation effects of the pilot policy promoted carbon equity in pilot cities by reducing total energy consumption,increasing the number of low-carbon pat‐ent applications and grants,and raising the frequency of green and low-carbon terminology in government documents,respectively.④ Further analysis,which involved calculating the intergenerational carbon equity indices for each city,demonstrated that the pilot car‐bon emissions trading policy significantly promoted intergenerational equity of carbon emissions in pilot cities.Based on these findings,this study proposes that China should draw on the pilot experience to improve the national carbon market and fully leverage the cost,in‐novation,and expectation effects of the policy.Specifically,it is necessary to continuously strengthen market supervision,increase in‐vestment in innovation and subsidies,reinforce patent protection measures,and enhance green guidance to raise environmental aware‐ness among the public and enterprises.Furthermore,adherence to the concept of sustainable development is essential;the rights and in‐terests of future generations must be safeguarded while ensuring contemporary economic development to achieve intergenerational car‐bon equity,fulfill the carbon neutrality goal,and construct a new pattern of urban low-carbon development.
