This study examines the impact of regional carbon peaking pressure (CPP) on corporate R&amp;D investment, using panel data from Chinese A-share listed manufacturing firms between 2015 and 2020. By employing a two-stage least squares approach, we find that higher CPP significantly boosts R&amp;D investment, particularly in R&amp;D-intensive firms, state-owned enterprises, and firms with lower tax payments. In contrast, firms with lower R&amp;D investment ratios, private firms, and major tax contributors exhibit a weaker response to CPP. In addition, while CPP increases R&amp;D investment, it also introduces trade-offs, such as reduced management expenses and temporary declines in productivity.</div></div>","PeriodicalId":11468,"journal":{"name":"Economics Letters","volume":"251 ","pages":"Article 112328"},"PeriodicalIF":2.1,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By breaking down absolute economic mobility into these three areas, we explain how each component contributed to real per-capita expenditure changes due to tariff reductions.

Our analysis also considers if non-coresident father-son pairs behaved differently relative to coresident pairs. Further, we explore if the economically vulnerable segments were able to participate in the overall patterns experienced by the economy. We find that tariff reductions fostered absolute economic mobility of real per-capita expenditures by promoting regional growth, reducing inequality, and enhancing relative economic mobility, particularly benefiting the individuals and households in the lowest quartile.
