Supply Chain Concentration, Financing Constraints, and Carbon Performance

Companies have been implementing various strategies, such as supply chain reconfiguration and process optimization, striving to find an efficient and effective solution for enhancing carbon performance over the last decade. Although various factors that may influence supply chain carbon performance have been investigated, the impact of supply chain concentration remains unclear due to insufficient research and inconsistencies in conclusions from the existing research. It is essential for enterprises to understand whether and to what extent supply chain concentration is an effective measure for improving carbon performance. Equally important is understanding the situations in which supply chain concentration works more effectively. In this research, we will construct fixed effects models using data from Chinese A-share listed companies from 2012 to 2021 to investigate the effects and mechanisms of supply chain concentration on corporate carbon performance. Our results suggest that supply chain concentration has a significant positive effect on carbon performance, with financing constraints playing a partial mediating role in this relationship. In addition, we have found that managerial myopia has a negative moderating effect on the positive relationship between supply chain concentration and carbon performance, whereas unexpected public events positively moderate this relationship. Further research indicates that the effect of supply chain concentration on carbon performance is stronger for state-owned enterprises and low-growth enterprises in China.
