This study selects A-share listed companies in China from 2009 to 2023 as the research sample to investigate the impact of supply chain concentration on corporate ESG rating divergence. The study finds that supply chain concentration has a significantly positive correlation with corporate ESG rating divergence. Supply chain concentration further influences ESG rating divergence by affecting information transparency, verifying the mediating role of information transparency. Behavior related to analysts' earnings forecasts plays a negative moderating role between supply chain concentration and ESG rating divergence. Heterogeneity tests reveal that the positive impact of supply chain concentration on ESG rating divergence is more pronounced in state-owned enterprises.
