Carbon Emission Trading System and Corporate Tax Avoidance
研究发现企业参与碳排放交易体系后，避税行为受到抑制，原因在于企业社会责任增强和监管威慑加强，且在经济发达地区、税收执法强和数字化转型的企业中效果更明显。
ABSTRACT Research Question/Issue The existence of tax spillover effects from environmental policies has been a subject of ongoing debate. While companies may face cost pressures that drive them to engage in increased tax avoidance, they may also suppress tax avoidance due to considering social responsibility. This study explores the impact of the carbon emission trading system (ETS) on corporate tax avoidance behavior. Research Findings/Insights We find that tax avoidance activities are suppressed after companies participate in ETS. ETS curbs corporate tax avoidance by enhancing corporate social responsibility and strengthening regulatory deterrence. This effect is more pronounced in firms located in more economically developed regions, those with stronger tax enforcement, and companies undergoing digital transformation. Theoretical/Academic Implications This study enriches research on the economic consequences of ETS and the factors influencing corporate tax avoidance, expanding the relationship between tax policies and environmental governance. Practitioner/Policy Implications This study provides government implications in further improving ETS policies to enhance positive spillover effects on taxation and to refine corporate carbon disclosure systems. It also provides guidance for companies to promote tax sustainability by actively participating in ETS and leveraging digital transformation strategies. JEL Classification G10, G23, G30
