Balancing profit and planet: The effect of corporate tax rates on environmental quality and innovation in Asian Countries

In contemporary literature, extensive research has focused on the influence of environmental taxation on the environmental performance of industrial sectors. However, it is still uncommon in the existing literature how corporate statutory tax rate (CTR) affects environmental performance. Therefore, this study aims to empirically investigate the relationship between CTR and environmental quality (ENQ) as well as environmental innovation (EIN). To conduct this analysis, we utilized 19 years of financial data spanning from 2001 to 2019 across all 48 Asian economies. Our research employed both panel quantile regression (PQR) and system GMM models for the regression analysis. The empirical findings reveal that the corporate statutory tax rate has a positive impact on CO2 emissions, leading to deterioration of the environmental quality, while simultaneously exerting a negative influence on environmental innovation, inhibiting green innovation. These effects of the CTR on ENQ and EIN remained consistent even when controlling for factors such as economic growth, foreign capital, financial development, and environmental taxation. These findings have significant policy implications, suggesting the need for a reevaluation of current tax policies and the introduction of tax rebates for companies striving to enhance their environmental sustainability. This study contributes to the literature by shedding light on the adverse consequences of high taxation on the environmental performance of businesses.
