Can environmental tax promote green M&A in emerging market firms? Evidence from China's heavy polluters

Based on a sample of heavily polluting firms listed in China, we examine the impact of environmental taxes on the green M&A behavior of these firms. Our findings underscore that environmental taxes have significantly increased the likelihood of heavily polluting firms engaging in green M&A endeavors. This impact is particularly pronounced in areas with high media attention, low financing constraints, and high environmental investment. However, our examination of the economic consequences shows that green M&A does not improve the green innovation performance and ESG performance of firms. The analysis of M&A motivations shows that the majority of heavy polluters' green M&A targets are located in regions with weak environmental regulation, confirming that green M&A under the environmental tax burden is a tool used by firms to engage in pollution transfer. In addition, green M&A under the environmental tax burden is characterized by financial investment, connected M&A, and nonsignificant M&A, confirming that green M&A under the environmental tax burden may be a tool used by companies seeking only the appearance of “greenwashing.” Therefore, green M&A under the environmental tax burden tends to be underpinned by opportunistic motives of pollution transfer and “greenwashing,” rather than substantive green transformation and upgrading. We provide evidence from emerging markets on the impact of environmental taxes on green M&A, which adds to the literature in this area and has policy implications for government regulation of corporate environmental governance practices.
