Environmental regulation and outward foreign direct investment: evidence from Chinese firms’ overseas mergers and acquisitions

While the literature shows that stricter environmental regulations deter exports and inward foreign direct investment (FDI), few studies examine the impacts on outward FDI, especially for developing countries. In this paper, we analyse this issue in the context of China, which is the largest developing country in terms of FDI. We collect the transaction-level data of all the overseas mergers and acquisitions (M&As) by Chinese firms from 2000 to 2019. For the identification of the causal effect, we exploit the implementation of the Environmental Protection Law in 2015 as a quasi-natural experiment and carry out the difference-in-difference-in-differences analysis (DDD). The results show significant impacts of stricter environmental regulations on outward FDI. When the provincial emission reduction target increases by 10% points, the number of overseas M&A transactions in the high-polluting industries has increased by 32 every year since 2015. Moreover, the investments are more likely towards countries with better environmental protection. This suggests that firms aim at gaining cleaner technologies via M&As rather than transferring pollution abroad.
