Do green policies catalyze green investment? Evidence from ESG investing developments in China

This study examines the heterogeneous performance of ESG investing in China before and after 2016, when the “Guidelines for Establishing a Green Financial System” was announced. In the portfolio analysis, high ESG portfolios earn significantly higher abnormal returns compared to low ESG portfolios in the post-2016 context, but this is not the case pre-2016. This outperformance is not closely related to common firm characteristics. Next, the stock analysis also shows that good ESG profiles predict higher future excess returns on average post-2016. The rising performance of good ESG stocks largely depends on equity cost advantage other than profitability improvement.
