This paper measures the “greenium” in China’s stock markets with data during 2011-2020. We find that the green stocks outperform the brown ones in China and public climate concern brings the greenium. Based on the phenomenon, with panel regression, we furtherly figure out that the firms’ stock returns are positively correlated with their ESG rating, and public climate concern strengthens the relationship, which suggests that China’s stock investors behavioral bias contributes to greenium.
