Manuscript Type Empirical Research Question/Issue This study analyses whether institutional investment in China is affected by the voluntary corporate social performance (CSP) of firms, after controlling for ownership structure, corporate governance, compensation, and other firm characteristics. Research Findings/Insights Firms with superior voluntary CSP attract more institutional investment, which remains robust after controlling for the reverse causality problem. Mutual funds are the main driver of the institutional investment pattern in China and they invest more in firms that achieve better voluntary CSP with respect to employment equality and customer care. Insurance companies and social security funds invest more in firms that take care of their customers. Qualified foreign institutional investors (QFIIs) are the only type of institutional investors tilting their investment in favor of firms doing well at saving energy. Theoretical/Academic Implications Our empirical evidence suggests that different types of institutional investors show preferences toward different aspects of investee firms’ voluntary CSP. We innovatively separate firms’ voluntary CSP into expected components that can be explained by firm characteristics and unexpected components (surprises) that cannot be explained by firm characteristics. Although institutional investors, in general, and mutual funds and QFIIs, in particular, own more shares in firms with more voluntary CSP surprises, only mutual funds trade on them in the subsequent year. Practitioner/Policy Implications Foreign institutional investors invest more in firms with better voluntary CSP, especially with respect to energy‐saving and environmental issues, but they do not show a significant preference toward firms with better corporate governance in China. Our paper offers implications for policy makers in transitory and emerging economies with regard to encouraging foreign institutional investors’ equity investment.
