Using data of Chinese listed firms between 2008 and 2013，we investigate the effect of controlling shareholders and international investors on CSR report of Chinese listed enterprises.We find empirically that SOEs are more likely to provide CSR reports，but most of which are mandatory disclosure in nature.As the quality of private firms reporting is high，local government controlled SOEs tend to provide CSR reports with low quality.International investors have a positive effect on CSR disclosure，but only in central government controlled SOEs and private enterprises.
