Abstract： In this study, we use the corporate social responsibility disclosure (CSRD) data of listed companies in China from 2010 to 2014 to explore the relationship between vertical interlock and CSRD in the business group. We find that companies in business group tend to disclose CSR information but vertical interlock will hinder the disclosure of CSR and impact the quality of CSRD. However, the relationship mentioned above can only be observed in the state-owned companies and a higher position of interlocked director in stated-owned business group will lead to a lower desire to disclose CSR. We explain the phenomenon based on the capability of the interlocked director to access resources and the sufficiency of resources in the business group with different ownership.
