ABSTRACTManuscript Type: EmpiricalResearch Question/Issue: We investigate how ownership structure, board characteristics, and regional differences in law enforcement and stock market development affect the conflict of interest between majority and minority investors in Chinese listed firms. For this purpose, we study related‐party transactions as well as labor redundancy, and classify firms as either state‐ or private‐controlled.Research Findings/Insights: We find that related‐party transactions grow more extensive as the wedge between the controlling shareholder's control rights and cash flow rights increases. Related‐party transactions also rise with voting rights held by the government in state‐controlled firms. Next, the state as controlling shareholder exacerbates labor redundancy. The control rights of the second to tenth largest investors can offset expropriation. Regarding board characteristics, we find that a larger fraction of directors affiliated with the dominant owner enlarges related‐party transactions, while large boards also increase labor redundancy in state‐controlled firms. We find only weak evidence that higher‐quality institutions help to restrain expropriation of minority investors.Theoretical/Academic Implications: In Chinese listed firms, a major conflict of interest arises between majority and minority investors. Also, the state may exercise its control rights to achieve imperative social and political objectives, to the detriment of external investors. Yet, as the stock market valuation and financial performance of state‐controlled firms rise with the fraction of shares held by the state, future research should better delineate the conditions under which state ownership is either detrimental or beneficial to firms. Next, the results indicate that governance mechanisms suggested by conventional agency theory are deficient in Chinese listed firms. Future research could therefore establish more clearly when internal and external governance mechanisms are likely to work, thereby also taking into account the identity of the controlling shareholder.Practitioner/Policy Implications: Investors should be aware that expropriation in Chinese listed firms has specific implications when the state is the controlling owner. Also, at this stage of development, independent directors and external governance mechanisms can hardly protect the best interests of minority investors. Rather, expropriation is counterbalanced when voting rights are concentrated in the hands of other large block holders. Policy makers should work on ownership restructuring, board independence, and institutional quality to better protect minority rights in Chinese listed firms.
