Ownership structure, corporate governance and productive efficiency in China

This paper investigates whether and to what extent ownership structure and corporate governance affect productive efficiency in a sample of 744 publicly listed manufacturing firms in China between 1999 and 2006. The paper finds that firm efficiency, as estimated using stochastic frontier analysis and data envelopment analysis, is negatively related to state ownership while positively related to public and employee share ownership. In addition, the relationship between ownership concentration and firm efficiency is U-shaped, indicating that the largest shareholder may engage in tunneling activities. As the identity of the largest shareholder changes from government, government-controlled legal entity to other types of legal entity, firm efficiency significantly improves. These results provide strong evidence that political interferences have reduced firm efficiency. Moreover, firms with more independent board are more efficient, supporting the argument that board of directors can be an effective internal governance mechanism. Furthermore, provincial market development, a proxy for the strength of external governance mechanism, is positively related to firm efficiency. Overall, the findings illustrate that restructuring state-owned enterprises via improvements in corporate governance has enhanced firm efficiency, but partial privatization without transfer of ownership and control from the state to the public remains a major source of inefficiency in corporate China.
