Since the mid 1990s the State-Owned Assets Supervision and Administration Commission (SASAC) has emerged as a key institution governing firm ownership in China, but its impact on firm performance is understudied. Through an analysis of Chinese firms listed on the Shanghai and Shenzhen stock exchanges from 1994-2003, we examine how the changing ownership patterns following the rise of SASAC influenced firm performance. We have three findings. First, contrary to the popular view that state ownership in China's listed firms has declined, we find that the state shares have been moved from the original state offices to the SASAC in the format of ‘state institutional shares’. Second, compared with the old state shares, the SASAC institutions affect firm performance more positively. Third, after controlling for state and SASAC ownership, ownership concentration is a strong positive factor in firm performance. Our findings fit squarely within a long tradition of agency theorists who argue that ownership concentration helps solve the free-rider problem and thus has positive effects on firm performance. However, we focus on the ways in which ownership concentration allows firm owners to monitor and stabilize firm behaviour, which has more important implications for emerging economies such as China's domestic capital markets.

Drawing on institutional theory, this study empirically examines the relationship between a firm's levels of ownership concentration and product innovation and the mediating effect of learning orientation, using a sample of 351 Chinese firms. Does ownership concentration hinder or promote firm innovation? Perspectives on this relationship are divergent. This study examines the link between ownership concentration and product innovation and further examines whether and how ownership influences firm innovation through organizational learning. The results suggest that ownership concentration has an inverse U-shaped relationship to product innovation and to learning orientation. In addition, learning orientation mediates the curvilinear relationship between ownership concentration and product innovation. We discuss the study's contributions, managerial implications and directions for future research.

By examining the level of ownership concentration across firms, we determine how principal–principal conflict, defined as the incongruence of ownership goals among shareholder groups in a corporation, impacts agency costs of Chinese boards of directors. Based on data from Chinese companies listed on the Shanghai and Shenzhen stock exchanges during 1999-2003, we found that ownership concentration had a U-shaped relationship with board compensation, board size and the presence of independent directors. These results provide corroborating evidence that principal-principal conflict can lead to high agency costs.
