This dissertation investigates the following questions. How does the structure of ownership, board governance, and board monitoring influence the corporate entrepreneurship behaviour of privatised firms in Vietnam? Furthermore, does uncertainty regarding the changing business and institutional environment moderate the relationships among corporate governance, ownership structure, and corporate entrepreneurship?In the dissertation, Stewardship Theory, Institutional Theory, Resource Dependence Theory, are integrated with Agency Theory to provide a framework to investigate the relationships between board composition, ownership structure and corporate entrepreneurship in post-privatisation environments. The theoretical arguments are tested using a mixed-method approach, based on a survey of privatised Vietnamese firms and data collected and collated from in-depth interviews of board and top management team members in six selected privatised firms. The study findings indicate that a reliance on any single theoretical lens is ineffective in explaining the phenomenon in the context of privatised firms in transition economies, and that the employment of multiple theories is crucial for providing a complete understanding of context-dependent phenomena, such as corporate governance. Empirically, the results show that the board composition and characteristics have little impact on corporate entrepreneurship and ownership structure almost plays no role in enhancing the entrepreneurial activities of privatised firms. In particular, the study highlights that there are no unique corporate governance practices that can be employed in every context. The practices are effective only in certain conditions and specific environments. The study provides a set of policy and managerial implications for shaping corporate governance in order to foster corporate entrepreneurship in Vietnamese privatised firms.
