Corporate governance, CG, is mainly occupied with the disciplining aspects of governance system on listed corporations. Corporate entrepreneurship, CE, has been occupied with the enabling aspects of developmental activities within listed corporations and SMEs. The ambition of this paper is to present an integrated theory of CG and CE, claiming CG to have influence on CE. In order to reduce the complexity in this endeavour, the paper focuses on two CG mechanisms, the classical Chandlarian mechanisms of strategy and structure. The empirical focus abandons the commonly investigated listed corporations and focuses instead on the non-profit association and the privately held firm, active within the riding industry. The analysis indicates that the privately held firm and the non-profit association differ in characteristics of the CG mechanisms. However, these differences do not indicate significant different influence on CE.
