Developing both subjective and objective measures of the concept of corporate entrepreneurship would be of interest to the field of entrepreneurship. This study (1) develops an objective measure of one domain of corporate entrepreneurship, product innovation, using archival data, and (2) uses a self-report questionnaire as a subjective measure for the same domain. Both the subjective and objective measures were statistically reliable and no significant differences between the two measures were found. Implications for both academic researchers and practicing managers are noted.
