This paper is to explore the status of application for academic outcomes of strategic management into corporate management practices. We attempt to reflect the theme of this research based on the strategic thinking and practices of Taiwanese businessmen entering the mainland market. At the beginning of the opening of the mainland market, Taiwanese businessmen didn't know much about the information on the mainland market, or even knew nothing. How do managers develop strategies to enter the mainland market in their practical operations? How to grasp the market and competitors' trends? When they have been in the mainland market, how to gain a foothold in the highly competitive market? Furthermore, in the daily operation activities of managers, how much time is spent in formulating strategies? Finally, this study explores the above issues to better understanding of the role played by the academic theory of strategic management in practical operations when Taiwanese businessmen enter the Chinese mainland market.
