Due to the dramatic evolution of computer and information technologies and severe competition in the internet service industry in recent years, more internet service providers (ISPs) have consistently employed strategic alliances, such as with internet content providers, to strengthen their abilities to compete. To explore the current developments in the ISP industry, this study utilized two methods, a questionnaire survey and in-depth interviews to discover: (1) the current employment of strategic alliances in the ISP industry; (2) ISPs’ performances after joining strategic alliances; and (3) factors influencing successful strategic alliances for ISPs. The study found that 92 percent of the ISPs in Taiwan engage in strategic alliances with other enterprises. In addition, the types of alliances in which most ISPs engage in Taiwan are marketing alliances, service alliances, and information alliances. Finally, more than 90 percent of ISPs which engage in strategic alliances are reported to be successful in terms of sales amount or revenue. The important factors influencing successful strategic alliances are: benefit sharing, mutual trust, strategy-based consideration, and ease of communication.
