Technology Strategy becomes gradually important in these years, when the technology divides into various segments so that the firms are enforced to collaborate with external network linkage. This is a survey research to study the influential factors of the company performance in computer industry in Taiwan. The two independent factors are technology strategy and external network. By using the random sampling method, the questionnaire was mailed to members of Taiwan Electrical and Electronic Manufactures Association. We collected one-hundred-and-forty-four valid responds that were used for the statistic analysis. The empirical results show that the external network does not directly affect the company's performance, but through the technology strategy. In addition, because the model fit computed by the LISREL is not satisfactory, several adjusted models are added for the result comparison.
