To Invest in Mainland China becomes Taiwan corporations¡¦ high priority by virtue of China¡¦s vast internal consumer market, the trade liberalization after joining WTO, low labor cost, and easy communication in Chinese language. However, the special relationship between Taiwan and China induces Taiwan corporations¡¦ investment risks due to political uncertainties. The establishment of information and communication network between headquarters in Taiwan and their mainland subsidiaries enables the governance and coordination between two sides. However, bearing these special relations, it is a nontrivial question to ask any unique information infrastructure and system that Taiwan corporations adopt which may be consistent with or different from prior literatures in multi-national corporations. This thesis develops a conceptual framework to identify the relationship between the factors and IT configurations, and then proposes propositions to explain findings from three Taiwan companies, which have subsidiaries in China. This study asserts that the political uncertainties that influence the IT configuration of Taiwan companies with subsidiaries in China are common with multinational firms whose headquarter and subsidiaries have normal relationship. The major contribution of this study is to explore the factors that affect Taiwan companies¡¦ IT governing practice toward their China subsidiaries.
