Multinational companies face increasing competition due to globalization. As per the World Investment Report 2010, Taiwan received foreign direct investment of $ 5,868,000,000 during 2009. The United Nations Conference on Trade and Development Committee included 30 Taiwanese corporations in the global rankings. Enterprises conducting international trade inevitably face many uncertainties and incur significant expenses. This is accompanied by an improved financial performance along with an increase in the relative risks. The existing literature, which covers nearly three decades of research, indicates that empirical results vary across internationalization and financial performance. This study initially examines the financial performance of various listed companies (both multinational and non-multinational) in Taiwan in 2009. In addition, this paper explores the internationalization of Taiwan’s listed companies during 2001-2009. The results of the study indicate that variations in financial performance are independent of a company’s multinational/non–multinational status.
