Financial decisions play an important role in business operations. Previous researches have proven that capital acquisitions as well as capital applications have close relationships with the financial performance of businesses. Using the panel data of manufacturing firms listed in the Taiwan Stock Exchange, this paper intends to explore the relationships between methods of financing and business performance in Taiwanese enterprises. Distinctions are also made between technology and conventional firms. The results show that firm’s capital acquired by the ways of equity, retain earning and depreciation, and capital applied to the current asset, fixed asset and long-term investment can effectively increase the performance of businesses. For technology firms, choosing low debt ratio and maintaining sufficient cash are considered to be better financial strategies. While for conventional firms, due to the agency problems, having a large debt ratio might not be a bad strategy. In all, industries with distinctive future development or growth opportunities should have different financial strategies.
