本研究結論為投信業者能在國際金融競爭下,必須重新尋找到經營的立足點,成為台灣投資人長期投資的工具,引導國際資金注入台灣共同基金市場,拓展經濟規模才能維持永續經營。;The financial industry has changed rapidly. Started with 4 Asset Managers established in 1983, there are 38 Asset Managers operating in Taiwan currently. As of the end of December 2016, 725 mutual funds had been launched in Taiwan, of which 69 were index funds, 338 were equity funds. It was estimated that NTD 2.12 trillion of asset had been generated. However, compared with the asset level of NTD 2.28 trillion during the financial crisis in 2008, the overall size of the asset dropped instead. Struggling with its current business model, the Asset Management industry in Taiwan has been losing its momentum in enlarging asset under management (AUM) for years. Nevertheless, even encountering the same challenges with all competitors, the AUM of Yuanta SITE - the largest SITE in managing mutual funds in Taiwan and Cathay SITE - the largest onshore asset manager increased in the same period. Taiwan Asset Management industry is at the stage of maturity and asset managers are now facing fierce competition and external opportunities and threats. This research analyzes the current business models of both Yuanta SITE and Cathay SITE, using the framework of 8-Cross business model. Further this study uses the 8-Cross SWOT framework to explore key factors for success of both Yuanta and Cathay SITE facing the changes of external environment. The conclusions of this study suggests that both Yuanta SITE and Cathay SITE should establish new strategies and tactics and setup operational model systematically. The asset managers may be able to find their business niche, aiming to be the long-term investment instrument for Taiwan investors as well as attracting foreign funds to invest into Taiwan mutual funds to expanding Taiwan mutual fund business.
