A Study of How Tax Treaty and Tax Reform Effect Equity FPI in China

在國際金融蓬勃發展的現況下，國際間的租稅協定與租稅政策如何吸引投資者進行外國證券投資，為各國促進國際金融與經濟的發展的重要議題。本研究探討的問題為國際間的租稅協定與個別國家的租稅改革是否影響投資人在進行外國證券投資的投資決策。 本研究以中國為例，探討於2008年中國實施新企業所得稅法後，與中國簽有租稅協定國之境外投資人，是否因其適用的股利所得稅率較非租稅協定國低，而有較大誘因與動機增加其對中國的外國證券投資金額。而實證結果顯示，於中國2008年的租稅改革後，與中國簽有租稅協定國的境外投資人明顯增加其對中國的外國證券投資額。此結果證明，租稅協定與租稅政策對外國證券投資者的投資之決策有其影響力。Since Global Financial has grown rapidly, how countries develop their financial markets and economics by abstract foreign portfolio investment (FPI) through international tax treaty and tax policy has become an important issue. And this study examines the relationship between tax treaty and tax reform to FPI, in order to see how taxation effects foreign investors’ investment decisions. This study derives the hypothesis that Enterprise Income Tax Law of the People’s Republic of China of 2008 should lead to a portfolio reallocation by foreign investors toward equities in tax-favored countries. An analysis that compares foreign equity holdings in treaty and un-treaty countries with China finds a substantial portfolio reallocation toward the former. The empirical results of the study indicates that after the tax reform of 2008 in china, treaty countries have more incentive than un-treaty countries to increase their FPI toward equities due to their lower dividends tax rates. And this result suggests that tax treaty and tax reform have an impact on FPI investors’ decisions
