Investors in the stock market can influence corporate social policy which decidedby the management through their investment decision. The objective of this research is to examine the relationship between perfectionism and high-quality conscious of decision-making style, expressive decision frame, the conscious of ethic and the preference of CSR investment decision by investor. The result of this study, based on both paper-questionnaire and web-questionnaire survey of individual investors in Taiwan, suggests that there is positively and significantly relationship between perfectionism and high-quality conscious of decision-making style and the preference of CSR investment decision. In addition, there is also positively and significantly relationship between expressive decision frame and the preference of CSR investment decision. However, the hypothesis of positive relationship between the conscious ofethic and the preference of CSR investment decision by investor is unsupported. At last, we discuss the implications in both theory and identify some practical implications of marketing strategies related to SRI funds. Besides, we also provide some tentative indications of future research.
