7.企業社會責任(Corporate Social Responsibility,CSR)課題日受到實務界和學術界的重視,雖然善盡金業社會責任需投入成本,但獲得的益處通常更多,例加:刊登於世界第1名之財務金融學術期刊(Joumal of Finance)的文章:Lins,Servaes and Tamayo, 2017, Social Capital, Trust, and Firm Performance: The Vahne of Corporate Social Responsibility during the Financial Crisis.茲將此文章之摘要節錄如下: During the 2008-2009 financial cris, firms with high social capital, as measured by corporate social responsibility (CSR) intensity,had stock retums that were four to seven percentage points higher than firms with low social capital. High-CSR firms also experienced higher prottability, growth, and sales per employee relative to low- CSR firms, and they raised more debt. This evidence suggests that the trust between a firm and both its stakeholders and investors, built through investments in social capital, pays off when the overall level of trust in corporations and markets suffers a negative shock. 請您依據上述摘要說明善盡企業社會責任的公司(High-CSRfirms)在金融海嘯艱固時期產生哪五種好 處?(本題10分,每一答案2分)
