本研究利用具有生產外部性的獨占市場模型，探討社會企業責任對社會福利分配的影響。結果發現：1、當廠商關心消費者導向的企業社會責任下，消費者剩餘增加，廠商總利潤減少，污染總量增加；對於社會福利的影響將呈現先上升後下降的非線性關係。2、當廠商關心勞工導向的企業社會責任下，工會效用增加，廠商利潤減少；並不會影響社會的總產量、總污染量以及總社會福利。3、當廠商關心環境導向的企業社會責任，工會效用下降，廠商利潤減少，社會總福利下降，社會將陷入三輸。

This paper explores the impact of Corporate Social Responsibility on the distribution of social welfare by using the monopoly model with production externality. It comes to three kinds of results. First, if the firm cares about the consumer- oriented CSR, then the consumer surplus increase, the firm's total profit decrease, and the total quantity of pollution increase. The impact on CSR will be an inverted U- shaped relationship. Second, if the firm cares about the labor-oriented CSR, then the effectiveness of union increase, the firm's profit decrease, but it will not have impact on the total social output, or the total quantity of pollution, or the total social welfare. And the last is, if the firm cares about the environmental- oriented CSR, then the effectiveness of union decrease, the firm's profit decrease, and the total social welfare decrease. The whole society will be a triple- lose situation.
