This paper proposes a model to analyze firms' CSR behavior in a successive monopolistic market. Given that CSR investment can raise consumers' willingness to pay (WTP), firms choose the degree of CSR investment strategically. In contrast to the results of Brand and Grothe (2015), the results show that the retailer as a leader in CSR investment is better off in the sum of retailer's and manufacturer's equilibrium profits, consumer surplus and social welfare.

本文提出一個分析連續獨占市場的企業社會責任行為模型，基於企業社會責任（CSR）投資能夠提高消費者的願付價格（WTP），廠商策略性選擇其企業社會責任投資的程度。與Brand和Grothe（2015）的結果相反，本文顯示在零售商領先選擇企業社會責任投資的模式下，製造商和零售商的均衡利潤總和、消費者剩餘及社會福利最佳。
