This paper constructs an oligopoly model incorporating corporate social responsibility (β) and consumer sensitivity (e). We analyze the impacts of β and e on overcapacity, profits, consumer surplus, and social welfare under Cournot competition, Stackelberg competition, and Price Leadership competition. The results show that different competition modes produce different degrees of overcapacity. β has complex impacts on profits and affects the comparisons of social welfare. e positively influences equilibrium results. Enterprises have the motivation to voluntarily undertake corporate social responsibility after introducing consumer sensitivity. However, their voluntary commitment level is always lower than that formulated by the government.

企业社会责任、消费者敏感性和产能过剩

本文构建了一个结合了企业社会责任（β）和消费者敏感性（e）的寡头垄断模型。我们分析了在古诺竞争、斯塔克伯格竞争和价格领先竞争下，β和e对产能过剩、利润、消费者剩余和社会福利的影响。结果表明，不同的竞争模式会产生不同程度的产能过剩。β对利润有复杂的影响，影响社会福利的比较。e对平衡结果产生积极影响。引入消费者敏感性后，企业有主动承担企业社会责任的动力。然而，他们的自愿承诺水平始终低于政府制定的水平。
