本文研究了竞争市场中企业在碳交易价格和消费者碳意识双重压力下的碳减排与定价策略。我们建立了一个双寡头博弈,并研究了问题参数如何影响均衡结果。我们发现,碳价格和消费者意识水平对企业的减排努力具有叠加效应。然而,这两个因素对公司的价格和利润有不同的影响。特别是,当碳排放总量适中时,企业的碳价格会随着消费者的碳意识水平先下降后上升,而企业的利润则会随着碳价格的上升先下降后上升。从消费者和企业的角度来看,中央计划者的减排策略是先提高碳价格,然后提高消费者的碳意识。这种战略为企业投资碳减排活动提供了激励,而不会对产品价格和企业利润造成剧烈变化。最后,我们将基本模型推广到考虑两个以上的公司。研究发现,对于中央计划者来说,提高碳价可能是一种比提高消费者意识更好的政策选择,因为中央计划者的目标是在不同竞争水平的行业中减少碳排放。
This paper studies firms' carbon emissions abatement and pricing strategies in a competitive market when facing the pressure from both emissions trading price and consumer carbon awareness. We develop a duopoly game and investigate how problem parameters affect the equilibrium outcome. We find that carbon price and consumer awareness level have an additive effect on a firm's emissions abatement effort. However, these two factors have different implications for the firms' prices and profits. In particular, the firms' prices first decrease and then increase with consumer awareness level, while the firms' profits first decrease and then increase with carbon price when there is a moderate emissions cap. From both the consumers' and the firms' standpoints, an appropriate emissions abatement strategy for the central planner is to first push up the carbon price and then promote consumer carbon awareness. Such a strategy provides incentives for firms to invest in carbon abatement activities, without causing drastic changes to product prices and firm profits. Finally, we generalize the base model to consider more than two firms. It has been found that raising carbon price may be a better policy choice than promoting consumer awareness for the central planner who aims at reducing carbon emissions in various industries with different competition levels.
