扩展Hotelling模型下双寡头制造商的低碳策略选择

在一个扩展的Hotelling模型中,研究了双寡头制造商在考虑了消费者低碳偏好情况下的低碳策略选择问题。消费者对低碳效用的偏好程度直接影响到制造商的收益,从而影响到两个制造商在竞争关系下的低碳策略选择。分别求得了在四种情形下两个制造商各自的最优价格及其收益,通过比较分析,得到两个制造商进行低碳策略选择的均衡状态。通过数值仿真,比较了两个制造商在不同选址条件下的盈利情况。研究结果表明:当消费者低碳意识薄弱时,两个制造商均不采用低碳策略;当消费者低碳意识较强时,两个制造商均采用低碳策略。

Research on Low Carbon Strategies of Duopoly Manufacturers Based on Extended Hotelling Model

In an extended Hotelling model, duopoly manufacturers who considered consumers' low carbon preference will decide to whether adopt low carbon strategy or not, The degree of consumers' low carbon preference influences directly the profits of the two manufacturers, and further influences the manufacturers' low carbon strategies choice in a competitive relationship, The optimal prices and profits of the manufacturers in four kinds of situations are yielded. Comparing respectively with the two manufacturers' optimal profits in four kinds of situations and get low carbon strategy equilibrium of the two manufacturers Through numerical simulation, compare the profitability of the two manufacturers in different location conditions, The results show that neither of the two manufacturers adopt low-carbon strategy ff low carbon preference of consumers is weak and both of the two manufacturers adopt low-carbon strategy ff low carbon preference of consumers is strong.
