    摘要:

    提出由两个再制造商组成的环保质量和价格竞争的双寡头博弈模型.在一个再制造市场中,同时考虑消费者环保意识以及包括污染税和回收补贴在内的政府财政政策的情况下,探讨绿色网络效应对生产决策的影响,以期使企业的利润最大化.数值实验表明:高质量(低质量)产品的绿色网络效应系数越高(低),可能会反常地减少(增加)两种产品的环保质量和价格,但会促进(削弱)高质量(低质量)产品的销售和利润,而产品产异性不受影响;此外,相比较没有外部网络性的情况,在绿色网络效应的影响下,回收补贴的增加使得高质量 (低质量)产品的需求和利润都得到了一定改善(削弱).结果表明,在最优化条件下,监管者总是可以使企业利润和消费者剩余构成的“经济盈余”最大化,并使排放总量最小化.

    Abstract:

    This paper presents a model of duopolistic competition in terms of both environmental quality and price, which investigates the impact of the green network effect(GNE) considering consumer environmental awareness(CEA) and government financial policies combining of pollution tax and recovery subsidy, with the objective of profit maximization for the remanufacturing firms. Numerical results reveal that a higher(resp. lower) GNE coefficient of a high-quality product may abnormally reduce(resp. increase) both the environmental quality and price of products but raise(resp. shrink) the consumption and profit of the high-quality(resp. low-quality) product, although product differentiation is not impacted by it. Moreover, the increase of recovery subsidy allows for better(resp. worse) market demand and profit for the high-quality(resp. low-quality) product in the presence of positive GNE compared to that in the absence of GNE. However, under best optimum, the regulator can always maximize the “economic surplus” consisting of firm's profits and consumer's surplus and minimize the amount of emissions.
