两周期双寡头竞争环境中再制造影响

针对两周期双寡头竞争市场,分别构建单个企业实施再制造和两个企业实施再制造的产量决策模型,探讨再制造对双寡头竞争市场的产品供应、产品价格、企业利润、消费者福利以及环境污染的影响.研究表明:1)当且仅当再制造补贴与再制造成本节约之和满足一定条件时,双寡头才会进入再制造市场.2)再制造可增加企业利润、提高消费者剩余,并在一定...

Effect of remanufacturing on duopoly competition in two-period

This study focuses on the effect of remanufacturing on duopoly competition in a two-period planning horizon. To conduct a convincing analysis, we develop two models to derive the conditions under which one manufacturer implements remanufacturing and two manufacturers implement remanufacturing in a duopoly situation. Furthermore, we analyze the influence of remanufacturing on quantity, price, corporate profits, consumer surplus, and the environmental pollution. The results show that: 1) Only when the sum of the remanufacturing subsidy and the cost savings of remanufactured products meet certain conditions, the duopoly will implement remanufacturing; 2) Remanufacturing can increase the remanufacturer''s profit, total consumer surplus in two-period, and leads to a better outcome for the environment if the unit pollution of remanufacturing is low enough. In addition, if the value of the remanufacturing subsidy is high and the cost savings of remanufactured products is large, remanufacturing can increase the supply of new products in the first period; 3) If only one firm adopts remanufacturing, remanufacturing could bring competitive advantage for remanufacturer in terms of market share and profit, and if the sum of the remanufacturing subsidy and the cost savings of remanufactured products is large enough, the remanufacturer will monopolize the first period market.
