摘要:针对双寡头竞争市场,引入竞争强度因子,研究产品存在竞争且零售商重叠的供应链竞争决策问题,分析市场因素对分散供应链决策的影响及竞争强度对寡头企业决策模式选择的影响。结果表明:寡头竞争供应链最优决策受自身供应链的纵向影响和对手供应链的横向影响;相比成本劣势的寡头供应链,占成本优势的供应链会以更低的价格、更优的服务质量抢占市场;仅当竞争强度在一定的阈值内,寡头企业适宜采用联盟决策模式,否则选择独立决策模式。

Abstract:In view of duopoly competition market, decisions of two supply chains having the same retailer are studied under competition of product substitutability. Moreover, sensitivity of some factors and impact of competition intensity on enterprises decision model selection are analyzed. Results show that the optimal decisions of supply chain are effected by their upstream decisions and their opponents decisions. Compared to opponent, the supply chain with cost advantage will adopt a lower price, higher quality service to seize markets. Only if the intensity of competition is within a certain threshold, oligopolistic firms adopt appropriate alliance decisionmaking model, otherwise select the independent decisionmaking model.

Key words:duopoly competition; product substitutability; competition intensity; pricing decision; alliance cooperation

引言

随着市场买卖格局的转变和消费者日益增长的产品个性化追求使市场竞争不断升级,即使是在寡头垄断的行业中,也出现了激烈的竞争,例如可口可乐与百事可乐之间的竞争从1990年至今从未消停过,在其竞争过程中双方多次调整价格及市场推广策略。

由此,部分学者开始研究相关的供应链寡头竞争问题。钟德强等针对异质产品的寡头竞争市场,研究了两家技术创新企业之间的专利技术许可策略问题[1]。而杨建君和聂箐则从技术创新成本和收益的角度出发,分析双寡头竞争企业技术创新的策略选择问题[2]。羡银平等研究碳排量控制对双寡头竞争企业的生产决策的影响[3]。李丽萍等探讨了同质产品双寡头竞争的动态定价问题[4]。胡荣和陈圻利用动力系统理论研究了有限理性双寡头产量竞争的均衡存在和稳定性问题[5]。……
