中文摘要：

构建了制造商主导和销售商主导的两类供应链主导模式，物流外包和物流自营的两类物流模式．研究了制造商主导且物流外包、制造商主导且物流自营、销售商主导且物流外包、销售商主导且物流自营四种组合下的企业决策及供应链稳定性．研究发现：（1）制造商和销售商的物流策略与T/T的大小有关，无论谁为主导企业，若1〈T/T〈√2，则制造商和销售商均选择物流自营，供应链具有稳定性；若T/T〉2，则制造商和销售商均选择物流外包，供应链具有稳定性；若√2〈T/T〈2，则制造商和销售商的物流策略选择不一致，制造商主导（销售商主导）下制造商的最优物流策略是物流外包（物流自营），销售商的最优物流策略却是物流自营（物流外包）．（2）针对四种组合方式，1〈T/T〈√12／5时，制造商主导且物流自营（销售商主导且物流自营）优于制造商主导且物流外包（销售商主导且物流外包）；T/T〉√12／5时，制造商主导且物流外包（销售商主导且物流外包）优于制造商主导且物流自营（销售商主导且物流自营）．

英文摘要：

Two types of supply chain dominant mode--manufacturer dominant and retailer dominant--were constructed, and two types of logistics mode--logistics outsourcing and self-logistics--were given. Enterprise decision making and supply chain stability are studied under four combinations： manufacturer dominant and logistics outsourcing, manufacturer dominant and selfdogistics, retailer dominant and logistics outsourcing, and retailer dominant and self-logistics. It is found that ： （ 1 ） The manufacturer＇ s and the retailer＇ s logistics strategies are related to the size of T/T：if 1〈T/T〈√2 then the manufacturer＇ s and retailer＇ s logistics strategies are both self-logistics, supply chain is stable; if T/T〉2,then the manufacturer＇ s and the retailer＇ s logistics strategy are both logistics outsourcing, and the supply chain is stable; if 1〈T/T〈√12/5 then the manufacturer＇s logistics strategy is inconsistent with the retailer＇ s, with the manufacturer＇s optimal logistics strategy being lo- gistics outsourcing （self-logistics）, but the retailer＇s being self-logistics （logistics outsourcing） if the manu-facturer （retailer） is the dominant enterprise. （2） For the four combinations, if then themanufacturer dominant and self-logistics （retailer dominant and self-logistics） mode is better than the manufac- turer dominant and logistics outsourcing （retailer dominant and logistics outsourcing） mode. If T/T 〉 √12/5,then the manufacturer dominant and logistics outsourcing （retailer dominant and logistics outsourcing） mode is better than the manufacturer dominant and self-logistics （retailer dominant and self-logistics） mode.
