摘　　要：构造了产品不完全同质条件下空间差异化的2阶段动态博弈模型,证明了即使在线性交通成本、消费者均匀分布等条件下,在产品不同质而导致产品总效用不同的双寡头市场上,企业的最优选择策略既不是最大差异化也不是最小差异化.最小差异化往往带来恶性价格竞争,而实行差异化又需要成本;最大差异化也不是所有情况下的企业的最优选择策略,企业应选择"适度差异化"策略.并且进一步讨论了交通费用剩余、垄断限价和共谋等相关问题.A dynamic two-stage game model with spatial differentiation is proposed for products with incomplete homogenous. It is proved that the optimal strategy, in the duopoly market with unequal gross utilities derived from incomplete homogenous products, is neither maximum nor minimum differentiation, if the transportation cost is linear and the customer is uniformly distributed. The players are suggested to choose moderate spatial differentiation strategy because the minimum differentiation will result in intensive price struggle and maximum differentiation strategy will cost resource. The other problems investigated here include transportation fee balance, monopoly pricing and collusion.
