Abstract: According to inconsistent characteristics of durable goods and consumables market, the two-stage Stackelberg game model and customer segmentation model, respectively, were used to study the durable goods and consumables market. We find that inter-temporal in-consistence has significant influence on market competition. In the durable goods market, the manufacturer can use incompatible strategy to lock consumers, resulting in the pattern of the strong being strong forever. Otherwise, the market competition is more intense. In the consumable market two-stage production, when there are only new manufacturing consumables and the coexistence of new consumables and re-manufacturing consumables, the result of the market competition is different. The research has showed that, in the inter-temporal market competition of durable goods and consumables, the combination of two models can better explore the competition pattern of product market, and is the effective method to study the competition of inter-temporal product market.
