In the model, each supplier provides a complementary component to the manufacturer. We derive the optimal strategy of each enterprise under the wholesale-price contract, and find the manufacturer’s optimal order quantity depends on both the number of components and the manufacturer’s loss-aversion coefficient. Moreover, by using numerical analysis, we show that: (1)For a given number of components, as the manufacturer’s loss-aversion coefficient increases, the manufacturer’s optimal order quantity decreases; as the number of components increases, the impact of manufacturer’s loss-aversion coefficient on manufacturer’s optimal order quantity increase. (2)For a given manufacturer’s loss-aversion coefficient, as the number of components increases, the manufacturer’s optimal order quantity decreases; as the manufacturer’s loss-aversion coefficient increases, the impact of components’ number on manufacturer’s optimal order quantity increases.
