Abstract: Aiming at the supplier's development decision problem oriented to multi-manufacturer, a two-stage non-cooperative game model which composed of a supplier and two manufacturers was proposed under the situations that the supplier made the optimal development decision based on generic technologies and specific technologies. By comparing the supplier's maximum profits of these two optimal decisions, the respective dominant intervals as well as the conditions which made the two maximum profits be equal were obtained. Furthermore, the influence of supplied component's unit cost, supplied component's price, products'substitution rate and development cost fluctuation on supplier's optimal development decision under these two situations was discussed, and the corresponding numerical solutions were given. It showed that the optimal development degree and the maximum profits with different development decisions were negative correlated with supplied component's unit cost, supplied component's price, products substitution rate and development cost fluctuation, but the supplier's optimal development degree was positive correlated to supplied component's price. With the increasing of supplied component's price, the supplier's maximum profits was increased first and then decreased.
