With the fast growth of science and technology, technology innovation is becoming the driver and motivation of many countries, regions and enterprises. Because of the limitation of human resource, material and capital in the process of self-innovation, more and more companies realized that it is a good way to share the resources and shoulder the risks by cooperating in innovation researches. However,40%-70% of co-operated R&D failed mainly due to spillover, the profit allocation model in improper alliance.This paper takes R&D partners as the object. R&D partners are the partnership established by several individual companies to achieve the common purpose. Based on knowledge spillover, Coalition Structure and the profit allocation model, to analysis the alliance invest strategies. Hope this will help to improve the invest volume of alliance members, decrease the speculate behaviors and increase the success ratio of alliance.This paper firstly makes research on related articles, then sum up the knowledge spillover models and R&D Alliance types, analysis the importance of R&D Alliance profit allocation models. Based on these analysis, working on the Netlogo,this paper compares the different effects of spill-over and non-spill-over, the Alliance members'invest strategies in different Alliance and profit allocation models, and reach the influence of spillover, alliance and profit allocation models to the alliance members'investment strategies. The results show that knowledge spillovers can reduce speculate behavior and improve the investment volume. When the alliance profit is small, alliance and the allocation model influence the investment strategies very conspicuously. In Alliance, focused R&D is better than the other R&D alliance. In the profit allocation model, the investment ratio model is better than average allocation model. When the total profit is big, spillover, alliance and profit allocation model have no big influence to the Alliance members'investment strategies. And in this situation, the alliance should take the average allocation model to improve the success opportuinities.
