Abstract: In order to achieve sustained competitive advantages, the third-party platform enterprises of the sharing economy would actively carry out competitive and complementary strategic co-operations with other enterprises. By using the evolutionary game method, this paper constructs the evolutionary game models of these two kinds of strategic cooperation and analyzes the stability and performance of each strategic choices and strategic cooperation. The results show that the stability of the strategic cooperation system of the sharing economy is relatively fragile, that the strategic choices of each side will be influenced by such factors as the extra gain of strategic cooperation, cooperative costs, the ratio of income distribution and the risk of resources suitability, etc., which will ultimately affect the final results of strategic cooperation. By constructing a sound strategic cooperation mechanism, the cooperation costs and innovation losses in the strategic cooperation can be reduced. At the same time, we should strengthen the value recognition of both sides of strategic cooperation and carry out the pre-evaluation on the resources invested, so as to reduce the risk of resource suitability.
