Abstract: As the industrial boundaries getting fuzzy, the tendency of technological convergence is becoming more and more obvious. This new competitive-cooperative trend pushed by technological convergence compels enterprises to think over their strategies of product innovation once again. Based on redefining the concept of technological convergence, this paper tries to analyze the three major innovation modes of technological convergence in IT enterprise, i.e. technology sharing, technology merger and acquisition, and technology licensing. It also analyzes the influence of technological complementarities, absorption capacity of enterprise, technology spillover coefficient and innovation coefficient on corporate equilibrium cost, equilibrium investment in R&D, equilibrium output and profit which are involved in the technological convergence and innovation by constructing the relative game models. Finally, it makes a comparison between the technological contribution and the equilibrium solution of equilibrium output and equilibrium profit under the three innovative methods.

Key words: technological convergence; IT enterprises; innovation mode
