Abstract: As the knowledge update cycle shortened and the rise of newly science and technology countries,by bringing newly technology countries into their original relatively closed innovation system,developed countries can achieve the goal lowering challenges from newly technology countries and utilizing innovation elements from newly technology countries.Unlike the previous study of global R&D network division,in view of the judgment that,the production control of developed countries are in transition from general industry R&D field to the core technology R&D field,this paper studies the division of global R&D network.Based on the analysis of the IT industry innovation value chain and profit distribution of IT products,this paper found that,the core technology affecting the direction of international technical progress and the system capabilities to integrate global R&D innovative elements that developed countries mastered have provided theoretical basis for the construction of global R&D network which can affect and control global production.The R&D monopoly profits that enterprises from developed countries occupied create the profit foundation,making the production control of developed countries from general industry R&D field to the core technology R&D field the transition.
