Abstract: Indigenous centralized R&D networks aimed at improving the innovation capacity of local firms are emerging in the face of global economic downturn. Based on the general path of complex product technological innovation capacity enhancement in latecomer countries, this paper divides enterprise technological innovation dimensions into technology imitative innovation and technology collaborative innovation, and then establishes a theoretical model of the impact of indigenous centralized R&D networks on enterprise technology innovation, and finally empirically analyses the proposed hypotheses by collecting 279 valid data from complex product enterprises. The study shows that indigenous centralized R&D networks improve both technology imitative innovation and collaborative innovation. And indigenous centralized R&D networks can better stimulate the technology collaborative innovation. Indigenous centralized R&D networks influence enterprise technology imitative innovation through network technology diffusion. Moreover, product modularity, as a moderator, positively affects the relationship between indigenous centralized R&D networks and technology imitative innovation. And technology legitimacy, as another moderator, negatively affects the relationship between indigenous centralized R&D networks and technology collaborative innovation. This study has enlightening significance for technology innovation in the field of complex products, especially for the question of how to utilize product modularity and technology legitimacy to enhance technology imitative innovation and technology collaborative innovation.
