Abstract:Based on the modular perspective, this paper studies how equipment manufacturing enterprises realize key core technology innovation, and uses case study method to explore the motivation, process and results of S enterprises ' key core technology innovation. It is found that technological capability diversification, information technology development, cooperative innovation network, national development needs and market demand promote enterprises to realize key core technological innovation through modularization. Product modularization empowers the key core technological innovation of enterprises by connecting user needs and product characteristics, flexible combination and integration, independent production and quality control, sustainable maintenance and upgrading. Organizational modularization promotes the modular empowerment innovation of internal and external organizations by integrating innovation resources. In the process of innovation, product modularization promotes organizational modularization, and modular organization permeates the whole life cycle of modular products.
