Abstract: Creating innovation ecosystem with technology standard as a link helps promote collaborative R&D and optimize resource allocation within the system, which provides a new path for value co-creation of firms in the innovation ecosystem. Analyzing form the two-dimensional of “product market-technology market”, this paper wants to explore the deep-seated mechanism between China's information industry listed firms’ strategy of creating the technology standardization innovation ecosystem and their sales growth. The study found that creating technology standardization innovation ecosystem significantly couples with the firm’s strategy of core-technology development and marketing behavior. Hi-tech firms create technology standardization innovation ecosystem, which would improve their technology-dependent system, stimulate the direct network effect under the same technology paradigm, and then make the firms’ core-technology transform to accepted products in the market. The technology standardization innovation ecosystem also helps stimulate indirect network effect by coordinating the development of complement technologies, which contributes to strengthen the firms’ marketing effect and then promotes sales growth.
