Research Of Technology Innovation Diffusion And Capture Based On The Innovation Ecosystem

China has spent about 30 years to finish its industrialization development process which the developed countries has worked with it for nearly 100 years, but we also face the internal and external problems and the strong constraints of energy and resources. Thus, by carrying on independent innovation, enhance national innovation capability is the key to ensure the future economic development of our country. At the same time, modern enterprise’s innovation activities has already shown obvious trend of agglomeration, industry competition is gradually manifested as the competition between innovation populations or innovation ecosystems representing by innovation platform and technical standards. In this context, this paper based on innovation ecosystem theory, analyze technology innovation diffusion and capture has important theoretical and practical significance.First, summarize the concept of innovation ecosystem, technology innovation diffusion and technology innovation capture from different perspectives,analyze the related theory research progress at home and abroad and pointed out the paper’s research direction.Secondly, on the basis of investigation and theoretical inheritance,build a theoretical model of innovation ecosystem from the formation process of system and components, etc. And note that innovation ecosystem is a ecological complex adaptive system within a certain range of time and space, system subjects such as the enterprises, universities, research institutions, financial institutions, intermediary institutions and government interact with each other to form a stable innovation network, between the subjects and the innovation environment there is ongoing exchange of knowledge, talent, capital and information and the system is work to promote innovation emerge.On the basis of putting forward the concept of innovation potential, explain the connotation of technology innovation diffusion and technology innovation capture. Point that the position of the diffusion subject and the capture subject in the innovation system is determined by its initial innovation potential, the process of diffusion and capture is for the subjects to strengthen accumulation and improve innovation potential through the two paths of technology innovation diffusion(divergence and convergence). In this process, the relationship between the two kinds of subjects could transform from commensalism or parasitism to mutualism. Then analyze the evolution of innovation ecosystem by the logistic model and divide the system innovation development stage.Finally, take Zhongguancun innovation ecosystem as a case, analyze the system’s main innovation populations as well as the material and energy flow status quo, quantitatively measure the innovation evolution process of the system. On the basis of theoretical analysis and case summary, put forward some suggestions to promote the development of innovation ecosystems.The innovations of this paper can be expressed as follows: study technology innovation diffusion and technology innovation capture in innovation ecosystem from the perspective of innovation potential by introducing the theory of ecology, system science and enterprise competence. Enrich and develop the connotation of the innovation ecosystem as well as the related research of technological innovation diffusion.
