Abstract: The continuous evolution mechanism of innovation is always the focus among academic, business and government. In this study, the object of innovation ecosystem is the key point which we understand continuous evolution mechanism of innovation ecosystem, we think that the object of innovation ecosystem changing and evolving the innovation ecosystem continuing evolution. Based on the government and firm view, we conclude four models of continuous evolution ecosystem. Namely, governments, as the main body of area-level and national-level innovation ecosystem, can set the object, change the environment and ensure the evolution process. On the other hand, firms always adjust the strategy and open the capability boundary to design the object of innovation ecosystem. So, beyond the interactives of firm-level innovation ecosystem and focus on the objects of different levels innovation ecosystem will help us get more insights for continuation evolution of innovation ecosystem.
