Abstract:Innovation integration is an important mission for the construction of city cluster type independent innovation demonstration zone. Taking Sunan National Innovation Park as an example, this study defines the connotation of regional innovation integration in five dimensions, such as space, subject, object, environment and results, and analyzes the advantages and shortcomings of its innovation integration from two perspectives, namely, the promotion of Sunan’s own integration work and the horizontal comparison of innovation performance, by benchmarking with the four independent innovation demonstration zones built before it. The results show that the innovation integration work promoted from the top down at the provincial level has achieved certain results, but due to the low participation of cities and high-tech zones, the innovation development performance of Southern Jiangsu still has a large gap compared with the independent innovation demonstration zones such as Zhongguancun, even though the resources of the nine national high-tech parks have been integrated. Accordingly, insights are obtained from the joint planning of integrated innovation space layout, joint efforts to enhance the main innovation capacity,joint concentration of innovation resources and elements, joint shaping of open and integrated dual-innovation ecological environment, and joint research and sharing of regional scientific and technological achievements.
