Abstract:Based on the theory of innovation ecosystem and innovation niche suitability, this paper compares the industrial innovation niche suitability of 31 provinces in China, and measures the index of innovation ecosystem and innovation evolution momentum,to find out and sort out the status of industrial innovation development, and summarize the status and challenges of industrial innovation niche and related indexes in northeast China. The conclusions are as follows: the overall innovation niche level in Liaoning Province is higher, but the evolution potential energy is weakening gradually; the overall industrial innovation niche in Jilin Province is backward, and the innovation resources and their integration ability are generally insufficient; the overall advantage of industrial innovation niche in Heilongjiang Province is low, but the evolution kinetic energy is large. The innovation drive of northeast industry urgently needs to construct the industrial innovation ecosystem based on the niche suitability of innovation, especially to realize the innovation linkage effect of the three industries in northeast China from the strategic level. From the perspective of optimizing the allocation of innovative resources, the innovation niche level of northeast industry is promoted as a whole.
