Research On Niche Suitability Of Regional Innovation In The Yangtze River Economic Belt

With the transformation and upgrading of China's economy,The driving force of economic development has shifted from traditional input to innovation.At the same time,with the acceleration of regional integration,The national macro strategy also emphasizes the integration of regional advantages.By gathering superior resources for innovation,Promoting the rational flow and efficient allocation of innovation resources,Regional independent innovation capability and regional collaborative innovation level can be promoted.In this context,regional innovation has gradually become a hot topic in academic research.Subsequently,the evolution and upgrading of innovation research paradigm and the development of regional innovation ecosystem research emerged.Regional innovation ecosystem emphasizes the interaction and symbiotic evolution of innovation elements from the perspective of ecology,and opposes the traditional "isolated island" innovative concept.Therefore,the regional innovation ecosystem regards the regional innovation activity as the overall behavior of the innovation subject and the innovation environment.As an inland river economic belt spanning three regions in China,the Yangtze river economic belt has the highest economic density except the open coastal areas.Therefore,it has important strategic significance.Under the background of innovation-driven and region-coordinated development,How to realize the orderly flow and efficient allocation of regional innovation resources in the Yangtze river economic belt with the guidance of the internal law and evolutionary logic of the regional innovation ecosystem is an important topic worth studying.In that context,based on the theories of ecology,system and complex system,the paper analyzes and constructs the structure model of regional innovative ecosystem from the perspective of ecological metaphor.The paper makes a descriptive analysis of the development status of the innovative ecosystem in11 provincial units of the Yangtze river economic belt,and forms an overall grasp of the regional innovative ecosystem in the Yangtze river economic belt from the theoretical and practical dimension.Then,on the basis of theoretical derivation of regional innovation ecosystem structure model,the paper further constructs a suitability index system reflecting the dynamic evolution relationship of regional innovation ecosystem based on the ERF model.The paper uses AHP-EM weighting model to modify the niche suitability model,uses demonstration to analyze the niche suitability and evolutionary momentum level of innovation in the Yangtze river economic belt,and analyzes the advantages and disadvantages of innovation resources in the Yangtze river economic belt.Finally,based on the above analysis results,the paper puts forward some policy Suggestions to improve the suitability of innovation niche in the Yangtze river economic belt.researches show that:(1)The level of innovation niche suitability in different provincesof the Yangtze river economic belt is obviously different,and the trend of polarization is gradually emerging.Among them,the suitability level of innovation ecological niche in jiangsu and hubei provinces is high and has maintained an obvious positive growth trend,while that of anhui province is backward and has maintained a negative growth state for a long time;(2)The niche suitability of innovation in the Yangtze river economic belt decreases from east to west.Among them,the downstream is the highest,the middle is the second,the upstream is the lowest,And all show obvious negative growth state.(3)Comparing the niche suitability and evolutionary momentum of innovation,The higher the niche suitability,the lower the evolutionary momentum,vice versa.In other words,the region with relatively backward niche suitability at present has greater potential for future improvement.Therefore,targeted innovation and optimization measures will produce more significant improvement effects on jiangxi,yunnan,guizhou and other provinces with low niche suitability;(4)In terms of the state of innovation resources,the Yangtze river economic belt has universal problems in innovation species,innovation connection and innovation function.Such as The development of dominant species of innovation is stunted,the support of market environment is insufficient,the access of public science and education resources is low,the transformation and commercialization rate of innovation achievements is low,the ability of independent innovation is weak and so on.By narrowing the gap between the actual ecological niche and the optimal ecological niche of the above innovation factors,the suitability level of the overall innovative ecological niche of the Yangtze river economic belt can be improved.Finally,according to the conclusion of this paper and the development of the Yangtze river economic belt,the paper puts forward the following Suggestions from the system optimization,mechanism design and platform construction three dimensions:(1)Cultivate innovative dominant species and create core competitive advantages;(2)Extend the innovative food chain and strengthen the internal and external connections of the system;(3)Establish resource sharing mechanism with complementary advantages;(4)build a diversified R&D investment mechanism;(5)Improve the market-oriented innovation driving mechanism;(6)Establish a technology innovation service platform;(7)Explore green services innovation fusion development platform.It is hoped to provide a feasible reference for improving the niche suitability of the innovation of the Yangtze river economic belt and enhancing the level of regional collaborative innovation of the Yangtze river economic belt.
