RESEARCH ON AGGLOMERATION CHARACTERISTICS AND PROXIMITY MECHANISMS OF INNOVATIVE ENTERPRISES AT MESO AND MICRO LEVELS:BASED ON THE EMPIRICAL EVIDENCE OF FOUR TYPICAL CITIES IN THE YANGTZE RIVER DELTA REGION
In light of the reconstruction of the logic of spatial use under the innovation economy,this paper seeks to analyze the agglomeration and location selection of innovation elements in cities.This paper first develops a framework to analyze the agglomeration and location selection of innovative enterprises,and use the data of small and medium-sized innovative enterprises and questionnaire survey to study four typical innovative cities in the Yangtze River Delta-Shanghai,Nanjing,Hangzhou,and Suzhou-so as to understand the new changes and demands of the spatial use of innovation elements.The following conclusions are drawn.(1)Agglomeration trend:in the context of urbanization driven by both inner-city regeneration and new city construction in China,the agglomeration of innovative enterprises exhibits the characteristics of returning to urban centers and growing in the suburbs.The latter,to some extent,has matched the spatial demands of innovative talents who prefer the emerging suburban scientific parks featuring low density and high space quality.(2)Structural evolution:the agglomeration structure of innovative enterprises coincides closely with the spatial transformation and functional evolution of cities.The division of regional functions and spatial structure of cities exert profound impacts on the agglomeration of enterprises.The concentration intensity of innovative enterprises decays from the center to the periphery,forming a core-edge structure with a radius of 1-3 km.(3)Location selection logic:in addition to traditional factors such as policy support and industry cluster,innovative enterprises not only gather towards young industrial clusters and application-oriented research clusters,but also manifest a clear urban life orientation.Soft factors such as space quality and innovation milieu have become high-level demands that cannot be ignored.
