The multiscale analysis of the spatial pattern of regional innovation hubs in China:A perspective from high-tech enterprises
With the unprecedented intensification of technological innovation,innovative ele-ments are constantly gathering,and several innovation hubs are emerging.The spatial pattern of China's regional innovation hubs has become an essential topic in theory and practice.Based on the data from high-tech enterprises,this paper attempts to identify the spatial pattern of China's existing regional innovation hubs by comprehensively using the DO index and natural break point method.The findings show that:(1)The spatial pattern of comprehensive innovation hubs and service innovation hubs is highly overlapping,forming a"three-legged tripod"spatial pattern in the Yangtze River Delta,Pearl River Delta,and Beijing-Tianjin-Hebei city clusters.(2)The manufacturing innovation hubs have formed a"two-pole"pattern dominated by the Yangtze Riv-er Delta city clusters and the Pearl River Delta city clusters.(3)The innovative elements in the Yangtze River Delta and Pearl River Delta exhibit a high-high agglomeration feature,while other areas still mainly exhibit a high-low agglomeration,and the overall national innovation level still needs to be improved.(4)Considering all three types of innovation hubs,the network of innova-tion hubs composed of provincial central cities has taken shape,and the three major city clusters are the core nodes of the innovation highland network.
