SPATIAL AGGLOMERATION CHARACTERISTICS AND FORMATION MECHANISM OF KNOWLEDGE-INTENSIVE MANUFACTURING INDUSTRIES IN THREE MAJOR URBAN AGGLOMERATIONS IN CHINA:BASED ON BIG DATA ANALYSIS OF SCIENCE AND TECHNOLOGY-BASED ENTERPRISES
SPATIAL AGGLOMERATION CHARACTERISTICS AND FORMATION MECHANISM OF KNOWLEDGE-INTENSIVE MANUFACTURING INDUSTRIES IN THREE MAJOR URBAN AGGLOMERATIONS IN CHINA:BASED ON BIG DATA ANALYSIS OF SCIENCE AND TECHNOLOGY-BASED ENTERPRISES
The study examines the clustering characteristics and formation mechanisms of knowledge-intensive manufacturing industries at various scales.The results show that:l)The computer industry has the highest agglomeration intensity,and the agglomeration intensity of each industry in Beijing-Tianjin-Hebei is higher than that in the Yangtze River Delta and Pearl River Delta regions.2)At the city cluster scale,indus-tries are primarily concentrated within a 100 km radius.3)City-scale industries are mostly concentrated within a 40 km radius,with a small number of industries clustering in peripheral areas.The Beijing-Tianjin-Hebei region exhibits a'spreading type'agglomeration,while the Yangtze River Delta is of'local type'and'multi-centre type',and the Pearl River Delta is of'multi-centre type'.4)The scale of city clusters is deter-mined by regional resource endowment and comparative advantages.The characteristics of agglomeration in each city scale vary depending on spatial differences in production costs,industrial policies,and local protec-tionism.
