The spatio-temporal evolution characteristics and driving factors of digital technology application industry in the Chengdu-Chongqing Double-City Economic Circle
Industrial digitization is an important manifestation of the deep integration of digital economy and real economy.Based on a sample of 4348 digital technology application enterpris-es in Chengdu-Chongqing double circle from 2014-2023,the average nearest neighbor index,kernel density estimation,standard deviation ellipse and multi-distance spatial cluster analysis are used to portray the characteristics of the evolution of the spatial and temporal patterns of the digital technology application industry in Chengdu-Chongqing double circle,and a geographic probe model was used to explore the driving effects of various factors on the agglomeration de-velopment of the digital technology application industry in Chengdu-Chongqing double circle.The study finds that:① The number of digital technology application enterprises in the Chengdu-Chongqing Double-City Economic Circle has been increasing year by year,with the largest num-ber of small-scale enterprises,followed by micro,medium,and large enterprises.The coverage of enterprise distribution has been expanding year by year,presenting a spatial distribution char-acteristic of"agglomeration in the central urban area and gradient diffusion in the surrounding ar-eas".The overall distribution is highly consistent with the geographical pattern of industrial parks and higher education institutions.② The overall level of agglomeration has increased,showing a spatial evolution from"east(slightly south)to west(slightly north)".The transition from"monocentric dominance"to"bicentric radiation"gradually evolves into"polycentric diffu-sion".③ Taking Chengdu and Chongqing as the single-core and dual-core respectively,the peak concentration of digital technology application industry is 30 km,4 km and 50 km,and the optimal values of concentration are 270 km,130 km and 360 km.④ The economic base,market potential and policy guarantee factors are generally on the rise,while the human capital factors shows an inverted"U"shape.
