Spatial pattern of cross-city medical network and supply-demand relationship of medical facilities in China:Based on cross-city medical internet data
The gradual scaling and normalization of regional sharing in medical facilities,characterized by cross-city medical treatment,has been observed,but there is a lack of theoretical and methodological exploration in existing research on the supply and demand relationships of these facilities.This study builds a detailed framework for the supply-demand relationships of medical facilities focused on regional sharing,grounded in the Homo-Urbanicus theory and social network analysis.It utilizes extensive internet-based medical treatment evaluation data from 2021 to 2022 to construct an cross-city medical network.The study follows the trajectory of"spatial pattern of cross-city medical network-supply and demand relationships of medical facilities",and conducts extensive empirical research on a national scale.The findings reveal that:(1)The supply of cross-city medical treatment in China exhibits a"dual-core and multi-center"spatial distribution,with Shanghai and Beijing,along with other provincial capitals,acting as supply centers connected to surrounding high-demand counties and cities,forming multiple single-center agglomeration patterns.(2)The service areas of medical facilities in China comprise five primary service regions(North China-Northeast China,East China,South China,Northwest China,and Southwest China)and 21 secondary service regions.This pattern generally follows provincial administrative boundaries,with some notable exceptions.(3)There is a higher coefficient of variation in medical treatment activities in Shanghai-Zhejiang-Jiangsu-Anhui,Sichuan-Tibet,and Shaanxi-Gansu-Qinghai regions(ranging from 3.860 to 3.716),and a lower coefficient in Ningxia,Shandong,and Fujian(ranging from 2.942 to 2.299).The supply and demand compatibility is higher in regions like Shanghai-Zhejiang-Jiangsu-Anhui,Beijing-Tianjin-Hebei-Shanxi-Inner Mongolia,Guangdong,Hubei,and Shaanxi-Gansu-Qinghai(ranging from 0.964 to 0.839),and lower in Hainan,Jiangxi,and Xinjiang(ranging from 0.453 to 0.41).This has resulted in two patient influx regions(Shanghai-Zhejiang-Jiangsu-Anhui,Beijing-Tianjin-Hebei-Shanxi-Inner Mongolia),four balanced regions(Guangdong,Shaanxi-Gansu-Qinghai,Hubei,Sichuan-Tibet),and fifteen outflow regions.This paper offers a framework for effectively interpreting the characteristics of supply-demand relationships of medical facilities at a regional scale,revealing the spatial pattern of inter-city medical treatment and its representation of supply and demand relationships.This contributes to addressing the gap in current research on inter-city medical treatment phenomena and the perspective of regional sharing,and can support the optimization of regional medical resource allocation.
