中国数字经济与医药制造业发展的耦合协调发展及时空演变分析OA

Objective To investigate the coupling coordination relationship between the digital economy and the pharmaceutical manufacturing industry in China,as well as their spatiotemporal evolution characteristics.Methods Based on provincial panel data from 30 Chinese provinces(autonomous regions and municipalities)between 2013 and 2023,a comprehensive evaluation index system was constructed.Empirical analysis was conducted using the coupling coordination degree model and spatial autocorrelation analysis.Results The average coupling coordination degree between the digital economy and the pharmaceutical manufacturing industry in China increased from 0.254 in 2013 to 0.392 in 2023,indicating an improvement from moderate dysfunction to mild dysfunction and reflecting a steady enhancement in the overall coordination level.However,significant regional disparities were observed:the coordination degree in the eastern region rose from 0.347 to 0.512,progressing from mild dysfunction to a state of marginal coordination;the central region exhibited the fastest growth rate(76.5%),increasing from 0.238 to 0.420;while the western and northeastern regions,despite rising from 0.183 and 0.235 to 0.286 and 0.328,respectively,remained in a state of mild to moderate dysfunction.Spatial analysis confirmed a significant positive spatial correlation in the coordinated development of the two systems,with local spatial analysis identifying a distinct pattern of coexisting"high-high"agglomeration(Beijing-Tianjin-Hebei,Yangtze River Delta,and Pearl River Delta)and"low-low"agglomeration(concentrated in parts of western and northeastern China).Conclusion While the coupling coordination between the digital economy and pharmaceutical manufacturing in China has generally improved,regional development imbalances remain prominent,showing a gradient pattern of"eastern region leading,central region rising,western and northeastern regions lagging".It is recommended to promote high-quality coordinated development through differentiated policies,technological innovation,institutional optimization,and cross-regional collaboration.
