Research on the Dynamic Evolution and Influencing Factors of the Coupled and Coordinated Development of Digital Economy and Port Economy:A Case Study of Nine Port Cities in Yunnan Province
摘要
Abstract
Based on panel data from nine border cities in Yunnan Province between 2011 and 2022,this study uses the Coupling Coordination Degree Model,Relative Development Degree Model,Gaussian Kernel Density Estimation,and Geographical Detector Model to examine the dynamic evolution and influencing factors of the coupling and coordinated development level of the digital economy and border economy in Yunnan Province.The results show that the overall development level of the digital economy and border economy in Yunnan Province continuously improves from 2011 to 2022,with significant differences in growth rates among various border cities.The coupling coordination degree between the digital economy and the border economy exhibits a trend of annual increase.During the study period,regions such as Honghe,Wenshan,Xishuangbanna,and Dehong have relatively high development levels,maintaining a leading position in border economy development,while Kunming,Baoshan,Lijiang,Pu'er,and Lincang have relatively lower development levels.The peak pattern of the coupling coordination degree shows a"gradual decline-rise-decline-sharp rise"characteristic,with a noticeable bimodal feature and a phenomenon of two-level differentiation.Geographical detector factor detection results show that innovation capability has the most significant impact on the coupling and coordinated development of digital economy and port economy in Yunnan Province.The explanatory power of the interaction between any two factors on the coupling coordination degree is higher than that of a single factor,and nonlinear enhancement dominates,with no weakening or independent relationships observed.关键词
