沿海地区经济高质量发展、海洋经济与交通状况耦合协调的时空演化及影响因素
Spatiotemporal Evolution and Influencing Factors of Coupling Coordination Among High-Quality Economic Development,Marine Economy,and Transportation Conditions in China's Coastal Regions
摘要
Abstract
Against the background of deepening land-sea coordination,clarifying the interactive relationships among high-quality economic development,marine economy,and transportation conditions is of great significance for promoting sustainable development in coastal regions.Based on the panel data of 11 coastal provinces(autonomous regions and municipalities)in China from 2013 to 2022,this study empirically analyzes the spatiotemporal evolution characteristics and influencing factors of the coupling coordination relationship among these three major systems,using a coupling coordination model and a Radial Basis Function(RBF)neural network.The results show that:① the development levels of the three systems in coastal provincial-level regions are unbalanced with significant inter-provincial disparities—the indices of high-quality economic development and marine economy have steadily increased,yet the inter-provincial gap has continued to widen;although the inter-provincial disparity in the transportation condition index has gradually narrowed,polarization remains evident;② regional development is uncoordinated—the eastern marine economic circle significantly outperforms the others in various indicators,while both the southern and northern marine economic circles fall below the overall average level of China's coastal regions;③ the coupling coordination degree of coastal provincial-level regions is generally low but shows an upward trend,with continuously expanding inter-provincial disparities—Guangdong,Shanghai,Jiangsu,and Shandong are in the barely coordinated stage,whereas Liaoning,Hebei,Tianjin,Guangxi,and Hainan remain in a state of mild imbalance;④ the coupling coordination level exhibits no significant spatial correlation;transportation condition factors play a leading role in coordinated development,while the ratio of marine aquatic products to permanent resident population,inland waterway density,and the proportion of gross marine product to regional gross domestic product are the key influencing factors.This study may provide a scientific basis and practical reference for exploring high-quality economic development pathways in coastal regions and promoting coordinated land-sea governance.关键词
