网络嵌入对中国沿海城市海洋经济外向服务功能的影响
Impact of Network Embeddedness on the Outward Service Functions of Marine Economy in China's Coastal Cities
摘要
Abstract
Under the background of the"space of flows"reshaping the spatial organization of the marine economy,it is crucial to identify the evolutionary characteristics and network-driven mechanisms of coastal city functions.Utilizing multi-dimensional flow data of the marine economy from Chinese coastal cities in 2017 and 2022,this study improves the outward service function measurement model by introducing a network efficiency factor.It classifies hierarchical echelons and factor-dominant types,and constructs a regression model to explore the influence mechanisms of network embeddedness on the outward service functions of China's coastal cities.The findings indicate that:(1)The outward service energy levels of coastal cities exhibit a significant"pyramid-shaped"echelon pattern;core cities are mostly characterized as multi-factor-driven,while middle-and-low-level cities rely on single factors.(2)Network embeddedness is the core variable driving functional improvement.(3)Structural advantage in the network triggers a"functional spillover and transfer loss"effect,exerting a negative impact on the functional enhancement of coastal hub cities.(4)Heterogeneity analysis reveals that the promotion effect of network embeddedness on lower-level cities is significantly superior to that on higher-level cities;integrating into the network is a key path for peripheral cities to achieve functional breakthroughs.关键词
