在交通快速化发展背景下,以海峡西岸经济区20个设区市为研究对象,利用社会网络分析方法分析2007年以来海西区市域经济网络联系的特点及其形成机制。研究结果表明:(1)海西区区域经济联系的网络密度不断提高,网络联系逐渐向多向化、稠密化、纵深化、均衡化方向发展,在空间上形成了明显的“核心—边缘”网络结构,福州、厦门、泉州、漳州、温州等设区市一直处于网络中心,丽水、衢州、鹰潭、梅州、潮州等设区市则处于网络边缘;(2)E-I派系结构分析表明受行政隶属关系的影响,海西区4省间存在较为明显的“行政派系结构”但有缓和趋势,经济联系由封闭逐渐趋于开放,各省份间经济溢出效应还有较大提升空间;(3)QAP分析表明收入水平、城镇化水平、空间近邻、时间距离等因素对海西区经济网络联系有显著影响。
Under the background of rapid traffic development, taking the 20 districts and cities in the economic zone on the west side of the Straits as the research objects, this paper analyzes the characteristics and formation mechanism of the economic links in the western region of the Taiwan Straits since 2007 by using social network analysis methods. The results show that: (1) The network density of regional economic ties in the Hercynian continued to increase, and the network connections gradually developed towards more diversification, denserness, verticalization and equalization, forming a distinct “core-periphery” (2) The analysis of the EI factional structure shows that the administrative structure of the Faction, such as the network structure, Fuzhou, Xiamen, Quanzhou, Zhangzhou and Wenzhou, has been at the center of the network. Lishui, Quzhou, Yingtan, Meizhou and Chaozhou, Subordinate relations, there is a more obvious “administrative factional structure” among the four provinces in the western region of Haixi. However, there is a trend toward easing economic ties gradually becoming more and more open from the time of closure and there is still much room for improvement in the economic spillover effect among provinces. ) QAP analysis shows that income, urbanization level, spatial proximity, time distance and other factors have a significant impact on the economic network connection in the region.
