摘　　要：都市圈作为新型城镇化进程中承上启下的空间载体,是城市网络结构研究的重点区域。以徐州都市圈为研究对象,基于夜间灯光数据、人口普查数据和企业总部分支等多源数据,从规模联系和功能联系视角揭示2010—2020年都市圈网络结构演变特征,并探讨其潜在的多中心趋势和优化路径。研究发现:①徐州都市圈县区间规模联系强度提升明显,呈现出中心城市放射型规模网络结构,规模联系网络密度和中心城市的核心地位不断增强,不均衡性明显。②受限于县区间的同质化竞争和省界分割,中心城市的三产职能优势尚未凸显,跨省级行政区的企业合作联系有待加强。③徐州都市圈规模网络与功能网络均呈现单极化特征,但具有潜在的多中心趋势,且功能网络的多中心发展滞后于规模网络,多数县区功能联系滞后于规模联系。该文对培育型都市圈规模与功能联系协同发展路径的探索,可为发展相对滞后地区解决跨区域要素流动障碍问题提供理论参考和案例借鉴。Taking Xuzhou metropolitan area as the research object,based on multi-source data such as nighttime light images,population census data,and enterprise headquarters and branches,this paper reveals the evolution characteristics of the network structure of Xuzhou metropolitan area from 2010 to 2020 from the perspectives of scale and function connections,and explores its potential polycentricity and optimization paths.It is found as follows.①The intensity of scale connections between counties and urban districts in Xuzhou metropolitan area has significantly increased,showing a radial scale network structure of the central cities.The density of scale connection networks and the core position of the central city are constantly increasing,and the uneven network characteristics are more obvious.②Due to the homogenization competition between urban districts and counties,as well as the division of inter provincial administrative regions,the function advantages of the tertiary industry in central cities have not yet been highlighted,and the cooperation and connection between enterprises across provincial administrative regions need to be strengthened.③The scale network and functional network of Xuzhou metropolitan area both exhibit unipolar characteristics,but have a potential multi-center trend.The multi-center development of the functional network lags behind the scale network,and more than half of the county and district functional connections lag behind the scale connections.This paper explores the coordinated development path of scale and functional connections in cultivated metropolitan area,which can provide theoretical reference and case study for solving the problem of cross regional factor flow barriers in relatively underdeveloped areas.
