复杂网络在巨型城市区域中的应用研究尚处于初步阶段，为了弥补现有城市网络研究工具的不足，以点度分布、链接方向、节点匹配等统计量来度量巨型城市区域的网络联系特征，在前人研究的基础上将样本对象扩展到了所有具有母－子关系的多区位企业，形成企业总部－分支机构的权重型关系数据，并以珠三角区域9 个地级城市为研究对象，运用复杂网络工具分析珠三角区域空间链接的属性特征．节点的匹配性表明，珠三角区域的功能联系有着一定的同向匹配特征，规模指向较为突出; 链接方向显示了巨型城市区域内部价值区段空间组合的网络表征．

The research on the application of complex networks to mega city region is still in an initial stage at pres-ent.In order to remedy the shortcomings of existing analysis tools in the city network field,some statistics,such as the node degree distribution,the linkage direction and the nodal assortativity are employed to estimate the network features of mega city region.Then,based on the related researches of other scholars,the samples are enlarged to all multi- location corporations with the relation of ownership to obtain the weighted relation data of enterprise head-quarter and subsidiary.Finally,by taking nine prefecture cities in the Pearl River Delta as the research objects,the corresponding attributes of the spatial linkage in this area are analyzed with the above- mentioned statistics.According to the nodal assortativity,is found that the functional linkage in the Pearl River Delta is assortative and is related to city size.Moreover,the linkage direction of network represents the characteristic of value chain in mega city region.
