基于高级生产者服务业视角,建立了成渝地区17 个最小分析单元(FUR,Functional Urban Region) × 149家公司的量化矩阵,进行了基于服务值、连通性和网络性特征的分析,研究了成渝地区的城市网络体系结构及其特征。其中,FUR为重庆都市发达经济圈、渝西走廊地区和绝大部分地级市。结果表明：成都市和重庆都市发达经济圈在成渝地区城市网络体系中构成双一级核心;次核心绵阳市在显著连接数量上领先于除一级核心以外的其他城市或地区;其余城市或地区在城市网络中的地位虽略有差别,但相互联系,共同发展。成渝地区的生产者服务业发展还仅仅停留在起步阶段,基于高级生产者服务业视角的城市网络体系还处于初级阶段,尤其是成渝地区经济基础相对发达的城市并未连接成片,区域中心城市之间地域的经济联系比较落后。
Based on the advanced producer service research, we build a quantified matrix which includes all of the 149 companies located in the 17 smallest units for analysis (FUR), and gain the architecture and features of the urban network system of Chengdu-Chongqing urban agglomeration by analyzing the value, connectivity, and symmetrically and asymmetrically connected networks. FURs cover most of the prefecture level cities, and the Chongqing Development Economic Zone, and the Western Corridor. The results are drawn as follows. Chengdu and Chongqing Development Economic Zone constitutes a first level dual-core structure in the network of advanced producer services. Mianyang leads a number of connections among other FURs outside the first level. There are tiny differences in position and structure among other cities or regions in the Chengdu-Chongqing region, and they interrelate and develop together. The producer services of Chengdu-Chongqing region is at a preliminary stage and the urban network system based on advanced producer services is still in its infancy. Especially, the cities or regions which have developed economies are not connected and the eonomies in the areas between the regional central cities are underdeveloped.
