Abstract: 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.

Key words: advanced producer service (APS), Chengdu-Chongqing region, urban network system
