This article further analyses urban network evolution characteristics of the Yangtze River Delta region based on producer services industry from three aspects of the hierarchical change of the node city, the spatial evolution of the network pattern and the evolution of the urban function by using western research methods of Interlock Network,Standardized Residuals.The results show that: the urban network of Yangtze River Delta based on production service industry has a significant hierarchy structure, but the gap between the levels is gradually narrowing. The urban network has obvious order relation, but the traditional core area is spreading outward and the flattening trend is strengthened.There are obvious differences in the distribution of service functions. In addition to the legal and advertising functions,the gap between other service functions is gradually narrowing and the network connection is more fully.
