Abstract: With the accelerated development of globalization and the revolutionary advances of information technology, advanced producer services (APS) have become the main driving force of the region's economic growth and an important source of product innovation, and its positive role in the construction of urban network has gained extensive attention from scholars at home and abroad. By systemically analyzing the changes of the urban network research carrier, it can be found that the layout behavior of the producer services enterprises provides an important breakthrough point for the world's city network research. Meanwhile, due to the advantages of the relational data access, urban network construction from the perspective of producer services industry has become an important frontier of city research in the western countries. On the whole, the close correlation between the producer services aggregation and city level is an important foundation of network construction based on producer services, the acting forces of network construction includes the industry attributes of producer services, location selection of the producer services enterprise, and urban development conditions, such as innovative elements, technical facilities, etc. Through the detailed studies of network construction models, the network features, and the dynamic evolution, it can be found that the layout of producer services industry can be applied to the interpretation of urban network in China under the impact of globalization and informatization. Domestic scholars have recognized its importance, and current researches are focused on introducing the method, rather than being concerned with intrinsic mechanisms and evolution characteristics. As the division of labor in global industries deepens, China no longer just plays a role in manufacturing; the country's producer services will start to cluster in large scales. Domestic research on urban network based on producer services just started, and should be strengthened. Based on practical needs, this paper further proposes directions for future research. With China's more active participation in globalization, the theoretical framework of urban network based on producer services need to be established, the systematic studies of urban network based on producer services at regional level is certainly insufficient, and the driving mechanisms and future trends of the urban network require in-depth investigations.
