Abstract Urban flows describes the basic activities of city, reflects the urban external services, and reveals the contacts between cites. And correlation between urban flows intensity and urban centrality shows that urban flows intensity is the quantitative index of urban external service functions. With the case study of 13 major urban agglomerations in China, this article analyses their urban flows intensity and structures, and discusses spatial distribution and growth situation of external services function in terms of urban flows. Research shows that the Yangtze River Delta, the Pearl River Delta, Beijing-Tianjing and Northern Hebei agglomerations have the most mighty external production services, which constitute the three major Chinese integrated production bases in service. Shandong peninsula, the middle-south part of Liaoning province agglomerations are the fourth and fifth production service bases in China, while the agglomerations in Midwest China has weaker external services functions. The Yangtze River Delta, Pearl River Delta agglomerations as national comprehensive external production service centers specialize in manufacturing. Beijing-Tianjing and Northern Hebei agglomerations specialize in the tertiary industry, while Shandong peninsula agglomerations form a national external production service centre mainly in the secondary industry.
