Abstract: From the micro-enterprise perspective, 100 equipment manufacturing industries and 100 space units of the Yangtze River Economic Belt were selected as research samples. Based on the research methods of urban networks and the theory of complex networks, the hierarchical system, spatial pattern, network connections and complexity characteristics of the equipment manufacturing networks of the Yangtze River Economic Belt were explored. The research shows that there is a significant gap in the abilities of network organization of node cities, and a pyramidal hierarchical structure has been formed by four levels: regional, sub-regional, local, and sub-local. The organizational capabilities of the equipment manufacturing networks show significant unbalanced characteristics in space, which forming three core areas. The network of contacts generally shows a trend of gradual expansion from the Yangtze River Delta region to the middle and upper reaches of the Yangtze River. The whole structure of networks shows strong aggregation and connectivity, and there is a significant relationship between the characteristics of complex networks and the status of the urban networks.
