This article introduces the reaction degree coefficient and the influence coefficient, constructs the industrial contact intensity model, and analyzes the spatial network characteristics of industries in the Changjiang River Delta and Beijing-Tianjin-Hebei (BTH) metropolitan region through the model of industry contact intensity. It focuses on the difference between the two regions and research the formation of metropolis shadow. The results show: 1) the better the industries contacts among the cities in region, the higher the economy level of region; 2) the better the industries between central city and other cities in region, he higher the economy level of region; 3) from the perspective of industries spatial contacts, the weak industry contact between central city and outlying areas is the key reason for the metropolitan shadow’s formation.
