The Chengdu-Chongqing Economic Circle is an important center for promoting economic growth in the western region. Clarifying the driving force and restrictive factors of the urbanization development in Chengdu-Chongqing area is conducive to the further development of the region. First, this study uses piecewise linear regression to determine the characteristics of resource consumption. Then use Moran index to test the spatial agglomeration relationship. Finally, combining the characteristics of resource utilization and spatial agglomeration effects in Chengdu-Chongqing area, 143 cities are classified. The results show that: (1) The Chengdu-Chongqing economic circle as a whole presents the characteristics of high resource utilization pressure and abundant resource content. (2) In areas with obvious agglomeration effects, most cities have less pressure on natural resources, lower resource levels, less investment in environmental protection, and higher levels of urbanization. (3) The pressure on the use of natural resources and the expropriation of environmental protection measures are matched with each other in areas with significant concentration. (4) With the development of cities, the characteristics of resource utilization in various regions will tend to be unified. Researching and exploring the characteristics of resource utilization in the Chengdu-Chongqing Economic Circle will help the government to formulate relevant policies to ensure the coordinated development of regional ecology and the city.
