Abstract: Chongqing region became the key area of thirdline construction because of the important strategic position. Under the macro layout policy of “relying on mountains, spreading and concealment”, the heavy industry in Chongqing area during the thirdline construction was distributed along the Yangtze river with five main urban areas such as Shapingba, Yuzhong, Nanan, Jiangbei and Jiulongpo as the centers, forming three distribution areas, that is the northwest Chongqing, the central of Chongqing and the southeast of Chongqing. The layout of thirdline construction enterprises were too centralized and scattered. The distribution of thirdline construction enterprises changed the industrial layout of Chongqing, making the gravity of industrial development in Chongqing expand from the main urban areas to Jiangjin, Nanchuan, Qijiang, Yongchuan, Changshou and other places along the river gradually. At the same time, the distribution of thirdline construction enterprises made the core area and the radiating circle of urban development of Chongqing expand from the main urban area to other places along the Yangtze river and equalize the regional structure of urban system of Chongqing by promoting the rise of a number of industrial towns such as Beibei, Changshou, Fuling, Xipeng and other places.
