In the twenty-fifth year of the Republic of China (1936), Jiangbei, Bishan and Baxian towns and townships were zoned, and the Jialing River Three Gorges Rural Construction Experimental Zone was established and set as a first-class county. During the Anti-Japanese War, the National Government clearly designated Chongqing as the capital. Because of its beautiful scenery, Beibei is only a few tens of kilometers away from the urban area, and it is accessible by Jialing River waterway and Beiqing Highway, so it was quickly identified as an important resettlement area. For a time, in Beibei and its nearby towns, hundreds of government agencies, scientific research institutions, universities and cultural units moved in, and thousands of politicians, scientists, educators and literary artists gathered. Beibei is famous from now on, and it is known as "the capital city" and "the small capital city". Beibei has also become an important cultural area in the rear area.

In the 31st year of the Republic of China (1942), in order to adapt to the development situation of Beibei in wartime, the Sichuan provincial government reported to the Executive Yuan of the National Government for approval, and changed the Jialing River Three Gorges Rural Construction Experimental Zone into Beibei Administration, which was under the leadership of the Sichuan provincial government and supervised by the Third District Commissioner's Office. At this point, Beibei was listed as a formal administrative region, and its administrative authority was further expanded. With the increase of population and the strengthening of urban management, urban construction is also accelerating. Large-scale trench filling and flood control, sewer construction and reconstruction, road widening were carried out, and new roads such as Zhongshan, Zhongzheng and Linsen were built one after another. With the continuous expansion of urban area, the appearance of towns has been greatly improved. It gradually developed into satellite towns with a certain municipal foundation, complete public facilities and beautiful urban environment, and became a model of urban development in the western region during the Republic of China.

Beibei during the Anti-Japanese War was not only an important cultural area in the rear area, but also an important energy base, textile industry base and experimental base of some important undertakings in Chongqing. According to the statistics of 1945, there are more than 60 coal mines in Beibei, such as Tianfu, Baoyuan, Huaying, Quanji, Fuxinglong and Sancaisheng. There are 7 special coal docks, more than 30 coal storage yards/kloc-0, more than 20,000 coal employees and an annual output of more than 700,000 tons of raw coal.
