According to the National Development and Reform Commission, the Beijing-Hebei-Tianjin hub consists of Beijing and Tianjin Municipalities, eight big cities in Hebei province - including Shijiazhuang, Baoding and Qinhuangdao - four urban nodes, including Tongzhou New Town, Shunyi New Town, Binhai New Area and Caofeidian, and an economic development area. This is also referred to as a "2+8+4 city cluster."
The Beijing-Tianjin-Hehei metropolitan region, with a population of 8.5 million, covers 183,400 square kilometers.
The joint development plan aims to make the following cities complementary to each other:
Beijing is the capital of China with a population of 21 million. It is also the country's political,cultural and international exchanges center.
Tianjin borders Hebei Province and Beijing Municipality, and lies about 26 nautical miles inland from the Bohai Gulf off the Yellow Sea on China's east coast, and it is the largest open city on the coastline in northern China.
Shijiazhuang is the capital of China's Hebei province. It is about 280 kilometers (170 miles) southwest of Beijing.The city is the largest base for the pharmaceutical industry and is also one of the most important textile industry bases.

The city of Langfang is located in the east-central part of Hebei province, midway between Beijing and Tianjin, and it is thus sometimes referred to as a "corridor connecting Beijing and Tianjin".The city aims to improve its service sector so as to serve as an eco-tourism destination for visitors from the capital.
Tangshan is an industrial city of 7 million people in Hebei province. It is considered to be Hebei's economic center and boasts sufficient natural resources of coal, iron, petroleum and natural gas to meet the requirements of the Beijing-Tianjin-Hebei megalopolis.

Cangzhou, a coastal city in Hebei province, faces the Bohai Sea to the east, borders Baoding City to the west and Shandong Province to the south - and it is near Beijing and Tianjin to the north. In 1988, Cangzhou was approved by the State Council as one of the county's open coastal cities, and it is known for its efficient transportation network.
Chengde is located in the northeastern part of Hebei province, with a population of around 3.7 million. It borders Liaoning province to the east and the Inner Mongolia Autonomous Region to the north. It is near Zhangjiakou City to the west and Beijing to the southwest.
