The Jing-Jin-Ji cluster is an expanded urban agglomeration consisting of Beijing (Jing), Tianjin (Jin), and Hebei (Ji). It is the biggest urban agglomeration region in North China, including an economic region surrounding the municipalities of Beijing and Tianjin, and along the coast of the Bohai Sea. This emerging region is rising as a northern metropolitan region rivaling the Pearl River Delta in the south and the Yangtze River Delta in the east. In 2020, it had a total population of 110 million people, comparable to that of the Philippines.

## Economy

| | Area (km$^2$) | Population (2020) | GDP (CN¥) | GDP (US$) |
| Beijing (Jing) | 16,411 | 21,893,095 | CN¥ 4,735 billion | US$ 672 billion |
| Tianjin (Jin) | 11,946 | 13,866,009 | CN¥ 1,721 billion | US$ 244 billion |
| Hebei (Ji) | 188,800 | 74,610,235 | CN¥ 4,566 billion | US$ 648 billion |
| Jingjinji Urban Agglomeration | 217,156 | 110,369,339 | CN¥ 11.023 trillion | US$ 1.564 trillion |
As of 2024, the region's GDP is CN¥11.54 trillion (US$1.62 trillion), equivalent to that of Spain. It occupied an area about twice the size of the South Korea. Jingjinji had traditionally been involved in heavy industries and manufacturing. Tianjin's strengths have always been in aviation, logistics, and shipping. Beijing complements this economic activity with strong petrochemical, education, and R&D industries. The area is becoming a significant growth cluster for automobile, electronics, petrochemical sectors, automotive industry, software and aircraft, thus attracting foreign investments in manufacturing and health services.
The Chinese central government has made it a priority to integrate all the cities in the Bohai Bay rim and foster economic development. This includes building an advanced communications network, better highways, increased education, and scientific resources, as well as tapping natural resources off the Bohai rim. In 2016, the Central Government approved a US$36-billion plan to link the various cities making up this metropolis by rail in order to reduce commute times and to better integrate them. This plan includes the construction of nine railways that are 1,100 km (680 mi) in length, which are set to be completed by 2020. The long-term goal is to create a one-hour commuting region; an additional 24 intercity railways are planned to be built before 2050.
In recent decades, petroleum and natural gas deposits have been discovered in the Jingjinji region's coast of the Bohai sea.
