Jingjinji Metropolitan Region or Jing-Jin-Ji (JJJ)[a], also known as Beijing-Tianjin-Hebei, is the national capital region of China. It is the biggest urbanised region in Northern China that includes an economic region surrounding Beijing, Tianjin, and Hebei, along the coast of the Bohai Sea.[1] 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 2016, Jingjinji produced 10%(US$1.1 trillion) of China's Nominal GDP. [2] Jingjinji has traditionally been involved in heavy industries and manufacturing. Tianjin's strengths have always been in aviation, logistics and shipping. Beijing complements this 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, also attracting foreign investments in manufacturing and health services.[3][4]

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.[5]

In recent decades, petroleum and natural gas deposits have been discovered in Jingjinji coast Bo Hai.
