Jing-Jin-Ji

In 2019, Jingjinji produced around 8% (US$1.2 trillion or US$2.4 trillion in PPP) of China's GDP or about the same size as Mexico,[4] occupying an area about twice the size of South Korea.[5] Jingjinji has 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, also attracting foreign investments in manufacturing and health services.[6][7]

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.[8] 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 that are to be completed by 2020.[5] The long-term goal is to create a one-hour commuting region; an additional 24 intercity railways are planned to be built before 2050.[9]

In recent decades, petroleum and natural gas deposits have been discovered in the Jingjinji region's coast of the Bohai sea.
