As of 2025, the region's
GDP is
CN¥12 trillion (
US$1.7 trillion), slightly larger than
Turkey. It occupied an area about twice the size of
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 in length, which are set to be completed by 2020. In recent decades,
petroleum and
natural gas deposits have been discovered in the Jingjinji region's coast of the Bohai sea.
Metropolitan areas In 2013-2014,
General Secretary of the Chinese Communist Party Xi Jinping gave directives on
coordinating development in the region, elevating development strategies in the region to be a national priority. In particular, planning strategies sought to alleviate development pressure in Beijing. The desire to alleviate the development pressure of Beijing's increasing non-capital functions was formalized in the June 2015
Outline Plan for Coordinated Development of Beijing-Tianjin-Hebei and subsequently resulted in the establishment of
Xiong'an. Xiong'an is where Beijing's non-capital functions, such as universities, research institutes, and high-tech innovation centers are planned to be transferred over time. ==Major cities==
