Jing-Jin-Ji is the name given to the integrated megaregion of China that includes the capital Beijing (Jing), neighboring Tianjin (Jin) and surrounding Hebei Province (also officially known by the historical one-character name Ji). Coordinating the development of the three regions became a national-level strategy in 2014, with the aim of relieving Beijing of functions non-essential to its role as China's capital, maintaining regional economic growth, improving infrastructure connectivity, and promoting ecological conservation and the sharing of public services.
Over the past decade, Beijing, Tianjin and Hebei have, by breaking down administrative barriers and promoting policy coordination, achieved a leap in economic size and intensified industrial collaboration. The region's GDP grew from around 5.5 trillion yuan ($809 billion) in 2013 to nearly 12 trillion yuan ($1.76 trillion) in 2025. Its industrial structure has been continuously optimized, with the service industry accounting for over 70 percent and a collaborative model of "research and development in Beijing and commercial use in Tianjin and Hebei" becoming established.
Located in Hebei, Xiongan New Area is the primary destination for relocating functions previously undertaken by Beijing that are not related to its role as the capital. It is also often dubbed China's "city of the future." The Beijing Daxing International Airport, which opened in 2019 in Beijing's southern suburbs, has also been a driver of regional development.
The three places have also jointly pursued major ecological projects including sandstorm, soil erosion and river basin pollution control. The Beijing-Tianjin sandstorm source control project has completed afforestation of more than 667,000 hectares, and the average concentration of PM2.5, fine particles with a diameter of 2.5 micrometers or smaller, a key indicator of air pollution, in the region has decreased over 70 percent since 2013.
As urbanization increases the size of China's cities, the country is increasingly turning to regional integration as a means to relieve pressures on urban infrastructure and ensure people's wellbeing continues to improve. Jing-Jin-Ji is at the forefront of this approach.
