The manufacturing sector was the largest (54.8%) and fastest-growing (18.2%) sector of Tianjin's economy in 2009; farmland takes up about 40% of total land area. Tianjin Municipality also has about 1 billion ton of petroleum deposits, with Dagang district (in Binhai New Area) containing important oilfields. EADS Airbus is an important manufacturer, and has opened an assembly plant for its Airbus A320 series airliners, operational since 2009. Tianjin also hit the news in 2010, as the current fastest supercomputer in the world, Tianhe-1A, is located at the National Supercomputing Center in Tianjin. GDP in 2009 hit RMB750.1 billion, with a per capita of RMB62,403.
The municipality recorded an impressive 16.5% increase in GDP in 2009, second only to the 16.9% rate in resource-rich Inner Mongolia, and nearly double the national growth rate. In the short term, infrastructure spending will buoy Tianjin's economy. There are substantial projects under way to extend the metro system (which currently has only one line) and improve road and rail links with the nearby national capital, Beijing.
