paragraph_text: Sector composition
  
  The city has a post-industrial economy that is dominated by the tertiary sector (services), which generated 83.8% of output, followed by the secondary sector (manufacturing, construction) at 15.8% and the primary sector (agriculture, mining) at 0.26%. The services sector is broadly diversified with professional services, wholesale and retail, information technology, commercial real estate, scientific research, and residential real estate each contributing at least 6% to the city's economy in 2022.
  
  The single largest sub-sector remains industry, whose share of overall output has shrunk to 12.1% in 2022. The mix of industrial output has changed significantly since 2010 when the city announced that 140 highly-polluting, energy and water resource intensive enterprises would be relocated from the city in five years. The relocation of Capital Steel to neighboring Hebei province had begun in 2005. In 2013, output of automobiles, aerospace products, semiconductors, pharmaceuticals, and food processing all increased.
  
  In the farmland around Beijing, vegetables and fruits have displaced grain as the primary crops under cultivation. In 2013, the tonnage of vegetable, edible fungus and fruit harvested was over three times that of grain. In 2013, overall acreage under cultivation shrank along with most categories of produce as more land was reforested for environmental reasons.
