London’s economy is both very specialised - in highly productive, export-oriented service sectors such as finance and insurance and advanced professional services – but also big enough to accommodate large numbers of jobs in most of the key employment sectors. Exports from the specialised sectors are a key driver of London’s trade surplus with the rest of the world. At the same time, London attracts inward investment from abroad. Between 2003 and 2015, London secured 39 per cent of all foreign direct investment (FDI) projects in the UK and 26 per cent of all FDI project-related jobs in the UK. London is home to a thriving knowledge economy, with international strengths in life sciences, tech and digital, culture and creative industries, advanced urban services and low carbon and environmental goods and services.
