The Paris Region is France’s premier centre of economic activity, and with a GDP of €607 billion (US$845 billion), it is not only the wealthiest area of France, but has one of the highest GDPs in the world, after Tokyo, New York, Los Angeles, Seoul and London making it an engine of the global economy. Were it a country, it would rank as the seventeenth-largest economy in the world, larger than the Turkish and Dutch economies and almost as large as Indonesia’s. While its population accounts for 18.8 percent of the total population of metropolitan France, its GDP accounts for 31.0 per cent of metropolitan France’s GDP. Wealth is heavily concentrated in the western suburbs of Paris, notably Neuilly-sur-Seine, one of the wealthiest areas of France. This mirrors a sharp political divide, with political conservatism being much more common towards the western edge, whilst the political spectrum lies more to the left in the east. The Parisian economy has been gradually shifting towards high-value-added service industries (finance, IT services, etc.) and high-tech manufacturing (electronics, optics, aerospace, etc.). However, in the European Green City Index, Paris was still listed as the second most”green” large city in Europe, after Berlin. While the Paris economy is largely dominated by services, it remains an important manufacturing powerhouse of Europe, especially in industrial sectors such as automobiles, aeronautics, and electronics. The Paris Region hosts the headquarters of 30 of the Fortune Global 500 companies.
