Economy of Berlin
The economy of Berlin is dominated by the service sector, with around 84% of all companies doing business in services. Important economic sectors in Berlin include life sciences, transportation, information and communication technologies, media and music, advertising and design, biotechnology, environmental services, construction, e-commerce, retail, hotel business, and medical engineering. Berlin became one of the largest and most advanced industrial centers in Europe after 1870. After 1900 the Berlin banking district became a major continental financial center and was home to a number of prominent banks. After the end of World War II in 1945 and  the subsequent political divisions, the city's location inside of East Germany led to an exodus of many major firms to West Germany. Berlin's economy has been affected through the years by the city's changing geopolitical fortunes from 1961-1989. The city stagnated economically during the Cold War, when West Berlin was isolated geographically and East Berlin suffered from poor economic decisions made by East Germany’s socialist central planners. Furthermore, few East German companies survived the collapse of the GDR and the attempt to privatize them through the Treuhandanstalt. After German reunification in 1990 large service, technology  and creative sectors re-established in the city. A number of companies have re-opened secondary corporate headquarters or satellite offices in Berlin. A number of major German companies were founded in Berlin, such as Siemens, Deutsche Bank, Lufthansa, Allianz, AEG, Telefunken, Osram, Knorr-Bremse and Edeka. History. Berlin was founded at a point where trade routes crossed the river Spree and it quickly became a commercial center. During the early modern period, the city prospered from its role as Prussian capital by manufacturing luxury goods for the Prussian court and supplies for the Prussian military. Industrial Revolution. During the  mid-19th century, the Industrial Revolution transformed the city’s economy. Berlin became Germany’s main rail hub and a center of locomotive manufacturing. The city became a leader in the manufacture of other kinds of machinery as well, and developed an important chemical industry sector. Toward the end of the 19th century, Berlin became a world leader in the then cutting-edge sector of electrical equipment manufacturing. As the "de facto" center of the German Zollverein, or Customs Union, and later the seat of the Reichsbank, Berlin became Germany’s banking and financial center as well. Berlin suffered from both  the German hyperinflation of the 1920s and the Great Depression of the 1930s. The city’s economy revived as a center of weapons production under the Nazis, but it lost a pool of entrepreneurial talent when the Nazis forced Jewish businessmen to sell their holdings and ultimately massacred most who did not flee Germany. After the World Wars. World War II severely damaged Berlin’s industrial infrastructure, and Soviet expropriation of machinery and other capital equipment as “war reparations” further damaged Berlin’s industrial base. Soviet restrictions on transport impeded communication with West Germany and ended hopes that Berlin would  resume a role as Germany’s financial center; most banks established headquarters in Frankfurt. In East Berlin, socialist central planners rebuilt a manufacturing sector, but one that was not competitive internationally or responsive to market demand. West Berlin’s economy grew increasingly dependent on state subsidies and on its role as an educational and research center. Reunification. Berlin’s and Germany’s unification brought the collapse of many of East Berlin’s producers, which could not compete with market-disciplined Western competitors. Massive unemployment was only partly compensated by the growth of jobs in the construction and infrastructural sectors involved  in rebuilding and upgrading East Berlin’s infrastructure. The move of the federal government from Bonn to Berlin in 1999 brought some economic stimulus and tens of thousands of jobs from government employees, parliamentary services, lobbyists and journalism to Berlin. Berlin’s service sectors have also benefited from improved transportation and communications links to the surrounding region. While some manufacturing remains in the city (Siemens and Bayer Schering Pharma have headquarters in Berlin), the service sectors have become the city’s economic mainstay. Research and development have gained significance, and Berlin was ranked among the top three innovative regions in  the EU (after Baden-Württemberg and the Île-de-France in 2006. In the same year unemployment remained high, at 16.5% as of 2006. Fast-growing sectors are communications, life sciences, mobility and services with information and communication technologies, media and music, advertising and design, biotechnology and environmental services, transportation and medical engineering. Since 2015 Berlin is the top congress city in the world and is home to one of Europe's biggest convention centers in the form of the CityCube Berlin (formerly Internationales Congress Centrum). It contributes to the increasing tourism sector encompassing 592 hotels with 90,700 beds (2007  figures) and numbered over 22 million overnight stays by 9.8 million tourists in 2011. Berlin has established itself as the third most visited city destination in the European Union. Berlin's economy has grown continuously above the German average in the period from 2005 to 2013. This trend is set to continue, with important improvements to infrastructure, such as the biggest European crossing station, Berlin Hauptbahnhof (inaugurated 2006), the opening of the 3rd biggest German airport, Berlin Brandenburg Airport, in 2020 replacing the decrepit Tegel Airport which was not fit to serve as a modern airline hub. Also, the revered  Berlin music scene, attracting tens of thousands of young tourists flying in for the city's famed clubs has become an increasingly important part of the economy and is set to gain the support of the city music board modeled after the German film promotion authority.
