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.
