Austria consistently ranks high in terms of GDP per capita, due to its highly industrialized economy, and well-developed social market economy. Until the 1980s, many of Austria's largest industry firms were nationalised; in recent years, however, privatisation has reduced state holdings to a level comparable to other European economies. Labour movements are particularly influential, exercising large influence on labour politics and decisions related to the expansion of the economy. Next to a highly developed industry, international tourism is the most important part of the economy of Austria.
