Corporate statism or state corporatism is a political culture and a form of corporatism whereby corporate groups form the basis of society and the state. By this principle, the state requires all citizens to belong to one of several officially designated interest groups (based generally on economic sector), which consequently have great control of their members. Such interest groups thus attain public status, and they or their representatives participate with national policymaking, at least formally.
Societies have existed historically which exemplified corporate statism, for instance as propounded by Othmar Spann in Austria and implemented by Benito Mussolini's regime in Italy (1922–1943), António de Oliveira Salazar's Estado Novo in Portugal (1933–1974) and by the interwar Federal State of Austria. After World War II, corporate statism influenced the rapid development of South Korea and Japan.
