His 32-year term as General Secretary covered most of the period the People's Republic of Hungary existed. Due to Kádár's age, declining health and declining political mastery, he retired as General Secretary of the party in 1988 and a younger generation consisting mostly of reformers took over.

Formerly the Central Committee of the MSZMP announced János Kádár’s plans for the reform of the economy, known as the New Economic Mechanism (NEM). The reform is considered as "the most radical postwar change" of any Comecon country. The plan, which became official 1 January 1968, was a major shift to decentralization in an attempt to overcome the inefficiencies of central planning. The NEM represented a move away from the Joseph Stalin economic system of compulsory plan indicators in favor of a policy that states profits as the enterprises main goal. The new economic policy was a "comprehensive reform of the economic system", creating market relationships among firms, using prices as allocative functions and firms responding to prices to maximize profits, and using profits to budget new investments.
