When India gained independence in 1947, the public sector was established to play a key role in economic development due to the poor economic conditions and lack of private sector enterprises. The early five-year plans focused on developing core sectors through public enterprises. However, in the 1990s, economic liberalization led to a reevaluation of the public sector role and increased privatization and competition with private enterprises. While public sector enterprises helped develop infrastructure and promote regional growth in the early years, issues later emerged like lack of competition, inefficient management, and overcapitalization of projects, leading to reforms to improve efficiency of the public sector.
