The Navratna Policy was introduced by the Government of India to provide greater financial and operational autonomy to leading PSUs.
Justifications:
1. Increased Operational Freedom:
- The Navratna status allows PSUs greater decision-making power, helping them compete with private enterprises both domestically and globally.
2. Facilitating Disinvestment and Efficiency:
- The policy has encouraged disinvestment, allowing partial privatization, thereby reducing the financial burden on the government.
- It has helped PSUs become self-reliant and more competitive in the global market.
Conclusion: The Navratna policy has played a crucial role in strengthening India’s public sector enterprises, allowing them greater autonomy while encouraging efficiency and privatization.
