When it came to strategic disinvestment, Bharat Petroleum Corporation Limited (BPCL) was theclear winner over its rival Hindustan Petroleum Corporation Limited (HPCL). The value of BPCL's shareholders' equity was risen by Rs. 33,000 crore as a consequence! In comparison to HPCL, which will remain a government-controlled corporation, the efficiency benefits at BPCL are expected to be more beneficial. So the chapter focuses on the efficiency benefits in India following privatisation. This paper covers the period from 1999-2000 to 2003-04, when 11 CPSEs underwent strategic disinvestment. Comparing these CPSEs to their counterparts in the same industry group requires the use of a difference-in-difference approach. Their recent privatisation has increased their net worth and profits, allowing them to compete on a level playing field with other enterprises. ROA and net profit margins, on the other hand, went from negative to positive, indicating that privatised CPSEs were able to generate greater wealth with the same resources as their rivals. If you take each CPSE one at a time, you'll receive better results, too. According to the research, privatisation has the potential to unleash the wealthcreating potential of CPSEs. As a result, the chapter favours a swift withdrawal of funds from the CPSE.
