"For meeting the deficit target of 4.1 per cent, instead of disinvestment of PSUs, other ways should be examined by way of improving the productivity and overall governance," SCOPE Director General U D Choubey said.
Disinvestment proceeds are vital to the exchequer to lower the fiscal deficit.
Finance Minister Arun Jaitley yesterday raised the disinvestment target for the current fiscal to Rs 58,425 crore.
The target includes Rs 43,425 crore through stake sale in PSUs and another Rs 15,000 crore from sale of residual stake in the erstwhile government companies, as per the Budget document.
