NEW DELHI: Finance Minister Arun Jaitley has allocated Rs 3,96,000 crore to the entire infrastructure sector, up from the total allocation for the sector in the last budget at Rs 2,21,246 crore.Public sector spending is expected to be the prime driver for infrastructure build-out over the next year as private sector investment remains subdued.The infrastructure sector of the Indian economy still continues to be one of the main drivers of the economy.While more infrastructure spending will lead to more jobs, it can also result in a crowding-in impact, leading to more jobs and investment in the private sector too.
