How much will gdp be boosted by investing 1 100 million yuan in infrastructure?

First of all, it depends on where the money comes from. If it is the surplus of taxes or government profits in previous periods, it will directly bring about 100 million GDP. Then it will indirectly affect consumption and investment. The specific impact depends on the impact index. The comprehensive impact is generally between1.500 million and 350 million.

But if the money depends on the current tax or government budget, it will have a negative impact on current consumption and investment. Specifically, it may even be lower than 1 100 million.
