Answer could be

2

As,

the sum of all the numbers of small squares should equate to sum of numbers formed by the bigger suqares (from Right bottom to Top left)

That is for example:

? = ? (square of size 1 X 1) 0 + 1 + 4 + 7 + 6 = 3 + 5 + 8 + ? (of size 2 X 2) - thereby giving ?=2 and similarly for size 4 X 4.
