First,the following are definitions of big and large I found in Macmillan Dictionary.
definition of big:
1.large in size
2.large in degree, or having a strong effect
definition of large:
1.bigger than usual in size
2.bigger than usual in number or amount
Then I use TOTALrecall to find the differences between big and large through sentences.
Here I list several sentences from TOTALrecall.

I also try WEBCALL, I found the top 5 of "large" which are frequently used,they are:
number 12617
amount 4316
part 3514
city 2912
scale 2135
Afeter reading information above,we can see that "large" is usually used by describing one object's size or describing one thing in number or amount.
I think this statement can be proofed by the evidence from WEBCALL.
I think this statement can be proofed by the evidence from WEBCALL.
And "big" not only be used by describing object's size but also describing how important the thing can be.
e.g. I had never been involved in making the big decisions before.
e.g. I had never been involved in making the big decisions before.
Also,"big" can sometimes be used in describing that one thing has a strong effect.
e.g.The concerts have been a big success.
Combine the comparison above,I can conclude that
Large: Descibe the practical thing's size in amount or number.
Big: In addition to describing practical thing's size,it can also describes other meanings about the impractical things.
