what is the effects of Chinese products on small

I want to know if the small business has been effected by the increase of Chinese products in the U.S. I want to know if it has effected it in a Positive way or in a negative way. I also would like know if the U.S. has experienced any Job loss by the rise of chines imports to the U.S.
I would be thank full if any one can help.

Thank you
Sam
