中心にする vs. 中心とする

Question

I am currently studying Japanese and one of the recent grammar points I ran into is the construct「〜を中心［に・と］する」.

I was wondering whether the choice of particle has any particular connotation, or whether there is any sort of rule for deciding which one to use.

Answer 1

• Aに： A ←
• Aと： " A "

So, ～を中心に feels like you are setting something at the center by moving yourself like when you are targeting the object, while ～を中心とする feels like you just regard something that is already fixed there as the center.
