1) The speed/pace of modernization have to be in sync/have to be parallel to the development mindset .
2) The speed/pace of modernization is not even with the development of mindset.
I hope somebody can tell me if I have constructed the above sentences correctly. Thanks.
It's not clear what you mean by "development mindset" and "development of mindset".
However, here are some possibilities.
"The pace of modernization has to be in sync with the development of an appropriate mindset", or "…of the right mindset", "…of a good mindset".
