There is no objective way to measure something that is subjective. Any growth caused by inflation are false growth.
Two mistakes in your reasoning:
1. It is the other way around; when an economy has by itself a business opportunity to grow, but the money supply doesn't get increased accordingly, this growth will be at least partially hampered.
2. If the prices don't grow, there is no inflation. Please read any definition of inflation you can find apart from the first post in this thread.
