[Pokemon] What kind of government does the world of Pokemon have?

And does it differ by region?

I always thought that the government of pokemon was based off the strongest trainers in each region. The gyms are local authority, the elite 4 overrule the gyms, and the champion acts as the dictator of everything. 

This explains why towns with gyms seem to look towards the gym leader as the local authority, and why trainers attempt to reach the elite 4 and become the champion themselves.
