2.2 Planet Specialization Mechanics

[FiddleSticks96]

As we all know, 2.2 has further incentivized planet specialization by added a planet wide bonus (+5% for most types) to worlds that focus on a particular basic resource or on research; however, I have yet to figure out exactly what the conditions are for each of these specializations. I have seen these bonuses and have even acquired them myself and I know generally what I must do to get them (i.e. build mining districts until the planet becomes a "mining world"). I don't know the specifics though and my current game is certainly confusing me. One of my worlds has 7 mining districts, 3 agri districts, 1 energy district, and 3 city districts. I would have thought this would be a mining world by now but it is still considered a rural world (+2% worker output).

What I want to know is if anyone here has figured out the exact conditions we must meet to get these bonuses?

Each district and building as a weight attached to them that determines what the specialisation is. Going off the wiki information, each non city district applies a bonus of 1 to it's pure bonus specialisation weight (and the production buildings add additional weight), but add 0.75 to the rural world weight. So in your case you have a weight of 7 for mining, but (0.75*11) for rural world, so you get a rural world. If you really want it to be a mining world, build the mineral processing buildings and more mining districts. Specifically, for four non mining, non city districts, you need 9 mining districts and a mineral processing plant to make it a mining world. In general, you need more then twice the number of other districts, plus the specialisation building.
