OMG. Is that an athlete tracks? In asian countries that usually means that is a school there. I can also see basketball courts and tennis courts too. If there is a school there that means there are children there. Are therer going to be shops too? Which begs the question, can the island have viable civilian population (and economy)?
It certainly seems to be an athletic track...and I know they were building a school.
Having set it up as a prefecture...there will definitely be a growing civilian population IMHO, including their families.
The latest I heard was that there are 1,500 civilians on the island already, and 6,000 military personnel.
If you don't mind the analogy it reminds me a bit of GTMO. sure, all we hear about is the detainees.
However its a complete Naval and Marine base. That includes civilians. If memory serves GTMO has a McDonald's, a Basken Robins, Starbucks coffee shop, KFC, Subway Restaurant, Taco Bell, A&W hamburger (heck I live in a civilian city in the US and I cant say I can go to half of this list already!) and a Beyer Ice cream.
All of this list is unique to GTMO as the only locations in all of Cuba.
That said although they are franchises. The base economy much as I suspect the island base to be is limited and not del sufficient or a growth industry. All the Franchises are operated by the USN for the purpose of moral of the base personal and family's the proceeds are mostly targeted to base moral.
On base is a theatre and 3 schools a Day care, a Elementary school and a High school operated by the DoD.
I would imagine that the PLA would fallow a similar plan for basing of personal on larger islands, smaller Island bases or artificial habits might be operated more like large naval ships with only duty personal on board in a rotation of a blue and gold team (or what ever you want to call it.) a crew operating for a set period maybe a few months then rotating back to a larger home base well a relief crew takes over.
Think of it like a Company town model. You work for the company but because of the remoteness the company has to take measures to keep you happy and healthy bot physically and mentally and since you are a long term employee and are likely to be posted there a long time, they offer you housing for you but not just you your family as well. But if they let you take your family they have to keep your family functioning so they give you schools and youth centers for your kids and if they do that well they might as well take other steps like comfort foods as going to the same Cafeteria is pretty boring and really would you drag your kids there?
So they open a cantina that sells groceries and restaurants and shopping for clothes and shoes, maybe a car lot but definitely bus and public transportation so people can get around with ease. It seems idyllic but there are limitations, if you retire or quit you pretty much have to move out. Its a closed economy growth is based more on recognized needs from inside the chain of command. Where in a traditional economy people can come in at random and build a small business or go out of business or people can come in and change jobs or other things in the company town model everything is operated as a single unit. And if the Company goes under or decided to move on then the whole town would be abandoned and turned into a true Ghost Town".
