this has been a long time coming, iirc.
the ghost cities were just inflating everything to make it all look good.
The ghost cities seem to be another problem. Apparently they are not that big of an issue as people think they are. Mainly they are built in preparation for migration of people from the country to the city. So instead of suburbs they build ghost towns which are filled up in a couple years. Not immediately but in like 5 to 6 years.
Example certain parts of Shanghai were once ghost cities.
LinkQuote from the article:
"But while building the core areas of new cities is something that China does with incredible haste, actually populating them is a lengthy endeavor"
Apparently once vital utilities and infrastructure like transit are put in place does the growth begins. So apparently calling them ghost cities seem to be a bit of a premature argument.
