So are the flights between mainland China and Taiwan then filled with people from then mainland who are visiting Taiwan and not the reverse?
The ROC and PRC issue documents (the Entry & Exit Permit and the Mainland Travel Permit, respectively) to citizens of the opposite government that serve as passports in cross-strait situations. These are for entry and exit, though; I don't think they're required for transit within 24 hours.
