This is because as incorporated non-profit organizations, Taiwan's private hospitals are required to reinvest their profits in health care services and research, and cannot distribute them to shareholders. However, China currently has no laws governing non-profit corporations, and only government-subsidized public-sector hospitals that care for the health of the general public are recognized as non-profit organizations.
原因在於，台灣的私立醫院屬於財團法人，不以營利為目的，也就是說，醫院的利潤不能分配給股東，必須再用於醫療服務與研究上，但中國目前沒有財團法人的法令，只有接受政府補貼、照顧老百姓的公立醫院才屬於非營利機構。
