Abstract
This study was carried out with the intention of obtaining and providing knowledge in developing
policy to promote the growth of private hospitals with least negative effect on government health care. By
studying the literature about private hospital segments and the impact of government policy together
with questionnaires sent to most private hospitals in Thailand about their resources and services back to
five years previoustly, the financial resources of the hospitals were analyzed using the data from the Ministry
of Commerce and the Stock Exchange of Thailand. Quantitative data obtained by interviews were
also analyzed. From these processes, we found that the rapid growth of private hospitals during the past
three decades has a strong relationship with the economic status of the country. The Government’s investment
promotion policy has had both negative and positive impacts on the income of hospitals. Largescale
hospitals earn more income than small-scale hospitals. Hospitals in Bangkok earn more income than
hospitals in rural areas. Three factors, namely price, quantity and quality, together with quality assurance
by the Ministry of Public Health, the National Health Security Office and the Social Security Office
synergized the working process to reform the health infrastructure of Thailand.
