The primary health care system (PHCS) is the portal and basis for the national health
delivery system. There are a number of elements which comprise the PHCS, but the system
cannot be established and developed without the support of “three essential elements,”
including general practitioners (GPs), health insurance, and government health investment.
Through comparative analysis of the “three essential elements” of the PHCS between
California in the US and Guangdong in China, this article indicates that there are
three important aspects in developing a PHCS in China, as follows: training qualified
GPs; establishing a diversified health insurance system to strengthen the policy connections
between health insurance and the PHCS thereby increasing government health investment;
and broadening health financing channels.
