Abstract: Conventional concept and connotation of primary health care are no longer being well adapted to the development of human society, economy and health. After reviewing the development of conventional concept of primary health care, we analyze the concept′s characteristics that do not adapt to social development. Based on the conventional concept, the future - oriented connotation of primary health care is to provide community - based, integrated and people - oriented services which rely on technology, social innovation and multi - sectoral collaboration, and with the capacity to respond to health emergencies and climate and environmental change. The new connotation of primary health care would possess following six features: providing community - based service, with integrative and continuous framework, incorporating technological and social innovation, participating in emergency management, being capable of participating in response to climate and environmental change, and with policy environmental support.
