“…The inequalities in high-quality health service supply, especially in PHC, remained a serious challenge to China's healthcare system, as well as the whole world (Gao et al, 2002;Wang, Wang, and Maitland, 2012;Chen et al, 2019). In China, the gap between supply and demand, urban and rural areas, the Eastern area and the Western area, and the health institutions in the grass-roots level and tertiary hospitals in health service has always been the great obstacles to promoting and protecting the health of the whole nation (Wang, Wang, and Maitland, 2012;Wu et al, 2017;Yang, Wang, and Xue, 2019). The utilization of PHC in China is low (Zou et al, 2015), and patients prefer to tertiary comprehensive hospitals for high-quality health service and medical technology (Jiang et al, 2015), which causes the misuse of the medical resources, higher medical costs under the medical reimbursement policy, and the overload in the tertiary comprehensive hospitals leading to more medical conflicts and lower satisfaction.…”
