Facing the aggravating trend of an aging population and a fragmented medical service delivery system, the Chinese Central Government has introduced a series of policies to promote the development of integrated care against the background of the “Healthy China Strategy”. The achievement of integrated care depends on the choice of policy instruments. However, few studies have focused on how policy instruments promote the practice of integrated care in China. This article aims to obtain a deeper understanding of the use of policy instruments in the development of integrated care in China. Policy documents are the carriers of policy instruments. National-level integrated care policy documents from 2009 to 2019 were selected. Using the qualitative document analysis method, this paper conducts an analysis of integrated care policy instruments. In order to comprehensively view the integrated care policy instruments, a three-dimensional analytical framework consisting of the policy instruments dimension, stakeholders dimension, and health service supply chains dimension is proposed. The results are as follows. (1) From the perspective of policy instruments, the integrated care policy has adopted supply-side policy instruments, demand-side policy instruments, and environmental policy instruments. Among the three types of policy instruments, environmental policy instruments are used most frequently, supply-side policies are preferred, while demand-side policy instruments are relatively inadequate. (2) As for the stakeholders dimension, the central policy instruments focus on the health service providers, while less attention is paid to the health service demanders. (3) In terms of health service supply chains, the number of policy instruments used in the prevention stage is the highest, followed by the treatment stage, whereas less attention paid to the rehabilitation stage. Finally, suggestions were made for the development of integrated care by better perfecting policy instruments.
