Following the introduction of the reform and opening-up drive in 1978, to address problems such as a severe shortage of medical and health resources and a lack of service capability and low efficiency, the government allowed multichannel financing for the medical industry, and encouraged medical development in various forms, by increasing resource supply, opening up the pharmaceuticals manufacturing and circulation market, developing the pharmaceutical industry, and promoting TCM. Economic incentives were adopted to encourage medical personnel to enhance their performance. At the First National Health Service Meeting in 1996, a decision was made on implementing the guiding principles for health services in the new era, namely, "focusing on the rural areas, prioritizing prevention, equal emphasis on Western medicine and TCM, relying on science and education, encouraging public participation, promoting public health, and serving socialist modernization." In 1998, China began to form a social medical insurance system to cover the basic medical needs of workers. In 2000, it set the goal of establishing an urban medical and healthcare system in line with the socialist market economy, so that the people could enjoy reasonably priced, high-quality medical services, and thus become healthier. In 2002, the government released the Decision on Further Enhancing Health Services in Rural Areas. Taking into consideration the levels of economic and social development in rural areas, the government decided to drive health services reform to a deeper level, and put in more funding to rural areas, to provide different levels of medical services to rural residents.
