Background: Parkinson's disease (PD) is a common neurodegenerative disease, and obtaining accurate epidemiological data for this disease is very important for policy-making in public health. The purpose of this study was to determine the prevalence and incidence of PD in the People's Republic of China and explore possible future research directions. Methods: We systematically retrieved studies of the prevalence and incidence of PD in the People's Republic of China, Taiwan, and Hong Kong, and standardized the data according to the world's population in 2000. Results: Fifteen eligible studies were retrieved. Most were cross-sectional studies, and two thirds of the research was from the People's Republic of China. The prevalence of PD was reported in all the studies, but only two studies reported incidence data. The prevalence of PD in the People's Republic of China ranged from 16 to 440.3/100,000, and the annual incidence ranged from 1.5 to 8.7/100,000. Conclusion: The prevalence of PD in the People's Republic of China has been widely investigated in the studies published to date. However, due to methodological heterogeneity, the data reported by the different studies are not comparable. There is still a lack of information on the incidence of PD in the People's Republic of China. Therefore, future research is required to answer this question.
