China's innovation and research contribution to combating neglected diseases: a secondary analysis of China's public research data.

Background: Many emerging and developing economies, such as China, have played the important roles in combating global neglected diseases (NDs). This study aims to explore China's public landscape of research projects and funding of NDs and to provide empirical evidence on promoting China's participation in addressing global health priorities that disproportionately affect developing countries.

Methods: We systematically sourced China's public funding information from the National Natural Science Foundation of China and provincial science and technology agency websites up to August 16, 2019. Following the G-FINDER R&D scope, we screened projects of NDs for analysis. National-funded projects were reviewed on an annual basis for exploring the trends and distribution of funding flows. Information on provincial-funded projects was compared with national projects by disease, research type, and geographical distribution.

Results: A total of 1266 projects were included for analysis and categorized by year, funding source, recipient, disease, research type, region, and province. China's national public funding for ND research reached a historical peak of USD 16.22 million in 2018. But the proportion of ND research to all public-funded projects was less than 0.5%, and over half of the ND projects were allocated to "the big three," i.e., tuberculosis, HIV/AIDS, and malaria. About 58% of national and provincial ND projects focus on basic research. Economically developed regions and municipalities play dominant roles in leading national ND research, such as Beijing, Shanghai, and Guangdong. Provincial ND projects are primarily driven by endemic regions.

Conclusions: As a new emerging high-tech innovator, China has gradually increased public input to ND-related innovation and research. But there is still a large funding gap among NDs that requires China's increased support and participation. National development plans and cooperative health needs should be taken into account for China's participation in promoting global research and development (R&D) for combating NDs.
