Generate practical evidence

As a research organization, we generate practical evidence.

1. Based on the issues raised from technical cooperation activities and policy analysis, we identify research topics and formulate research teams to conduct the study.
2. We identify the stakeholders who would utilize the research findings and coordinate with them from the planning stage.
3. We participate in a variety of academic and research meetings to improve our research capabilities.
4. We work together with other departments within NCGM or with domestic or international organizations to disseminate research findings.
