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