 The development process of Vietnam becomes more and more complicated and more and more comprehensive so we need a comprehensive point of view on every specific area that we want to address. In support of the Sustainable Development Goals, the United Nations has called for a data revolution. Vietnam, together with UNU-Wider and its partners, have established data sets charting the country's rapid development. This series shares some of the lessons learned. After we have data, before that, researchers in Vietnam could hardly have data reliable or better evidence-based for our researches. But when we have researches like this, we could have better evidence-based for our acumen of our recommendations for policies in Vietnam. If we want to recommend something or to comment even on some development in Vietnam, we need the evidence-based for that. We need better acumen. I would suggest that we have more consultation or reading more or other researches in Vietnam in order to make comparison between them and continue to focus on the key areas that the researches so far focus in because these are really the differentiation between our researches and other researches. We have a very strong point in this, but we need also to consult others to have a more comprehensive picture on Vietnam. Researches are important for policy makers and policy makers can use these researches as very important base or evidence base for them in order to introduce better policies. It's not necessarily that researchers always work based on the need of policy makers. I would prefer researchers based on the need of the society of the development process in order to help policy makers to understand better on the need of development.
