It is possible to design a strategy for expanding the applications of GIS by identifying why social science researchers use GIS. This study analyses motivating factors for the researchers to utilize GIS and their satisfying factors towards the result. It is based on survey results which was answered by social science researchers at national research institutes and local governmental research institutes in South Korea in the perspective of merits of applying GIS, level of GIS usability and experienced effectiveness of applying GIS. Analysis result reveals that motivating factors to researchers applying GIS are correlated with efficiency in their research and satisfying factors are correlated to the usability. Then, we induced a fact that motivative factors for applying GIS is not related to the satisfaction of that. It may be a reason which researchers use GIS less applying in social science fields. As a result, it is necessary to connect the motivating and satisfying factors to further expand GIS applications.
