The purpose of this study is to analyze the details and investment scale of regional development projects carried out by public institutions relocating in innovative cities to identify regional characteristics and the cause of regional gaps. To this end, the characteristics of regional development projects were analyzed targeting 63 public institutions that moved to 10 innovative cities nationwide. As a result of the analysis, first, the total investment in regional development projects was cut in the order of public enterprises, quasi-governmental institutions, and other public institutions, and statistically, there were differences between groups. Second, the size of investment in the field of regional industrial development was highly correlated with the sales variable among the size characteristics of public institutions, and the priority purchase of local goods had the highest correlation with the number of employees in all three types of public institutions. In particular, it was analyzed that local talent development projects and resident support projects showed a low correlation with institutional size variables in all types of public institutions. This suggests that the system needs to be improved so that public institutions with larger assets and higher sales can promote investment in the field. Finally, it was analyzed that public institutions that are highly related to regional specialized industries have invested more than local industries and human resources development. This could lead to policy implications that the connection between the work of public institutions and local industries should be considered first when additional public institutions are relocated in the future, and that local government-level industrial promotion policies should be carried out to strengthen the connection between public institutions and regional specialized industries that have completed the relocation.
