Institutional development of legislative supporting agencies (LSAs) from a perspective of difference between presidential and parliamentary systems

This article focuses on legislative supporting agencies (LSAs) as agencies supporting the activities of legislature and elucidates the relation between LSAs’ institutional development and other political factors, paying attention to the difference between the presidential system and the parliamentary system. The concrete factors that would influence LSAs’ development, i.e. ‘presidential system or parliamentary system’, ‘whether a government has a right to initiate a bill’ and ‘whether a person can concurrently have positions in both the executive and the legislative branches’, are presented, and as a result of statistical analyses, it is clarified that these factors have an impact on the development level of LSAs to some extent.
