다국어 초록 (Multilingual Abstract)

The purpose of this study is to compare the political effects of the mixed electoral systems in New Zealand, Japan, and S. Korea. These countries have changed to mixed electoral systems to accomplish the votes-seats proportionality and the stability of party politics since 1990`s. This study used the indices such as ``electoral disproportionality``, ``effective number of parties``, and ``electoral volatility`` to analyses the political effects of electoral reform. The results of the analysis are as follows: The mixed member proportional system (MMP) of the New Zealand has made the positive political effects on the votes-seats proportionality and the stability of party system. However, the mixed member majority system (MMM) of Japan and Korea has not made the satisfactory political consequences on the electoral disproportionality and the electoral volatility in general elections. In other words, these countries have been increasing the electoral disproportionality and the instability of party system. Particularly, the party politics have been continuing that electoral competition depended on the stronger person and region than the political ideology and public policy. To conclude, this study argues that the mixed member proportional system is stronger effects on the increasing electoral proportionality and the stability of party politics than the mixed member majority system.
