일본 정당의 석패율제도 활용 전략 분석을 통한 한국에의 시사점

Abstract

This article analyzes the Japanese parties' strategic use of the best loser system and simulate the Korean best loser system with actual Japanese election results to forecast whether the Korean parties will use the Korean best loser system actively when the system is introduced. The Japanese big parties carry out the strategy recently to arrange dual candidates on upper and the same rank of the proportional representatives' list. It shows that the Japanese big parties think the Japanese best loser system is useful for their parties because the system generates the contamination effect. The contamination effect can be generated when the system is fair. The Korean best loser system, however, induces several points cannot assure the fairness. If the Korean best loser system is applied as it is, the contamination effect would be low. It causes the Korean parties' negative use of the system and the aim for the Regionalism relief, the ultimate reason for the Korean best loser system's introduction, would not be realized.
