Abstract

This study aimed to analyze the minutes of the Legislation and Judiciary Committee, one of the standing committees of the Korean National Assembly, by applying the WORDFISH algorithm of automated text analysis to estimate the pattern of changes in the ideological orientation of the members of Korea's political elite. The results of the analysis showed that the Legislation and Judiciary Committee generally undergoes changes in ideological orientation around the time of a major administrative change, especially during the period preceding a change up to the time of its implementation. Compared with the United States, where changes in the ideological orientation of the political elite occur simultaneously based on parties, changes in that of the political elite at the Korean National Assembly tend to occur in response to a certain transitional point in time or a change in the ruling government. What is especially noteworthy in terms of the ideological orientation reflected in the minutes of the Legislative Judiciary Committee is that the microscopic effect tends to disappear when the macroscopic effect occurs and, conversely, that the microscopic effect emerges once the macroscopic effect has disappeared. In other words, changes in the ideological orientation of the political elite appear to indicate the effect of a particular legislator's individual characteristics when no effect is observed during a given term or year of the National Assembly, whereas they revealed the effect of a given time itself when no effects related with the individual characteristics of a legislator are discerned.

이 연구는 국회 상임위원회 법제사법위원회 회의록을 분석 대상으로 자동화된 텍스트 분석 방법의 WORDFISH 알고리즘을 적용해 정치엘리트의 이념성향 변화 패턴을 추정하였다. 법제사법위원회의 경우 행정부 교체 전후의 간기(間期)에서 이념성향의 변화를 겪고 있었다. 한국 국회 내 이념성향의 변화는 미국의 경우에서처럼 정당을 중심으로 동시적으로 이루어지기보다는 한 시점의 이념성향에 대한 반응 혹은 집권 정부의 교체에 대한 반응에 따라 변화되고 있다. 법제사법위원회 회의록에 나타난 이념성향의 변화는 국회 대수별, 연도별 시기적 효과가 발생하지 않을 때 국회의원 소속 정당의 이념성향, 선수(選數) 등 개인의 특성 효과가 나타나고, 개인의 특성 효과가 나타나지 않을 때 시기 자체의 효과가 나타났다. 즉, 이념성향 변화를 추동하는 거시적 효과가 발생할 때 미시적 효과가 사라지고, 거시적 효과가 사라질 경우 미시적 효과가 나타난 것이 확인되었다.
