Logistic Regression Analysis

This study examines how structures of the party support have changed in Japan in the last twenty years. Using data of the Social Stratification and Social Mobility survey (SSM 1985) and Japan Survey on information Society (JIS 2004), it was found that characters of Liberal-Democratic Party (LDP) supporters as well as of political independents have changed following respects. (1) The effect of occupation (Agriculture and Forestry, self-owned business) on LDP support has dissolved. (2)The effect of city scale on LDP support has dissolved. (3)The positive correlation between life satisfaction and support to the LDP appeared in 2004. (4)The negative correlation between life satisfaction and political independents appeared in 2004. In last twenty years, social attitudes replaced social position as determinants of LDP support and of political independents. From results of analyses, this analytic model is useful. The support structure of the Democratic Party power is needed to be analyzed in the future research.
