Explanation of spatial differentiation of electoral results in the Czech Republic and Slovak Republic

This article explains the basis for electoral support for political parties in the Czech and Slovak Republics in the post-1993 period. The database consists of results from Parliamentary elections (in the Czech context, elections to the Chamber of Deputies) and of data obtained from censuses carried out by statistical agencies. The theory of conflict lines developed by Stein Rokkan and Seymour M. Lipset was chosen as the theoretical basis. The key analytical tool employed is linear regression. The explanation provided evaluates the dependence of political party electoral support (as defined by seats won in elections) upon socioeconomic variables contained in the theory. Analysis of the results shows that the support parties receive in elections depends significantly upon social characteristics. An especially clear explanation is generated for the support given to Christian and ethnic parties. For protest parties, the impact of the constituent social and economic structure is only marginal.
