Abstract
This article is devoted to study and comparative analysis of the features and levels of support for new political parties during parliamentary elections in Ukraine, in particular the period 1998-2019. With this in mind, mainly based on the calculations of the indices of overall electoral volatility, intra-system electoral volatility and extra-system electoral volatility, we analyze the parameters of changes in electoral support (by voters) for political parties, in particular new ones, during the 1998-2019 parliamentary elections in Ukraine. In addition, we correlate overall, intra-system and extra-system electoral volatility, and present the correlation of overall electoral volatility in the sample of all political parties as the subjects of electoral processes in Ukraine and political parties elected to the national parliament (the Verkhovna Rada of Ukraine). As a result, the study outlines two clusters of extra-system electoral volatility, which show the highest level of similarity, and calculates the dependence of the level of electoral volatility and stability of the party system in Ukraine. With this background, we conclude that electoral volatility in Ukraine is largely determined by the effect of party affiliation or desire to belong to the government or opposition, and is regulated by the special context of identity politics in this country.
