Utjecaj izbornog sustava na oblikovanje stranačkog sustava i Vlade u Republici Hrvatskoj 1990 - 2007.

The paper analyses all electoral systems according to which Croatia has conducted its parliamentary elections in the period between 1990 and 2007, and the influence of each electoral system on the party system and the formation of government in Croatia. One of the most important particularities of Croatian elections have been frequent changes of electoral laws and electoral systems by which the elections have been conducted, and therefore it is hard to find a country which has changed so many different electoral systems in a relatively short period. In the first ten years of existence of Croatian democratic state all major electoral systems have been used: double ballot majority system, mixed plurality -- proportional system, and finally proportional system since 1999. Analysing the formation of government based on different electoral systems the authors offer different answers as to the best possible electoral system -- one of them arguing for a more proportionate system (election of more representatives in each electoral unit, smaller prohibitive clause) which could lead to a more representative parliament with coalition governments, the other arguing for a double ballot majority system, which could reshape the Croatian party system in a bipolar mold, and help in forming a stable government.
