This thesis analyzes the influence that the semi-presidential form of government has on the degree of closure of party competition structures. Thus, using part of the axioms of the so-called Neo-Madisonian theory of party behavior and Mair's theoretical approach to party systems, the behavior of parties in government in Portugal (1976-2019) and Peru (1980-1991 and 2001-2019) is analyzed. The working hypotheses propose that the president-parliamentary form of government promotes a decrease in the degree of closure of party competition structures, whereas the premier-presidential form of government promotes either an increase or a decrease in the closure levels of said structures. The investigation results corroborate that apart from the system of government, the degree of closure depends on the combined effect of the following factors: whether the president's party controls Parliament, the concurrence or not of presidential and legislative elections, and whether the party competition is bipolar or multipolar.
