Minority government is defined by the relationship between the legislative and executive branches of government in parliamentary democracies; it means single-party cabinet or coalition cabinet, which are not supported by a parliamentary majority in Parliamentary and Semi-Presidential countries. For instance, in Taiwan, Chen Shui-bian won the Presidential Election in 2000, but he just garnered 39.3¢Mof the popular vote, so he was a minority president. After election, the president Chen Shui-bian appointed Chang Chun-hsiung as Premier (Executive Yuan); therefore, ¡§Chen Shui-bian government¡¨ indeed was a minority government. Because the ¡§regime turnover¡¨ happened in Taiwan is the first time, as a ruling party, Democratic Progressive Party (DPP) didn¡¦t deal with very well in cabinet portfolios, policy concession or policy implementation. On the other hand, the political disturbance has been existed in the executive-legislative relations since 2000. Under this context, to understand why minority governments form and how they operate become an important issue. As we noted, there is not rich literature on minority governments, so this is why the study focus on initially exploring minority government. This essay includes two research subjects: The first point is to analyze theory of minority government. By following the documents of the scholars¡¦ comparison and research, I try to explain why a minority government form from the part of the institution and strategy; I also introduce the operation and performance of minority government briefly. The second point is to do the studies of cases of minority government and performance in Norway and Fourth Republic France: From the two empirical cases, I expect to find a suitable solution for the constitutional deadlock at present in Taiwan.
