7. The Relationship between Mainstream and Movement Parties in Taiwan. Case Studies of the New Power Party (NPP) and the Green Party Taiwan-Social Democratic Party Alliance (GPT/SDP)

Since democratization began in the mid-1980s, Taiwan’s party system has been dominated by two parties, the Kuomintang (KMT) and the Democratic Progressive Party (DPP). However, smaller parties have at times played an important role, bringing diversity into the system, stressing different issues and representing neglected communities. These small parties tended to be those that split off from the mainstream parties, while alternative social movement parties struggled to be electorally relevant. The picture changed recently with the rise of two different types of movement parties, the New Power Party (NPP) and the Green Party Taiwan/Social Democratic Party Alliance (GPT/SDP). In this chapter we examine the relationship of these new players with the mainstream party, DPP, offering some thoughts on how the relationship affected the development of these alternative parties.
