Routine Problems: Movement Party Institutionalization and the Case of Taiwan's New Power Party

Why do some movement parties successfully institutionalize into a functioning party organization while others struggle? This paper argues that not all movement parties institutionalize in the same way. Movement parties that emanate out of a long-term social movement organization face a qualitatively different set of challenges than those that form out of a short-term movement. Routinization-the process of parties developing rules, regulation, and predictable behavior-is a particularly crucial component for short-term movement party institutionalization. When parties emanate out of long-standing social movement organizations, they are advantaged because they already have existing formal rules and regulations. Short-term parties however, are disadvantaged because they lack these organizational structures. Further, short-term movement parties not only need routinization, but must make it a priority; the sequencing of their institutionalization matters. I demonstrate the importance of routinization with the case of Taiwan's New Power Party, a movement party formed out of the 2014 Sunflower Movement. This case shows how struggles to routinize early for short-term movement parties leads to crucial causal mechanisms hindering party institutionalization instead of helping it.
