This paper explores the linkage between electoral systems and candidate selection methods (CSMs) by analyzing two innovations of CSMs in Taiwan and Japan: polling primary and kobo, respectively. With an assumption that parties’ CSMs reflect their strategies to win elections, this article offers the rationale behind why and how major parties in Taiwan and Japan adjusted their CSMs to meet the challenges posed by the transition of electoral rules in each country from single non-transferable vote (SNTV) systems to mixed-member majoritarian (MMM) systems. We argue that a party's choice of CSMs reflects its rationale for maximizing the prospects of winning under the given electoral rule, which counters the ‘no-finding’ conclusion in some previous large-N studies on the linkage between electoral systems and choices of CSMs. Additionally, our findings highlight the importance of institutional factors, such as electoral systems, in explaining CSM reforms in a comparative perspective.
