Abstract: We examine the factors shaping the formation of dynamic legislative co-sponsorship networks using unique data from the 20th Korean National Assembly. By employing dynamic probit, Poisson regression, and log-linear models, we explore the drivers of collaboration among lawmakers. Korea’s mandatory co-sponsorship requirements provide extensive data, enabling the analysis of dynamic network formation and path dependencies. Path dependence significantly influences co-sponsorship networks, attenuates partisan effects, and exerts a stronger impact across than within parties. Lawmakers are more likely to co-sponsor bills when they share legislative interests such as representing the same region and serving on the same committee.
