This study identifies and interprets dominant developments in the Taiwanese literary field by examining data included in publication catalogs of literary journals and supplements from 1940 to 1953. Utilizing social network analysis, it focuses on both ruptures caused by crucial political events and continuities that spanned these ruptures. The study revisits central tenets of Taiwanese literary history and, by seeking to articulate structuring principles, also unveils new perspectives on how to map and interpret the dynamics of literary systems and the ways in which they mesh with society. It thereby exemplifies how digital humanities can guide researchers toward new historical insights.
