For researchers studying Chinese politics, the concern is not whether factions are important, but rather how to identify them. In the Chinese context, factional affiliations are often concealed, requiring researchers to devote extensive efforts to parse them. Faction detection methods have transformed over time, from the “rumours-have-it” approach of first-generation scholars, to the “backgrounds-in-common” framing of the second generation, and the “practices-of-patronage” focus of the current generation. This article offers a systematic review of these approaches and finds Junyan Jiang’s patronage-focused, “within-tenure promotion” approach to be the most accessible and justifiable. Building on Jiang’s work, we propose two additional criteria to this identification method, “double promotion” and “promotional grooming.” Finally, we test all the verifiable approaches against the odds of China’s prefectural-level leaders crossing career thresholds between 2000 and 2020. The test results show that the background-based approach has limited validity and Jiang’s patronage-based approach thus requires further refinement. In contrast, our revised identification methods prove to be effective in clarifying the factional factor. This study thus proposes an improved, verified approach to identifying factions in Chinese politics and provides researchers with a reliable tool for identifying the “people factor” in the comparative study of political elites.
