Since the early 1990s, the Chinese Communist Party (CCP) has put in place a series of measures to allow more Party members to participate in the cadre selection process. “Intra-party democracy” was promoted as a remedy to solve the corruption and social tension that resulted from overly concentrated personnel power. How effective are these formal procedures in constraining the appointment power of core Party leaders and institutionalizing the influence of a larger group of cadres? Drawing on archival research, interviews and quantitative data, this paper examines two components of intra-party democratic reform: “democratic recommendation,” which serves as a gateway to cadre promotion, and the semi-competitive elections at Party congresses. This in-depth study finds that the efforts to expand bottom-up participation are hindered by loopholes in formal regulations, informal practices and the frequent rotation of Party officials. Meanwhile, the reform measures have brought changes to the personnel system by complicating the Party secretaries' exercise of appointment power and altering the incentives of ambitious cadres. The implementation of intra-party democracy could improve the vitality of one-party rule, and its ebbs and flows imply a divide within China's top leadership over the direction of political change.
