This study provides an overview of the origin, importance and strength of the non-leading cadre system and argues that the system plays a key role in building resilience in China's bureaucracy. The non-leading cadre system is administratively and politically important because it makes the party-state bureaucracy more adaptable and fosters cohesion among the elite cadre workforce. Although the system may appear to have institutionalized redundancy, this study argues that this redundancy has the benefit of making movement between leading and non-leading cadre status possible. In other words, the non-leading cadre system provides the various levels of the party-state bureaucracy with the leverage to develop their own measures for resolving their own problems. Putting aside the deficiencies in implementation, the non-leading cadre system is likely to remain durable and will help to develop an agile and resilient personnel management system, at least in the short to medium term.
