As work pressure accumulates over time, employees experience profound fatigue, ultimately leading to decreased job satisfaction among grassroots civil servants. In response, this study investigates the relationship between civil servant incentive mechanisms and job satisfaction based on meta-analysis. Computer-based literature retrieval was employed to gather relevant studies on the relationship between civil servant incentive mechanisms and job satisfaction. Applicable references were screened using exclusion criteria, providing data support for subsequent research analysis. Research variables and hypotheses were defined, and the research design was finalized. Guided by this framework, an investigation into the relationship between civil servant incentive mechanisms and job satisfaction was conducted. The Q-statistic for the relationship between civil servant incentive mechanisms and job satisfaction was Q=224.408, satisfying Q>k-1, indicating heterogeneity and correlation between the variables. Additionally, the Nfs value was 8172, failing to meet Nfs<5K+10, thus confirming no publication bias. Given the heterogeneity issue, an analysis of the moderating effect of job type on the relationship was supplemented. With P<0.05 for all variables, the moderating role of job type was confirmed.
