Abstract: Based on Maslach's theories of job burnout and job matching， three evaluation indicators， namely， low mood， split personality and lack of achievement are determined after in-depth interviews and literature review. Three influencing factors， namely， difficulty in occupational control， low occupational value and inadequate occupational motivation， are also identified. Nine hypothetical relationships among the three evaluation indicators and three influencing factors are established. The influence mechanism of influencing factors on civil servants' job burnout is verified， and the differences of different statistical attributes on the sense of job burnout among customs civil servants are analyzed. The data shows that occupational control difficulties can easily lead to low mood， lower professional value can lead to low mood， split personality， and lack of sense of accomplishment and professional incentives can lead to personality split.

Key words: grassroots civil servants, job burnout, occupational value
