Government performance evaluation has a long history. However, major differences of opinion regarding its role still exist both in Western and Chinese academia, from theoretical, and practical perspectives. In this article, we conduct an empirical measurement of the role played by government performance evaluation and construct a regression model to explore the major factors influencing public officials’ perception, relying on survey data from a district government of county level in Guangdong Province. The study reveals that the average value of 14 items measuring government performance evaluation was 3.36 points (out of a possible 5 points). The role of the government in setting annual objectives, tasks, and priorities, as well as strategic planning, and target setting, and strengthening departmental accountability, had the most significant effect on the perception of efficacy of performance evaluation, whereas departmental budget setting, resource allocation, and reduction of operating costs had the least effect. Furthermore, performance communication and feedback, as well as the validity of the performance indicator system, also significantly influence the perception of the role played by government performance evaluation. The article concludes with a discussion of the differences between government performance evaluation in the West and in China.
