From the perspective of grassroots governance, this paper selects 50 villages in 11 townships (management service centers) of Zhangzi County, Changzhi City, Shanxi Province as the research objects.By applying the Analytic Hierarchy Process – Entropy Method – TOPSIS analysis method to construct a TOPSIS comprehensive evaluation model for the statistical service capability evaluation system, it systematically explores the mechanism of “statistical services” in supporting the rural revitalization strategy from four aspects: “data support – resource allocation – policy optimization – governance innovation”.The experimental results show that among the weights of the indicators obtained under the TOPSIS comprehensive evaluation model of this paper, among which the digital quality is 0.342, the informatization level is 0.267, the synergistic ability is 0.228 and the service efficiency is 0.163, after the comprehensive assessment of TOPSIS, the relative proximity of each township of the sample villages is in the range of 0.712-0.983, and there are 12 townships reaching the excellent level accounting for 24.0%. Through quantitative analysis, the study clarifies the main pathways for improving statistical service capability in Zhangzi County, Changzhi City, Shanxi Province, and explores a practical and operable path for realizing the coordinated development of rural revitalization and grassroots statistical work.
