Taking the "Weilinli" platform in Community B， Wuhan City as a case， this study reveals the practical manifestations and formation mechanisms of "technocracy suspension" in mega-city community governance. The findings indicate that "technocracy suspension" in mega-city communities is specifically characterized by involution of subject capacity， solidification of participation barriers， suspension of data resources， and obscuration of public values. Its formation stems from the incompatible tension between technical attributes and the governance scenario of mega-city communities， namely the contradiction between the reductionist attribute of technology and the "ultra-heterogeneous" governance demands， the disembeddedness between technocratic instrumentalism and the "ultra-complex" governance structure， the tension between rigid technical constraints and the "ultra-dynamic" governance scenarios， and the deviation between technical instrumental rationality and the people-centered governance philosophy. Accordingly， remediation strategies for "technocracy adaptation" are proposed from the dimensions of subject capacity， participation structure， data scenarios and value concepts. This research helps deepen the understanding of the causes of the "technocracy suspension" phenomenon and provides references for promoting the quality and efficiency improvement of digital governance in mega-cities.
