The invention provides a whole-process differentiated multi-dimensional classification management strategy for full-category projects. The strategy comprises the steps: S1, performing policy analysisunder an electricity transformation background; S2, analyzing the influence of policies on a whole-process differential multi-dimensional classification management strategy of the full-category project; S3, constructing a comprehensive plan index system according to an analysis result of the step S2; and S4, creating a project management mode and a management mechanism adaptive to electricity modification. According to the whole-process differentiated multi-dimensional classification management strategy for full-category projects, under the background of electric modification, comprehensive management of all projects can be rapidly and effectively achieved, the management levels are clear, and finally full-category project whole-process differentiated multi-dimensional classification management of the whole electric power project is achieved.
