The invention relates to an asset wall-based asset management forecast information processing method suitable for a power system. The method includes steps that an application server obtains value and commissioning distribution data of stock assets from a database server, and conducts integration in a data integration module; the data integration module inputs the value and the commissioning distribution data of the stock assets to an asset wall status analysis module for analysis, obtains the asset wall status of various types of assets, and stacks the various types of asset walls so as to form asset wall data of the whole asset of a company, which includes value scale asset wall data and technology scale asset wall data, wherein the value scale asset wall data are sent to a multi-dimensional scenario analysis and technical improvement prediction module, and the technology scale asset wall data are sent to an operation and maintenance prediction module; and the like. Compared with the prior art, the asset wall-based asset management forecast information processing method suitable for the power system has the advantages of predicting work amount of the operation and maintenance, providing data basis for operation and maintenance plan formulation of the company, improving quantification decision level of the company, and the like.
