The invention provides a method for dynamically configuring an index evaluation system. The method is characterized in that: a basic information table, a common library, a background application program unit and a scheduling program unit are provided. The method comprises the following steps of: 10, configuring an acquisition unit; 20, configuring an index unit, and self-defining an index calculation formula; 30, starting an acquisition program, acquiring acquisition data and storing the acquisition data in an acquisition table; 40, starting an index calculation program, realizing index calculation and storing index data in an index table; and 50, sending the index data to a customer. The method has the advantages that: the index evaluation system realizes the flexible configuration and calculation of an index, can define other indexes which are components of the index, supports self-definition of the calculation formula and the like, and solves the inflexibility of an index relation.The index evaluation system can be used by a user mastering skills; and as long as some pieces of basic data are set, the complete configuration of the user is realized by dragging and selection, andthe index evaluation system can be used after definition without participation of a developer, so that the development cost of the system is saved.
