一种基于EVA的数据价值评估模型的建模方法
摘要：
本发明涉及一种基于EVA的数据价值评估模型的建模方法，包括以下步骤：(1)获取数据建设费用J，并计算数据运维费用Y；(2)根据获取数据建设费用J和数据运维费用Y，计算数据成本：P0＝J+Y；(3)计算经济增加值：EVA＝W0-J，其中，EVA表示经济增加值，W0表示数据应用经济效益，J表示数据建设费用；(4)建立数据价值评估模型。本发明使得数据的内在价值和使用价值有一个量化指标，实现对数据进行多角度价值评估，实现信息系统数据价值的量化表示，促进了信息系统数据管理的优化。
摘要（英）：

The invention relates to an EVA (economic value added)-based modeling method of a data value evaluation model. The method includes the following steps that: (1) data construction cost J is obtained, and data operation cost Y is calculated; (2) data cost P0 is calculated according to the data construction cost J and the data operation cost Y based on a formula that P0=J+Y; (3) an economic value added (EVA) is calculated according to a formula that EVA=W0-J, wherein EVA represents the economic value added, W0 represents data application economic benefits, and J represents the data construction cost; and (4) the data value valuation model is constructed. With the EVA (economic value added)-based modeling method of the data value evaluation model of the invention adopted, the internal value and use value of data can be expressed as quantitative indexes, multi-angle value evaluation on the data can be realized, the quantitative representation of the data value of an information system can be achieved, and the optimization of the data management of the information system can be promoted.
