Embodiment Construction

[0048] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] In the first aspect, the embodiment of the present invention provides a method for selecting evaluation indicators based on data envelopment analysis, such as figure 1 shown, including:

[0050] S1. Collect all input indicators and output indicators, and determine n main input indicators and m main output indicators according to the indicator selection principle, where n and m are positive integers;

[0051] S2. Perform a correlation analysis on the n main input indicators, and determine at least two main input indicators with the strongest correlation;

[0052] S3. Using the above-mentioned at least two main input indicators and m main output indicators to establ...

Abstract

The invention relates to an assessment index selection method and device based on data envelopment analysis. The method comprises that S1) n main investment indexes and m main output indexes are determined according to an index selection principle; S2) at least two main investment indexes of highest correlation are determined in the n main investment indexes; S3) the at least two main investment indexes and m main output indexes are used to establish a basic model of data envelopment analysis; S4) the efficiency value of each main investment index is obtained according to the residual main investment indexes and the above model; S5) the change exceeding rate of the efficiency value is obtained; S6) if the change exceeding rate of the efficiency value exceeds a second preset value, the corresponding main investment index is introduced to the model to form a new data envelopment analysis model which serves as the basic model for data envelopment analysis, and S4) is returned to; and S7) and if the changing exceeding rate of the efficiency value is lower than the second preset value, the main investment model of the basic model serves as a final investment index. According to the method and device, manual index selection is not needed, and the objectivity of assessment can be improved.

Description

technical field [0001] The invention relates to a data evaluation method, in particular to a data envelopment analysis-based evaluation index selection method. Background technique [0002] Data Envelope Analysis (Data Envelopment Analysis, DEA) is a commonly used efficiency evaluation method, which is used to evaluate the relative efficiency among a group of Decision Making Units (DMUs) with multiple inputs and multiple outputs. In 1978, Chames, Cooper and Rhodes proposed the first DEA model, which was named the data envelopment analysis model. The model is very effective in evaluating the scale effectiveness and technical effectiveness of multi-input multi-output DMU. [0003] When using the data envelopment analysis method, it is necessary to select different evaluation indicators according to different evaluation purposes. At present, the methods for selecting evaluation indicators mainly include principal component analysis and factor analysis. Among them, Alder and ...
