Data Processing in the Application of Grey Relational Analysis Model in Regional Economic Openness of Evaluation System

Abstract:

In the process of multi index analysis and evaluation, the index value is normalized and standardized through non-dimensional processing of the original data. The index weight is determined according to each index relative principal component contribution through principal component analysis and principal component extraction. Then, a combined evaluation model will be formed through the grey relational analysis, calculation of each index according to grey weighted relative degree. Scientific applicability of the model will be evaluated through regional economic opening degrees.
