Study on the Gray Correlation Degree of Economy-Environment-Society System Based on Entropy Weighted

With the grey correlation methods of the grey system theory , the paper study on the coordination degree quantitative models of economy-environment-society structure on BinXian. According to the variation of each index, the weight coefficients in the model are derived from the avail value of data reflected by the information entropy, the subjective influence of weight allocation can be avoided effectively. The analysis results of coordination degree by the method of entropy-weighted gray correlation analysis had shown the evolution process of coordination degree, give a reasonable analysis.
