按照信息论基本原理的解释，信息是系统有序程度的一个度量，熵是系统无序程度的一个度量;如果指标的信息熵越小，该指标提供的信息量越大，在综合评价中所起作用理当越大，权重就应该越高。(According to the basic principle of information theory, information is a measure of system order degree, and entropy is a measure of system disorder degree. If the information entropy of the index is smaller, the greater the amount of information provided by this index, the greater the role of the evaluation in the comprehensive evaluation, the higher the weight should be.)
