为科学反映电网公司各年度投资能力的优良程度,客观地描述与评价其变化差异。首先,本文从经营效益、电网运行效率、电网安全、电网发展情况、社会效益等角度来构建电网企业投资能力评价指标体系。然后本文采用Z-Score法对指标进行无量纲化处理,分别运用序关系法和变异系数法来计算主、客观指标权重,运用基于主客观加权属性值一致化的组合赋权法来确定最终的组合指标权重,最后采用TOPSIS法来对电网投资能力的优良程度进行评价。对评价结果进行深入分析,溯源找到导致投资能力欠优良的本质原因,为管理者提供参考依据。
In order to scientifically reflect the fineness of each year’s investment ability of the power grid companies, objectively describe and evaluate the differences in their changes. First of all, this paper constructs the evaluation index system of investment ability of power grid enterprises from the aspects of business efficiency, grid operation efficiency, power grid security, grid development and social benefits. Then, this paper uses Z-Score method to conduct the non-dimensional treatment of indicators, respectively, using ordinal and variation coefficient method to calculate the weight of the main objective and objective indicators, and uses the combination weighting method based on the uniform subjective and objective weighted attribute values to determine the final Combined index weight, and finally use TOPSIS method to evaluate the goodness of grid investment ability. In-depth analysis of the evaluation results, traceability to find the cause of the investment ability of the underlying causes of poor, to provide a reference for managers.
