回归分析在竞争力评价指标权重设定中的应用

The Application of the Regression Analysis in Setting Weights of the Competitiveness Index

指标体系是竞争力评价的核心,而指标权重又是指标体系的重要组成部分,选择不同方法设定指标权重会得到不同的评价结果,只有选择科学合理的指标权重设定方法,才能保证指标体系的客观性,提高竞争力综合评价结果的科学性。在总结传统指标权重设定方法局限性的基础上,分析指标和竞争力之间的关系,提出用回归分析法建立双对数模型和面板数据模型,度量各个基础指标对竞争力的影响,进而计算指标权重,是比较实用、有效的方法。

Index system is the core of competitiveness evaluation, and the index weight is the important part of the index system. Different method of setting index weight led to different evaluation results. It must select scientific and reasonable method of setting index weight to ensure the objectivity of index system and promote the scientificalness of the evaluation results of competitiveness. Based on summarizing the limitation of the traditional methods, the paper analyzed the relationship between indicators and competitiveness, proposed that it was a more practical and effective method of using regres- sion analysis to establish a log-log model and panel data models to measure the impact that indicators have done on competitiveness,and then calculate the weight for each indicator.
