基于实证方法的航空产业升级效果评价指标体系构建研究

本文提出了基于实证方法的航空产业升级效果评价指标体系的构建框架。该框架通过元分析法对相关文献进行筛选,建立了航空产业升级效果评价的初步指标体系;通过问卷调查的方式收集专家价值判断数据,以数据平均值判断指标重要性,删除评价重要性较低的指标;对剩余指标进行主成分分析,删除因子载荷系数较小、对产业升级效果评价影响较弱的指标;通过相关性分析将指标体系中对航空产业升级影响较弱的指标筛除,以克服信息冗余问题。最后,结合专家经验知识,依据主成分分析中的数据方差计算出指标信息量贡献比率为80%,从而验证了所构建指标体系的科学性;并通过算例验证了该指标体系的可行性。

Empirical Research on the Establishment of Evaluation Indicators for the Evaluation of the Effectiveness of Aviation Industry Upgrading

This paper constructs a framework of evaluation index system of aviation industrial upgrading effect based on the empirical method. On the basis of literature analysis and Delphi method, a preliminary index system for aviation industrial upgrading evaluation is established. By taking Shaanxi aviation industry as an example, we filter out the indicators which have weaker influences on Shaanxi aviation industry according to expert opinions. Then, we delete the indicators that have low component scores by using component analysis. In addition, we exclude the unimportant indicators of the two indicators having high correlation to overcome the problem of redundant information. Finally, by experience and knowledge of experts, and the contribution rate of index information amount, the eventual index system can reflect 80% of original information and its reliability is verified; and by an illustration example, the feasibility of this index system is also verified.
