基于主成分分析的航天企业风险评价研究

基于我国我数航天企业正处于从计划经济到市场经济转轨阶段的现实，对比航天企业经济效益综合评估的诸多方法，综合考虑主成分分析法具有全面性、可比性、合理性和可行性等优点，建立了一套较为科学的航天企业风险评价方法，即在确立航天企业风险评价指标体系的基础上，运用主成分分析方法对风险指标体系进行科学的分析化筒，通过资信评价对航天企业风险状况展开评判。最后，结合实例作了进一步具有的说明。

Research on aerospace enterprise risk evaluation based on principal component analysis

Basing on the present situation that many aerospace enterprises of our country are in reform stage from plan economics to market economics,compared with many evaluation method of enterprise economic benefit,conssdered the advantages of principal component analysis which has the excellent characteristics of comprehensiveness,comparability,rationality and feasibility,a scientific aerospace enterprise's risk evaluation model is set up.That is,on the basis of establishing the risk index system of the aerospace enterprise risk evaluation,the principal component analysis is used to scientifically analyze and simplify the risk index factors.Then the risk of the enterprises by crediting evaluation is judged.At last,a numerical example illustrates the proposed method.
