中国和东欧都进行了经济改革，但却导致了不同的结果，于是很有必要对他们的企业运作进行考察并作出比较．本文用多目标决策方法对来自中国、波兰、保加利亚和北美的４０家企业的经济效益进行了比较，并用多元统计分析中的对应分析考察不同同家的企业的不同特征．可以发现，北美企业更注重企业利润，并且也具有相对更好的经济效益；疲兰的企业虽然注重企业生产总量，但很多企业经济效益并不理想，几乎所有的企业都排在后２０位；中国和保加利亚的情况差不多，有１０％企业排在前１０位，４０％在前２０位
Both China and Eastern Europe have carried out economic reforms, but they have led to different results. Therefore, it is necessary to examine and compare the operations of their companies. This paper uses multi-objective decision-making methods to compare the economic benefits of 40 companies from China, Poland, Bulgaria and North America, and uses the corresponding analysis in multivariate statistical analysis to examine the different characteristics of different companies in the same family. It can be found that North American companies pay more attention to corporate profits and also have relatively better economic benefits. Although the enterprises in Welsh-Blue focus on the total production of enterprises, many companies have unfavorable economic results, and almost all of them are in the top 20 The situation in China and Bulgaria is similar, with 10% of companies ranked in the top 10 and 40% in the top 20.
