ABSTRACT

In this conducted study, socio-economical developmental index of European Union Candidate country and some selected countries is calculated with factor analysis and data envelopment analysis (DEA). For calculating this index 2008 year macro economical indicators are used. Data envelopment analysis is an approach of measuring efficiency of homogeneous units. In the analysis, the efficieny scores which are calculated with DEA are accepted development index of countries. DEA‟s decomposion power of efficient and nonefficient countries are decreased ıf the variable number is too much. For this reason all the variables in factor analysis couldn‟t use in the analysis. On the othe hand, countries are ranked with factor analysis according to factor loadings and compared with DEA ranking and are determined dissimilarities.
