The aim of this article is to present a two-step analysis of a market orientation database about the Hungarian food processing small and middle sized enterprises (SMEs). There are two different scales describing the market orientation, the MARKOR and the MKTOR; we ascertain about their features if they are sufficient for the hypotheses of discriminative capacity and one-dimensionality. As a method for data analysis we used the structural equation modeling. After the calculations we state that one-dimensionality successfully fits from six features in case of five. We found that these features which are fitting to one-dimensionality have significant discriminative capacity.
