Abstract：Aiming at the development characteristics of small and medium-sized enterprises ( SMEs ) , a performance evaluation model in the dimension of management status and development potential for SMEs is put forward and the model is validated analytical with 171 SMEs data from gem .Taking into account the large number of businesses , a typical business sample selection policy relying on the cluster analysis meth-od is presented , and then dominance rough set theory incorporated into the performance evaluation model to provide the decision rules generation for SMEs performance evaluation by expert knowledge learning . Thus, a two-dimensional performance evaluation model for SMEs is constructed .The evaluation results show that there are few SMEs with both excellent status quo and development potential .In addition , the relationship between the quality of rough set classification algorithm and the size of training samples is dis -cussed.Results show that there is over fitting phenomena in learning classification of rough set , i.e., in-creasing the number of training samples is not necessarily able to improve the learning quality of classifica -tion.
