The aim of the paper is to identify determinants of the efficiency of service companies from two Central and Eastern European (CEE) countries4—Poland and Belarus. These transition economies represent different economic and systemic conditions. That is why it is worth analyzing whether external conditions determine internal efficiency factors in service companies. In order to achieve that aim quantitative research was conducted among 305 Polish and Belarusian service enterprises. The research results presented significant differences in responses between the two countries. For Polish enterprises the main determinants of efficiency were above all connected with competent and skilled staff. Belarussian companies regarded as efficiency factors which determine the demand level by means of access toward foreign markets and possibilities of internationalization. It proves that CEECs are not homogeneous and they represent different levels of economic development as well as the different conditions of running a business.
Knowledge-Intensive Business Services (KIBS) are services that involve intensive use of high technologies, specialized skills and professional knowledge. However, there are insufficient findings on the competences of employees in the sector of KIBS. The purpose of this paper is to present the results of the research on employees’ competences in different service sectors of two CEE countries: Poland and Belarus. This study adopted a quantitative approach based on a questionnaire applied to 101 companies from Poland and 42 companies from Belarus. The comparative analysis shows quite similar findings - the most significant competencies are employee engagement, motivation and customer-focused orientation and play a crucial role in the efficiency of services in both countries.
