Abstract
The number of enterprises, respectively their structure by fields of activity, influences the level of the national economy, so it is extremely important to know the “map” of economic agents in terms of evolution and level of competition by areas of activity. The purpose of this paper is to present in a descriptive way the evolution of the number and structure of active enterprises in Romania (by legal form and field of activity), as well as a comparative presentation of the situation of enterprises in Hungary and Poland. In all three countries, the total number of enterprises shows a continuous growth trend, but with significant differences in the growth rate, analyzed by areas of activity.
