Some descriptions were made about the species but the concentration of this segment has not been examined, that is why the aim of the researchers is to analyse the concentration of the Mangalica population on the basis of various statistical methods in the last 10 years. The certain concentration indexes were the following the concentration ratio, the Lorenz-curve, the Gini-coefficient, the Herfindahl-index and the redundancy index. Through the analysis we realised that from 2000 a kind of concentration started, which in case of the concentration ratio, the Lorenz-curve and the Gini-coefficient were in 2001 and 2003 of the highest ratio. The Herfindal-index and redundancy index showed that the years of 2000 and 2002 were the most significant, because of a number of large-scale producers started their activities or developed their stocks in these years. On the basis of the results, it can be stated that in the years before the application and after the recession the concentration of the stock was instable, while at the beginning of the supporting period until the crisis the appearance of large-scale firms became equal but basically according to every index the concentration in the examined years was approximately average.展开更多
