Abstract

Serbian. У раду се анализирају утицаји структуре тржишта (распореда тржишних удела) и броја друштава за осигурање на степен концентрације (и конкуренције) у сектору осигурања у Србији )без Косова и Метохије) у току десетогодишњег периода 2011–2020. Као основа за анализу послужио је обрачун већег броја одговарајућих коефицијената концентрације, извршен у претходном ауторовом истраживању (Буквић 2021), на основу укупне премије осигурања. Разграничење утицаја наведених фактора извршено је према познатој декомпозицији Хиршман-Херфиндаловог индекса на две компоненте, у којима фигуришу наведени фактори. Показано је да су варијације иначе релативно високог степена концентрације биле под утицајем тржишне структуре (варијансе тржишних удела), с којом постоји позитивна иако и умерена корелација, али не и броја друштава за осигурање, с којим су остварена дивергентна и готово у потпуности некорелисана кретања. English. The paper analyses the impacts of the market structure (the distribution of market shares) and number of insurance companies on the degree of concentration (and competition) in insurance sector in Serbia (without Kosovo and Metohia) during the ten years period 2011–2020. As basis for the analysis the calculation of the many appropriated concentration indices was taken, which was made in previous author's research (Буквић 2021), on the basis of total premium. Separation of the impacts of two cited factors is made according the famous of Hirschmann-Herfindahl index to two components, in them these factors figure. It was demonstrated that relative high values of concentration indices were under the influence of market structure (variance of the market shares), with them there is positive although the moderate correlation, but no of number of insurance companies, with them the divergent and in whole no correlated moves was registered.
