Abstract

Serbian: U radu su istraženi oblici konkurencije na robnim tržištima. Na osnovu podataka iz završnih računa preduzeća za 1994. godinu formirani su koeficijenti koncentracije K1, K2, K4 i K6 za ukupno 185 privrednih grupacija iz industrije, poljoprivrede i šumarstva (robna tržišta). Primenom navedenih koeficijenata, u iterativnom postupku i uz korišćenje klaster analize, identifikovano je ukupno 12 tipova konkurencije. Najpre su određeni monopol (K1=100%), duopol (K2=100%, ali s približnom jednakošću dvaju proizvođača) i konkurencija (K4<40%), a zatim u drugom koraku ostali tipovi konkurencije. U njihovom razvrstavanju primenjena je klaster analiza na sva četiri koeficijenta koncentracije. Rezultati analize ukazali su na globalno visok stepen koncentracije i shodno tome preovladavanje oblika neefektivne konkurencije, a njihov raspored u po posmatranim privrednim grupacijama treba da bude okvir za izgradnju efikasne, diferencirane ekonomske politike usmerene ka izgradnji konkurentnih tržišnih uslova privređivanja.

English: The paper investigates the forms of competition in the commodity markets. Based on the data from the final accounts of companies for 1994, concentration coefficients K1, K2, K4 and K6 were formed for a total of 185 business groups from industry, agriculture and forestry (commodity markets). By applying the aforementioned coefficients, in an iterative procedure and with the use of cluster analysis, a total of 12 types of competition were identified. First, monopoly (K1=100%), duopoly (K2=100%, but with approximate equality of two producers) and competition (K4<40%) were determined, and then, in the second step, other types of competition. In their classification, cluster analysis was applied to all four concentration coefficients. The results of the analysis indicated a globally high degree of concentration and, accordingly, the prevalence of forms of ineffective competition, and their arrangement in the observed economic groups should be a framework for building an efficient, differentiated economic policy aimed at building competitive market conditions for business.
