In this research, we have applied the following indexes: RXA, RTA, ln RXA, RC, RCA, LFI, GL, Sm. We have examined the movement of the index for the period 2005-2011th year. We have investigated the existence of correlations RCA index of processed food sectors with the application of the Pearson and Spearman index determined as RCA variable mutual co-variant. We found that following products showed an increase of comparative advantage in export as measured by the Balassa index: milk products, cheese and curd, groats and meal of other cereals, preparations of cereals, flour, starch, vegetables, roots and tubers, processed, prepared and Fruit products, sugar, molasses and honey, chocolate and other food preparations with cocoa, animal food (including un milled cereals), edible products and preparations, alcoholic beverages, non-alcoholic beverages, solid vegetable fats, oils, ' soft ' and animal and vegetable fats.

Liquidity and profitability are closely related economic categories. The issue of constant balancing between liquidity and profitability, in theory known as "liquidity-profitability trade off", has been the subject of significant interest of the scientific community. There is no consensus on the direction of the impact of liquidity on profitability, but the existence of this impact in practice is confirmed. The aim of this paper is to investigate the impact of liquidity on profitability, based on selected traditional financial indicators, for medium and large enterprises in the group of processing and preserving of meat and meat products of the Republic of Serbia, in the period 2016 to 2019. The findings of a multiple linear regression analysis, show that the ratio of long-term sources and fixed assets in the group of processing and preserving of meat and meat products makes a statistically significant contribution predicting the return on assets.

Summary Serbia has a long tradition in thermal baths tourism development. In the second half of the

Wine production in the Republic of Serbia has a long tradition and potential for improvement, given the agro-climatic and other conditions. The aim of this paper is to analyze the competitiveness factors of wineries in the Republic of Serbia. The findings show that the wine industry is developing, but its' competitiveness is at a relatively low level. In order to strengthen the competitiveness of the wine sector, it is necessary to define and implement a strategy, which will include activities such as modernization of grape processing technology, new investments and investment in human resources, marketing, winemakers' association and creating a stimulating business climate. Without state support, a significant increase in the competitiveness of wineries cannot be expected. Since interest in wine production has been recently growing, it is to be expected that the wine production, as well as its' export will increase, thus achieving significantly greater economic effects.
