Title: Agribusiness - a scope as well as an opportunity for contemporary agriculture
Abstract: The contribution deals with the key issues of contemporary food economy development as a system and its economic implication in regard to changing position of agricultural enterprises. It explicates why globalisation and integration processes have changed the structure and the interrelationships along the food commodity chains and have created completely the new economic environment for production agriculture. Based upon the economic theory outcomes the essential topics related to the problems why agriculture is largely influenced by the final stages of agri-food commodity chains are explained there. The active response on the demand structural changes include is perceived as a needful precondition of competitiveness of agricultural enterprises for future in general.

Title: Price transmission and estimations of price elasticity of secondary demand functions: application on commodity market for food grains
Abstract: The paper is focused on the quantitative analysis of the price transmission and on its use for the estimations of the direct price elasticity of the vertical-derived demand functions. The price transmissions were examined between the commodity markets for the food grain and the consumer markets for the bakery products and flour. The data (1995-2002) were taken over from the Czech Statistical Office (CSO), the Price Statistics (PS) and the Statistics of Family Budgets (SFB). The intensity of the inter-market price transmission was assessed by means of the coefficients of the price transmission elasticity (EPT). For enumerating of EPT, the regression linear models were developed. The explicit as well as the implicit time-definition in the models was tested. The explicit dynamic construction was carried out on the basis of the stationary process with the parabolic trend. After the determination of trend functions, the seasonal component in used time-series was thoroughly investigated by means of the harmonic analysis (G-tests of the individual extremes of the developed periodograms). The implicit dynamization of the linear models was solved on the basis of the first differences of appropriate commodity prices, respectively price levels on the consumer market. For the quantification of the price transmission elasticities, directly dynamized models there were only used only because the model unambiguously achieved better values of characteristics of the statistic verification (correlation index, F-test, T-test). These models also satisfied the economic assumptions in the sense of the vertical price transmissions between the observed market levels and the preservation of the law of diminishing demand. Based on the linear models of the price transmission with parabolic-trend stationarization, it was found out that within the observed period (1995-2002) EPT between commodity market with the food wheat and consumer market with the bakery products and flour reached the average level of +0.1602%. Within the same period, the value of EPT between commodity market with the rye and consumer market with the bakery products and flour reached the average level of +0.1067%. These coefficients were subsequently used together with coefficients of the own price elasticity of consumer demand for the bakery products and flour (ε) to the estimations of the own price elasticity of the commodity demand for food wheat and rye (e). In accordance with the construction of these estimations: e = ε × EPT, it was found out that the average level of the own price elasticity of the demand for food wheat (respectively rye) is about -0.0659% (respectively -0.0441%). Both observed secondary demand functions are therefore strongly inelastic with respect to the reaction on the direct price changes. The commodity demand for the rye seems to be more inelastic.

Title: Current situation of demand for organic products in the Czech Republic
Abstract: The paper is focused on the analysis of consumers' interest as one of the limit factor of demand for organic products. Consumers'interest is derived from questionnaire survey, which includes direct consumers as well as retailers with bio-products.

Title: Analysis of current situation in sales of selected organic products in the Czech Republic
Abstract: The paper deals with the analysis of current situation in sales of selected bio-products in the conditions of the Czech Republic. It is focused on the structure of plant and animal products, sold quantities, product prices, conditions of sale, common distribution channels and so on. Selected organic products are divided into two groups for the purpose of this analysis - products coming from producer to consumer through distributor and products coming to consumer through processor and distributor.
Keywords: organic products, market of organic products, consumption of organic products

Title: Supplier-industries of brewing and wine-production in the Czech Republic and their development
Abstract: The paper compares the main factors influencing the key supplier-industries for brewing and wine-production in the Czech Republic - hop-growing and winegrowing - and it is a part of a more extensive research focused especially on the processing industries, and the specifics of their analyses. The importance of hop-growing and winegrowing is based on the fact that they significantly influence not only the final product, but also the competitiveness in the successive industries of the product vertical. Similar influence within the examined industries is evidenced in the close interconnection with the above-mentioned (main) successive processing-part, and in the complicated position of the small growers. Differences are shown especially in the flexibility of reaction to the changes of demand for final products of the successive industries, and also in the position of both industries in the Czech Republic, and in the world.

Title: Comparison of analyses of winegrowing and wine-production in the Czech Republic, the EU, and South Africa
Abstract: The area of vineyards has increased to 19 261.5 hectares and the number of wine producers to 18.292 by 1 May 2004. This branch needs a long-term study that will lead to the establishment of the new politics for viniculture and wine-growing, related to the needs of the region. The trends are compared to the main European producer - France, and another country from the so called "New World"- the South African Republic. The researches are focused on the consumption of wine by population, share in the gross national product, employment in this branch, areas of vineyards, and number of wine-growers.
Keywords: politics, branch, viniculture, wine-growing

Title: The formalization of knowledge in agricultural industry business processes
Abstract: This article deals with the most important part of business modelling, with business process modelling. The presented process models are achieved by using common and special UML diagrams. The business process is one of the four basic business concepts creating complex business architecture and it is dynamic, structured and complicated part of the business. In business process, there are stored significant rules and knowledge of the business. Those issues could be applicable to the knowledge formalization in the agricultural business
