Marże marketingowe i wartości dodane w łańcuchu dostaw żywności w Polsce
The issue of agricultural producer participation in the final food price is of interest to scientists and politicians. The European Commission (2014, 2016) commissioned the preparation of expertise in this area, as a result of which actions were taken to strengthen the agricultural sector. In Poland, for example, the promotion of direct sales has been intensified. These activities are aimed at shortening the food supply chain and improving the market power of agricultural producers. Market power means the ability of an enterprise to increase the price of its own product without reducing the level of sales to competitors. The aim of the research was to indicate trends in the area of marketing margins and added value in the food supply chain. This measurement served the search for the answer - which product groups have the highest level of added value and the greatest ability to improve the income of agricultural producers? The estimation of the value added illustrates - where does the "food zloty" of the final consumer go?
