Achieving high performance is a crucial objective aimed by the management of any company. The accurate and efficient economic resources management contributes decisively to improving performance. The paper presents an econometric model that shows the link between economic performance and patrimony management reflected through a series of indicators, such as the return on current assets, fixed assets ratio and the funding structure of capitals (financial leverage). In terms of research tools, we used techniques of regression analysis based on specialized software. The obtained results allow drawing conclusions about the elements upon which decision makers should intervene in order to increase economic performance.
