Various sources of investment resources for the agricultural sector are examined: raised funds, borrowed funds, budgetary funds, enterprises and organizations’ own funds. The article has revealed the functional features of investments which require state support. The paper outlines the specific features of the agricultural sector in the Republic of Crimea and its importance for the regional economy; state support of different regions of the Republic should be adapted in view of these features.

The article highlights the priority measures aimed at boosting the investment process in the agricultural sector: the development of the infrastructure directly affecting the production efficiency, state support for project activities: advisory assistance in developing investment projects, finding and attracting investors, targeted state financing of investment projects aimed at modernizing agricultural production and increasing its efficiency. We have found the goals, tasks and priorities of state support of investment activities in the agricultural sector as well as the results expected from the implementation of these directions of support.
