Globalization processes, welfare global increase and transnational corporation development lead to an increase of the international trade turnover. At the same time, the capacity of existing international transport corridors is limited by natural causes, and the formation and development of new international transport corridors is a lingering and expensive investment process with an unpredictable level of profitability. In this regard, increasing load on the existing international transport corridors leads to efficiency decrease, and the loss of international transport corridor sustainability, which is more dangerous for international trade. These phenomena lead to the necessity of investment in research of sustainability insurance and direction development of these international transport corridors. Of particular importance is the sustainability of the international transport corridor for the agricultural products international trade, since this kind of products imposes a lot of restrictions on their transportation. The key research question is how the dynamics of the international transport corridor development influences on the dynamics of exports of agricultural goods. The purpose of this research is to explore the vectors of world agricultural markets development under the influence of the key international transport corridor transformation. The authors investigated external factors that influence the functioning of the Northern Sea Route, the Trans-Siberian Railway and the Suez Canal. The methodology of this study is based on the classical methodology of the regression analysis. The results of the research were aggregated into an econometric model, allowing to evaluate the impact of changes in the external factors on the development of the studied international transport corridors and, as a result, the development of agricultural product international markets.
