We use multi-region Input-Output databases to show the sustainability of the Polish trade system. Analyses of the robustness of the supply system as a whole are missing in the literature, in strong contrast with a wide variety of network analyses inquiring into the resilience of financial systems. We represent the trade system as a flow network, and use information-theoretic approach to address growth and development of such a system. We perform: an analysis of the development, robustness, and structural sustainability of the Polish trade system based on national Input-Output Tables (in current prices) for Poland for the years between 1995 and 2011. As such, we are also able to comment on the changes of the studied characteristics over the years. Further, we compare the results with the results obtained for the global supply system based on the multi-region Input-Output Tables. We find the Polish supply system to be much less organised than the global supply system. We also quantify the effect of the 2008 financial crisis on the size and organisation of the trade system in Poland.
