     Abstract: Based on statistical physics and graph theory, the research paradigm of a Complex Network, which has sprung up in the last decade, provides us with new global perspective to discuss the topic of international trade, especially agricultural commodity trade. In this paper, we engage in the issue of countries' positions in international agricultural commodity trade using the latest Complex Network theories. On a mid-level structure, countries are classified into three communities that reflect the structure of the "core/periphery" using the Weighted Extremal Optimisation algorithm and the Coarse Graining process. On a micro-level, countries' rankings are provided with the aid of network's node centralities, which presents world agricultural commodity trade as a closed, imbalanced, diversified and multi-polar development. Further, we at first time introduce the improved bootstrap percolation to simulate cascading influences following the breaking down of bilateral agricultural commodity trade relations.
