A　nested　structure　is　a　structural　feature　that　is　conducive　to　system　stability　formed　by　the　coevolution　of　biological　species　in　mutualistic　ecosystems　The　coopetition　relationship　and　value　flow　between　industrial　sectors　in　the　global　value　chain　are　similar　to　the　mutualistic　ecosystem　in　nature.　That　is,　the　global　economic　system　is　always　changing　to　form　one　dynamic　equilibrium　after　another.　In　this　paper,　a　nestedness-based　analytical　framework　is　used　to　define　the　generalist　and　specialist　sectors　for　the　purpose　of　analyzing　the　changes　in　the　global　supply　pattern.　We　study　why　the　global　economic　system　can　reach　a　stable　equilibrium,　what　the　role　of　different　sectors　play　in　the　steady　status,　and　how　to　enhance　the　stability　of　the　global　economic　system.　In　detail,　the　domestic　trade　network,　export　trade　network　and　import　trade　network　of　each　country　are　extracted.　Then,　an　econometric　model　is　designed　to　analyze　how　the　microstructure　of　the　production　system　affects　a　country＇s　macroeconomic　performance.
