通过对弧后盆地大地构造体制的讨论，作者认为其属活化作用的产物。根据地质、地球物理、地球化学等资料的分析，作者得出结论认为，由于东亚岛弧系岩石圈的均衡作用及海沟外侧冷却大洋岩石圈块体的下沉拖曳牵引等作用，使软流圈在岛弧系下方发生分异，这种分异作用带动东亚陆缘向东扩张，从而产生弧后的张开。文中还对其它模式做了概略的讨论。最后，作者将弧后盆地分为五个演化阶段，并对各阶段特征做了简述。
By discussing the tectonic system of the backarc basin, the authors consider it to be a product of activation. Based on the analysis of geological, geophysical and geochemical data, the authors concluded that due to the balance of the East Asian island arc lithosphere and the sinking and dragging of the lithospheric block outside the trench cooling the asthenosphere Differentiation occurs under the arc of the island system. This differentiation causes the East Asian continental margin to expand eastwards, resulting in a back arc. The article also made a rough discussion of other modes. Finally, the author divides the backarc basin into five stages of evolution, and gives a brief description of the characteristics of each stage.
