摘　　要：经济学均衡包括交点均衡、驻点均衡和相切均衡。局部均衡都为交点均衡,一般均衡都为相切均衡。国际贸易理论研究一般均衡,所以国际贸易均衡大多为相切均衡。可以运用平面几何方法和立体几何方法理解国际贸易均衡,但立体几何方法更具有动感。考察国际贸易均衡的最佳方法是数学的"目标函数约束条件"方法。运用图形法和数学法理解国际贸易均衡时,应注重思考它们的经济学含义。Economic equilibrium includes intersection equilibrium,stagnation point equilibrium and tangent equilibrium. The partial equilibrium is intersection equilibrium,and the general equilibrium is tangent equilibrium. The general equilibrium is studied in international trade theory,so most of international trade equilibrium is the tangent equilibrium. International trade equilibrium can be understood through applying the methods of plane geometry and solid geometry,in which solid geometry method is more dynamic. The best method of investigating international trade equilibrium is the ＂objective function-constraints＂method of mathematics. When understanding international trade equilibrium by applying graphical method and mathematics method,the economic meanings of them should be paid special attention.
