首先探讨金末金宋关系的发展脉络，即经历了破裂前的酝酿阶段、战争阶段、求和阶段、决裂阶段四个阶段：其次论述金末金宋关系的主流问题，赵永春先生认为金宋关系的主流是和平相处，我认为探讨金宋关系的主流问题应该分阶段进行具体分析，金末金宋的关系的主流是对立和战争，而不是和平共处：再次主要阐述金末对宋政策的评价，这里需要强调的是，传统史学观点认为金宣宗南迁汴京是弃城逃跑的懦夫行为，我认为面对中都残破的政治、经济、军事形势，以及蒙古大军持久的压力，金统治阶层选择迁都汴京是不得已而为之，也是在困境中寻找救亡图存的一条新路；最后阐述了蒙古、西夏对金宋关系的影响，特别是蒙古介入金宋关系，致使金宋战争不断，最终导致金朝灭亡。
