在中亚考察时，侯杨方接触到大量东西方文明交融后产生的技术，这促使他形成自己的"技术地理学"研究视角， 相比之下，仅靠文献考证和史料爬梳的传统史学缺乏跨学科视角，有很大的局限。 研究明亡清兴历史时，"技术控"侯杨方尤其关注当时第三方留下的史料，包括朝鲜王朝的秘密情报记录、西方传 教士的书信和记载，他从中看到珍稀的细节，说明技术更新对历史改变的影响。 侯杨方也走过唐朝高仙芝远征怛罗斯时的行军线路，还实地考察了他战败后的撤退路线。千百年来，骑兵都是中 亚战场上的重要作战力量，1618年努尔哈赤率领满洲铁骑正式与明朝开战时，依靠的也是在东北亚恶劣环境下锻 炼出来的精锐骑兵力量。侯杨方的观点是：明朝亡于军事力量的差距。 "一个失去了自我更新能力的文明，无论曾经多么辉煌，都难逃衰落的命运；而一个充满活力、善于学习的新兴力 量，即使起点较低，也终将后来居上。这个规律不仅适用于明清之际，也适用于人类历史上的其他重大转折。"侯 杨方总结说。 侯杨方认为，明朝是唯一一个被最后一拨游猎民族灭亡的定居帝国，这证明明朝确实落后了。 在哈萨克草原上策马奔驰，风驰电掣的感觉可以让人理解游牧民族的世界观；在暴风雪中艰难前行，才能体会到 古人 ...
