本文认为,中共中央将山西作为华北抗战战略支点的决策是土地革命战争后期东进战略方针的发展和具体体现,最早源于中央对长征落脚点及战略发展方向的探讨;未来对日作战的需要、军事地理和自然经济条件、红军作战需要足够的回旋空间等三个因素是向山西发展的东出战略形成的根本原因;“西安事变”和“卢沟桥事变”使红军东渡黄河实行战略展开成为可能;太原失守后共产党八路军成为山西敌后抗战主角,山西战略支点最终形成。 This paper argues that the decision of the CPC Central Committee to regard Shanxi as the pivot point of North China’s war of resistance against Japan was the development and concrete manifestation of the eastward strategic guideline of the latter part of the Agrarian Revolutionary War. It originated from the Central Government’s probe into the long march and the strategic development direction; , The three factors of the military geography and the natural and economic conditions, and the need for the Red Army to exercise sufficient space for maneuvering are the fundamental reasons for the formation of the eastward strategy for the development of Shanxi. The “Xi’an Incident” and the “Lugouqiao Incident” have caused the Red Army to go eastward to the Yellow River It is possible to carry out the strategy. After the fall of Taiyuan, the Eighth Route Army of the Communist Party became the protagonist of the anti-Japanese war in Shanxi and the strategic pivot of Shanxi finally formed.
