结合蔡昉对中国经济发展阶段的划分方法，分析了要素结构变化、矛盾冲突和农业机械化发展的特点及其发展阶段归因，研究得出：“马尔萨斯陷阱”阶段，农业劳动力“淤积”在农村，资本要素不足，农业机械化发展缓慢；刘易斯二元经济发展阶段，农业机械化水平随着要素流动半径加大而提高；刘易斯转折阶段，出现要素短缺，农业机械化发展速度减缓；新古典经济发展阶段，要素市场竞争促使农业机械化水平快速提高。因此，农业机械化发展出现减速是经济发展过程中的阶段性特征和必然结果，在这个连续谱全景图框架下，需要规范土地流转并实施土地改良工程，规范农机补贴流程，提高农机行业制造水平，加快农村三产融合发展实现农业机械现代化。

By using Cai Fang’s method of dividing China’s economic development stages, the changes of factor structure, conflicts of elements, characteristics of the development of agricultural mechanization and its developments stage attribution have been analyzed. The study shows that in the Malthusian trap development stage, large agricultural labor force silted up in the countryside; the capital element was insufficient; the agricultural mechanization developed very slowly. In Lewis dual economic development stage, the level of agricultural mechanization improved with the increase of factor flow radius. During the Lewis transition period, there was a shortage of elements and the development speed of agricultural mechanization slowed down. In neoclassical economic development stage, factor market competition spurred agricultural mechanization level to improve quickly. Therefore, the deceleration of development of agricultural mechanization is the periodic characteristic and the inevitable result in the process of economic development. As a result, in the framework of this continuous spectrum panorama, it is necessary to regulate the circulation of land, to carry out land improvement projects, to standardize the agricultural machinery subsidy process, to improve the level of agricultural machinery manufacturing, and to accelerate the integration of three industries development in rural areas so as to realize the modernization of agricultural machinery.
