我国农业机械化发展的阶段性

论述了农业机械化分阶段发展的理论依据，从农业机械的替代效应，农用总动力结构变化，人畜机作业费用构成，农业劳动生产率的变化等４个方面分析了我国农业机械化的现状，得出我国农业机械化仍处于初步机械化阶段的结论，提出应根据分类指导，重点突破的原则，制定相应的农业机械化区划和经济区划，并在农业机械化区划的基础上，结合新情况，拟定不同地区的农业机械化实施方案。

Stages of Development of Agricultural Mechanization in China

The theoretical basis of stage-level development of agricultural mechanization is described. The current status of agricultural mechanization in China is analysed based on the substitute-effect of agricultural machinery, structural adjustment of agricultural total power, composition of work charge on human-animals-machinery and of agricultural labour productivity. It was found that agricultural mechanization in China is still on the preliminary stage. Making division into districts of agricultural mechanization and economy according to the principles of classification guiding and key breaking-through, as well as the new implementing project of agricultural mechanization for different regions are put forward.
