生产工具不仅是生产力的重要因素，是生产力水平的重要标志，而且也是表明社会经济发展阶段的标志。马克思说：“各种经济时代的区别，不在于生产什么，而在于怎样生产，用什么劳动资料生产。劳动资料不仅是人类劳动力发展的测量器，而且是劳动借以进行的社会关系的指示器。” Production tools are not only an important factor of productivity, an important indicator of the level of productivity, but also a sign of the stage of social and economic development. Marx said: “The difference between the various economic times is not about what to produce, but about how to produce and what kind of labor information to produce. Labor information is not only a measure of the development of human labor but also an indicator of the social relations through which labor works. ”
