本文根据辩证唯物主义的真理二重性原理，提出“第一生产力”的二重性观点，分析了“科学技术是第一生产力”这一命题的绝对涵义和相对涵义。其绝对涵义包括：时间上的超前性和先导性、转化上的加速性、作用上的协同性和爆发性；其相对涵义包括：时间上的局限性、程度上的近似性。由此，要求人们对科学技术、生产力范畴及其相互关系进行重新界定。 Based on the principle of duality of truth in dialectical materialism, this paper puts forward the dual view of “primary productive force” and analyzes the absolute meaning and relative meanings of the proposition that “science and technology are primary productive forces.” Its absolute meanings include: advance and precursor in time, acceleration in transformation, synergy and explosion in action; its relative meanings include: time limitation and degree of approximation. As a result, people are required to redefine the scope of science and technology, productivity and their mutual relations.
