宏观研究是微观研究的高度综合,两者不是相悖而是具有辩证的同一性关系,只是因为研究的目的、内容、范围和深度的不同而有所区分,宏观研究和微观研究都具有系统科学的特征,本文以机械工业为例进行探讨。 Macroscopic research is highly integrated in microscopic research. The two are not contrary to each other but have a dialectical identity relationship. They differ only in the purpose, content, scope, and depth of research. Both macro and micro studies are systematically scientific. Characteristics, this article takes the machinery industry as an example.
