经济效益是评价科研、生产以及其它各项工作的重要指标之一。由于与经济效益相关的因素很多,各因素间又相互交错,因而要对其全部社会效果和效益给以定量的描述是很困难的。本文试就日常所见的经济效益计算问题,谈谈个人的一些粗浅看法,希望同志们批评指正。 Economic efficiency is one of the important indicators for evaluating scientific research, production, and other work. Since there are a lot of factors related to economic benefits, and the factors are intertwined, it is difficult to give a quantitative description of all social effects and benefits. In this article, I will discuss some of the individual’s superficial views on the calculation of economic benefits that I see in everyday life. I hope that the comrades will criticize and correct me.
