社会主义经济的本质特征之一,是以计划经济为主。经济有计划就是按比例发展。墙体材料的生产和发展,当然也有一个比例问题。作者在本文中提出,应当重视研究各类墙体材料产品之间,要有一个恰当的比例关系,科学地定量计算具体的比例,逐步形成有上海特色的墙体材料的比例构成。研究合理的比例关系,必须从现状、历史的实践经验和预测发展中寻找规律, One of the essential features of the socialist economy is the planned economy. The economic plan is to scale up. There is of course a proportional problem in the production and development of wall materials. In this paper, the author proposes that attention should be paid to the study of all kinds of wall material products. There must be a proper proportion relationship, scientifically quantitatively calculate specific proportions, and gradually form the proportion of wall materials with Shanghai characteristics. To study a reasonable proportional relationship, we must look for the law from the current situation, historical practical experience, and predictive development.
