Scale of production and choice of technique in the engineering industries in developing countries
研究了发展中国家三个工程行业（螺母螺栓、铸铁、机床）中产量规模与技术选择及成本的关系，发现成本随规模下降，资本产出比降低，劳动生产率提高。
This article examines the relationship between scale of production, optimal choice of technique and costs for three engineering industries: nuts and bolts, iron founding and machine tools. In all three industries costs of production fell as the scale of output increased. This was associated with switches of technique and the spread of fixed costs over a larger number of units. The capital‐output ratio fell and labour productivity increased with increases in scale while, in most cases, the capital‐labour ratio increased. The implications of these findings are briefly discussed.
