ABSTRACT
the Cement industry is particularly suitable for the study of the relationships between the characteristics of an industry and its structure and organization. The product, if it has not always been homogeneous, can be closely defined, and it is sufficiently homogeneous for measurement by weight to be reliable. The number of firms in the industry has never been very great and relatively few have many outside interests; thus they can both be discussed individually, and grouped meaningfully in ways which make it possible to substantiate generalizations.
