Business combinations are of the following types:
(i) Horizontal Combinations.
(ii) Vertical Combinations.
(iii) Lateral or Allied Combinations:
Lateral combination refers to the combination of those firms which manufacture different kinds of products; though they are allied in some way.
Lateral combination may be:
(a) Convergent lateral combination:
In convergent lateral combination, different industrial units which supply raw-materials to a major firm, combine together with the major firm. The best illustration is found in a printing press, which may combine with units engaged in supply of paper, ink, types, cardboard, printing machinery etc.
(b) Divergent lateral combination:
Divergent lateral integration takes place when a major firm supplies its product to other combing firms, which use it as their raw material. The best example of such combination may be found in a steel mill which supplies steel to a number of allied concerns for the manufacture of a variety of products like tubing, wires, nails, machinery, locomotives etc.
(iv) Diagonal (or Service) Combinations:
This type of combination takes place when a unit providing essential auxiliary goods / services to an industry is combined with a unit operating in the main line of production. Thus, if an industrial enterprise combines with a repairs workshop for maintaining tools and machines in good order; it will be effecting diagonal combination.
(v) Circular (or Mixed) Combinations:
When firms engaged in the manufacture of different types of products join together; it is known as circular or mixed combination. For example, if a sugar mill combines with a steel works and a cement factory; the result is a mixed combination.
Forms of Business Combinations:
By the phrase ‘forms of combinations’, we mean the degree of combination, among the combining business units.
