Abstract

[fre] La plupart des mobiles usuellement avancés pour expliquer la diversification soulignent les avantages associés aux combinaisons d'activité, comme les synergies ou la réduction du risque, sans se référer aux caractéristiques propres aux activités de base et d'accueil. L'originalité de cette étude est de considérer la diversification comme un moyen de tirer parti de la variabilité des caractéristiques industrielles. Cette étude empirique compare donc diverses caractéristiques des activités de base et d'accueil des secteurs industriels diversifiés. Elle montre que la diversification n'est pas très liée aux disparités de rentabilité et de croissance entre les activités exercées, mais qu'elle dépend des structures de marché, la diversification étant orientée vers des activités plus concurrentielles que la base et croissant avec la concentration des activités exercées. [eng] Diversification is usually explained by advantages associated with combinations of activities, such as synergy or risk reduction, without reference to specific caracteristics of base and secondary industries. One can think of diversification as a way of taking advantage of the variability of industry caracteristics. This empirical study compares various caracteristics of the base and secondary industries of diversified industrial sectors. It shows that diversification is not very significantly related to their profitability and growth differences, but that it is related to differences in market structures, firms diversifying towards more competitive industries, but the extent of diversification growing with the concentration of base and secondary activities.
