4.1. Internal integration
The cluster analysis has revealed that, according to the internal integration stage
achieved, there are three different groups of companies in the Spanish food sector (see
Figure 4). Cluster 1 is made of firms with a high level of internal integration in both
interfaces: Logistics-Marketing and Logistics-Production (being higher in this latter
interface). In cluster 2 companies have a low level of internal integration in both
interfaces, while in cluster 3 firms have a low-medium level of integration in the
Logistics-Marketing interface while a medium-high level of integration in the Logistics-
Production interface.
