14 CONCLUSIONS ON SEAPORT CLUSTERS<br />

In this chapter, relevant conclusions with regard to seaport clusters are drawn. <strong>The</strong>se<br />

conclusions are especially relevant for scholars with an interest in seaports. Six conclusions<br />

are discussed, and the chapter is finalized with suggestions for port research that builds on<br />

this research.<br />

14.1 <strong>Seaport</strong> clusters<br />

<strong>The</strong> application <strong>of</strong> the cluster concept has resulted in more clarity on clustering in seaports:<br />

• First, it has become clear that seaports are clusters. In all the three cases, the cluster<br />

consists <strong>of</strong> substantial numbers <strong>of</strong> firms, all related to the arrival <strong>of</strong> ships and goods in<br />

seaports. <strong>The</strong> majority <strong>of</strong> value added and employment in the three clusters in not<br />

generated in primary port activities (cargo handling), but in related activities, such as<br />

logistics, manufacturing and trade. All these activities are concentrated in seaports.<br />

• Second, it is possible to identify a port cluster region. In all three cases, port activities<br />

are distributed over a number <strong>of</strong> municipalities and not limited to the port city. In fact, in<br />

the LMPC and Rotterdam, the port-cities have a lower concentration <strong>of</strong> port activities<br />

than smaller municipalities in the vicinity <strong>of</strong> the port.<br />

• Third, a ‘general’ list <strong>of</strong> cluster activities can be compiled. Such a list consists <strong>of</strong> all firms<br />

active in cargo handling, transport and logistics, and manufacturing and trading firms in<br />

a small number <strong>of</strong> ‘chains’ such as chemicals and grain. In the empirical part the list <strong>of</strong><br />

cluster activities, each with the corresponding NAICS, are presented. This list <strong>of</strong> cluster<br />

activities is general and can be used to compare port clusters worldwide.<br />

14.2 Internal competition in seaports<br />

<strong>The</strong> lack <strong>of</strong> internal competition is a weakness for seaports, even if external competition is<br />

fierce enough to prevent firms from monopoly pricing, because internal competition fosters<br />

specialization and creates an innovation-prone environment. Internal competition in cargo<br />

handling segments such as dry bulk, containers and fruits, and in most nautical port
