<strong>The</strong>se figures show that the LMPC has lost market share, especially in container throughput.<br />

This is explained to some extent by natural factors, and also because <strong>of</strong> the LMPC’s<br />

weaknesses, most importantly its lacking capability to solve collective action problems and<br />

develop an adequate system for handling containers and moving them into the hinterland.<br />

Apart from containers (the only growth market), the LMPC has not lost market share,<br />

predominantly because it can operate at low costs (land prices are low and internal<br />

competition secures low handling rates) and does not face congestion problems.<br />

Another indicator <strong>of</strong> the performance <strong>of</strong> the LMPC is the relative concentration <strong>of</strong> various<br />

cluster activities. ‘Support activities for water transportation’, the ‘core’ <strong>of</strong> a port cluster, are<br />

strongly concentrated in the LMPC. <strong>The</strong>se firms have to be located at deepwater facilities.<br />

Activities that can locate in seaports, such as logistics consultants and transportation<br />

arrangement firms are less concentrated in the LMPC. This indicates that the cluster does<br />

not attract a large share <strong>of</strong> footloose port related activities. This can be explained by its<br />

weaknesses: the cluster is not diverse and customers and suppliers are absent in the<br />

LMPC.
