The Flemish maritime ports play a major role in the Belgian economy, not only in terms of the industries they encompass but also as intermodal centres where transhipment activities are concentrated. This update1 paper provides an extensive overview of the economic importance and development of the Flemish maritime ports, through revised results for the period 1997 - 2003.

In addition, it includes figures with respect to the ongoing growth of several cargo traffic segments and provides an overall picture of social developments in the Flemish maritime ports.

The indirect effects were estimated on the basis of data from the National Accounts Institute. In the Flemish maritime ports, direct VA came to almost 11.5 billion euro and total VA - the sum of direct and indirect VA - to 22 billion euro in 2003. In the same year direct and total employment reached respectively 105,000 and 239,000 full-time equivalents, while direct investment reached 2.5 billion euro.
