44th Congress of the European Regional Science Association: "Regions and Fiscal Federalism", 25th - 29th August 2004, Porto, Portugal
In regional science the interest in spatial distribution of productivity is focussed on labour productivity. In our research we focus on another important production factor that is land. By planning local authorities allocate land to different categories of land use. As part of research on the efficiency of this allocation process in the Netherlands, a method is developed to determine the productivity of industrial land (added value per hectare industrial land). To calculate this ‘spatial productivity’, data from the Dutch industrial estates database are used in combination with regional employment and regional output statistics. The paper will explain the method used and show some results. The research outcomes show that there are substantial differences in spatial productivity in the Netherlands. These differences seem to correlate positively with the urban density. On the other hand the share of added value created on industrial estates by region seems to correlate negatively with urban density. Therefore there is some evidence for the hypothesis that industrial land in urbanised regions is used more efficiently than in other areas, indicating that agglomeration effects are observable in spatial productivity.
