Measuring the Knowledge Base of an Economy

* apologies for cross-postings

The interrelationships among technology, organization, and territory in
an economic system have been considered as a 'holy trinity' from the
perspective of regional development studies. The mutual information in
three dimensions was proposed as an indicator of the surplus value
(entropy) in triple-helix configurations. When this probabilistic
entropy is negative, the configuration reduces the uncertainty that
prevails at the systems level. Data about more than a million Dutch
companies were used for testing this indicator. This data contains
postal codes (geography), sector codes (proxy of technology), and firm
sizes in terms of number of employees (proxy of organization). The
knowledge base is mapped at three levels: national (NUTS-1), provincial
(NUTS-2), and regional (NUTS-3). The levels can be cross-tabled with the
knowledge-intensive sectors and services. The results suggest that
medium-tech sectors contribute to the knowledge base of an economy more
than high-tech ones. Knowledge-intensive services have an uncoupling
effect, but less so at the high-tech end of these services.
