Measuring the knowledge base of an economy in terms of triple-helix relations among ‘technology, organization, and territory’

Can the knowledge base of an economy be measured? In this study, we combine the perspective of regional economics on the interrelationships among technology, organization, and territory with the triple-helix model, and offer the mutual information in three dimensions as an indicator of the configuration. 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 are used for testing the indicator. The data contain postal codes (geography), sector codes (proxy for technology), and firm sizes in terms of number of employees (proxy for organization). The configurations are mapped at three levels: national (NUTS-1), provincial (NUTS-2), and regional (NUTS-3). The levels are 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.     

Measuring the knowledge base of regional innovation systems in Germany in terms of a Triple Helix dynamics

The interaction among the three sub-dynamics of economic exchange, technological innovation, and institutional control can be captured with a generalized Triple Helix model. We propose to use the information contained in the configuration among the three sub-dynamics as an indicator of the synergy in a configuration. This measure indicates the reduction of the uncertainty which prevails at the level of an innovation system. On the basis of data at the district level in Germany, the conclusions of a previous study about the Netherlands are tested: medium-tech manufacturing is the main driver of the knowledge-based configuration in a regional economy, while knowledge-intensive services tend to uncouple the economy from the regional configuration. At the level of regions (NUTS-2) Germany's knowledge-based economy is no longer structured in terms of the previous East–West divide of the country, while this divide has prevailed at the level of the states (NUTS-1) that constitute the Federal Republic. However, the effects of high and medium-tech are not specific for the western or eastern parts of the country. The configuration of medium-tech manufacturing can be considered a better indicator of the knowledge-based economy than that of high-tech manufacturing.

Science policy in changing times: are governments poised to take full advantage of an institution in transition?

While it is widely acknowledged that the institution of science is currently undergoing a major transformation, there remains reluctance in many sectors to embrace the changes and maximize the utility of science and its role in economic growth. The transformation of science is driven by economic factors rather than those value-based. Accordingly, confusion and contradiction in science policy statements become apparent when the structure of science policy and the mechanisms that aim to support collaborative arrangements of science are examined. Historical and cognitive evidence shows the distinctions of “applied” and “basic” research are human constructions and, as such, have become a handicap to the emerging knowledge-based economy. It is concluded that, if the economic and social benefits of integrated arrangements in knowledge production are to be realized, there is a pressing need to modify the current institution of science and the policies that would underlie it.
