Query: The Swedish System of Innovation: Regional Synergies in a
  Knowledge-Based Economy   Based on the complete set of firm data for Sweden (N = 1,187,421; November
2011), we analyze the mutual information among the geographical, technological,
and organizational distributions in terms of synergies at regional and national
levels. Mutual information in three dimensions can become negative and thus
indicate a net export of uncertainty by a system or, in other words, synergy in
how knowledge functions are distributed over the carriers. Aggregation at the
regional level (NUTS3) of the data organized at the municipal level (NUTS5)
shows that 48.5% of the regional synergy is provided by the three metropolitan
regions of Stockholm, Gothenburg, and Malm\"o/Lund. Sweden can be considered as
a centralized and hierarchically organized system. Our results accord with
other statistics, but this Triple Helix indicator measures synergy more
specifically and quantitatively. The analysis also provides us with validation
for using this measure in previous studies of more regionalized systems of
innovation (such as Hungary and Norway).
