Importance of Industrial Sectors within the Overall Economy — •Christian Hirtreiter1 and Johannes Josef Schneider2 — 1Faculty of Physics, University of Regensburg, 93040 Regensburg, Germany — 2Department of Physics, Mathematics, and Computer Science, Staudinger Weg 7, 55099 Mainz, Germany
We have a look at the overall economy of a state focussing on the exchange of goods and services between the various sectors of that economy. Depending on the market theory, either the best seller (the sector selling the largest value of goods and services to other sectors) or the best buyer (the sector buying the largest value of goods and services from other sectors) is the most important sector within the overall economy. We generate a sequence of sectors depending on their importance using the exchange matrix between these sectors. Furthermore, we show that this problem is an extreme case of the Traveling Salesman Problem with Clustering, which was recently introduced by us [1].
