Shrinking World. The comparison of distance and entropy analysis. — •Janusz Miskiewicz1 and Marcel Ausloos2 — 1Institute of Theoretical Physics, University of Wroclaw, pl. M. Borna 9, 50-204 Wroclaw, Poland — 2S.U.P.R.A.T.E.C.S., B5 Sart Tilman, B-4000 Liège, Euroland
The analysis of similarities in development patterns of the leading world (mainly European) countries is performed. The economical situation of each considered country is described by its total GDP normalised to the GDP level of US dollar in 1999. For comparing cases, the yearly GDP increment time series are considered. The similarities between country developments are investigated by means of a statistical correlation distance and a distance based on Theil index, which could be considered as an entropy measure. The calculations are performed for a time window constant size, which is moving along the time axis. Next the time distance matrix is obtained and analysed by constructing two networks: the locally minimal spanning tree and the bidirectional minimal length path.
The time evolution of the mean distance between countries is investigated and the economy globalisation process thereby observed. The analysis is repeated for all possible time window sizes; a resonance time window size is then found; the latter could be interpreted as a globalisation time scale.
