The study aims to develop a methodology for analyzing the trend of concentration of economic activities in the main core of national polycentric network A spatial projection has been realized in ArcGIS platform, for the period 2000-2012, containing the number of companies, number of employees, turnover and profit The original images were converted to images created 8-bit grayscale (using open-source software ImageJ) are then analyzed by Higuchi 1D Fractal Dimension algorithm using open-source software IQM Higuchi fractal dimension provided us very useful information about more or less chaotic disposed in space by the number of companies, the profit, the number of employees and the turnover From data analysis we observed a increase of Higuchi dimension with the growing economic influence of the main centers of development for all the four parameters We observed that Higuchi analysis could help in identifying of the increasing of the influence of the main centers on the neighbouring territories, in periods of economic development, or decreasing of influence in the periods of the economic crises For testing and confirmation of the veracity of Higuchi analysis the results obtained were confirmed by gray box-counting analysis using Fractal Analysis System and Fraclac/ImageJ Hence, the Higuchi's fractal dimension is a very good, fast and versatile method for modeling evolution of concentration trends in the national economy.
