—Based on concepts of ecology modeling and specifi-4 cally on population biology, a methodology for describing a high-5 technology market’s dynamics is developed and presented. The6 importance of the aforementioned methodology is its capability7 to estimate and forecast the degree of competition, market equi-8 librium, and market concentration, the latter expressed by cor-9 responding market shares, in the high-technology environment.10 Evaluation of the presented methodology in the area of telecom-11 munications led to accurate results, as compared to historical data,12 in a specific case study. Apart from a very good estimation of the13 market’s behavior, this methodology presents a very good fore-14 casting ability, which can provide valuable inputs for managerial15 and regulatory decisions and strategic planning, to the players of16 a high-technology market, described by high entry barriers.17
