This master’s thesis took a deeper insight into analysis of global telecommunication sector strategic alliance activities during years 2000-2010. The main objective of this thesis was to study the quantitative effect of macroeconomic and company specific uncertainty upon strategic alliance structure, form and its partner’s geographical positions. In addition to it uncertainty influence on amount of strategic alliances and participating partners has been studied. Empirical part of master’s thesis used secondary data obtained from SDC Platinum and Thomson Datastream – databases. 50 world’s biggest telecommunication companies from different countries were involved into final data. Statistical analysis was conducted using logistic and panel data regressions. Only two hypotheses out of five, proposed in thesis, were partly supported. These particular hypotheses assumed a negative effect of growing uncertainty upon vertical and domestic alliances probability. The rest of regression equations produced contradictory and statistically insignificant results.
