Resumen
This article is a continuation of the co-author's paper in the Scientific Papers of the University of Gdansk Economics of Transport and Logistics no. 61, In which exogenous factors (eng. contextual environment) of air transport development were analyzed. Comprehensive problem development requires two-dimensional analysis with a working environment. The study focused discussion on selected endogenous factors including: infrastructural and social, market, business and technical-technological. Due to the scale of the issue, issues of liberalization and deregulation of the sector have not been addressed, which also fall within the group of important endogenous factors influencing the development of air transport. In addition, they have been repeatedly presented in aviation studies.The aim of the discussion is to present the most important transformations of the contemporary aviation services market by the influence of endogenous factors. The main thesis of the study is that endoogenic development factors determine the development and transformation of modern air transport and its market.
