This edited volume analyses and discusses the systematisation of Polish socio-economic transformations of the last three decades using selected examples of the most important changes. 1989 marked the onset of the political transformation process in Poland and other countries of Central and Eastern Europe. The transition involved a shift from a socialist system to a parliamentary democracy and from a command economy to a market one. Due to the deep economic crisis that culminated in 1988 and the peaceful model of change developed and implemented in Poland, the magnitude and manner of implementing various initiatives was unprecedented and had specific implications. This transformation opened Polish society and the Polish economy to the impact of global social and economic changes, triggering successive transformations, often overlapping in terms of their causes and consequences. This publication aims to present the course and effects, in particular territorial, of Poland's socio-economic transformation in the years 1990–2020. The analysis covers the key aspects of this transformation, illustrated with references to the concepts and theories of development, domestic and foreign literature, own empirical research and existing or newly developed model approaches to transformation in the territorial dimension. The book appeals to researchers and student in the fields of geography, spatial management, economics and business, sociology and political sciences, public and private economic research institutes, employees of governmental bodies and corporations, consultants in public administration, journalists and policymakers.
