The article presents the achievements of the “Diagnosis of the state of Poland’s spatial economy”, developed in 1981–1983, which critically analyses the effects of the thirty-year impact of the principles of building socialism on Poland’s spatial economy. These effects are related to the elements of the current state of the country’s spatial management, which leads to the conclusion that many of the unfavourable phenomena and processes of that time also occur today, after 30 years of market economy and the democratic system. The article ends with a proposal of research on the contemporary spatial conditions of the country’s development.
