The gentrification approach as an analytical tool in assessing the effects of participatory urban policy

The objective of the article is to present the assumptions of the gentrification approach, which allows one to assess the impact of public spatial actions undertaken by various actors in the process of social production of space. The study proposes a research methodology that distinguishes the social, economic and spatial dimensions of gentrification. The author makes use of source literature on the subject of gentrification and public policy theories as well as the results of the author’s gentrification research conducted in Warsaw, New York and Istanbul on examples of places that were planned using various types of participatory techniques. The study performs the operationalisation of the measurement of gentrification as a useful analytical tool in policy science.
