The paper relates the results of the latest one of a series of municipal surveys concerning European funds’ influence on local development to economic and public opinion evaluations of the effects of EU policies in Poland. The research conducted in 2019–2020 and gathering the views of local governments is confronted with general economic and sociological evaluations in the field of the impact of EU funds in Poland. The study captured the perceived effects of two programming periods (2007–2020) as well as barriers and obstacles in their implementation at the local level. An ambiguity in perceiving supply-side effects still needs further studies, while the aspect of improving the quality of life is visible.
