The article presents the results of a questionnaire received in Autumn 2013 from over 1,300 Polish municipalities whose population does not exceed 50 thousand people. The material obtained from this questionnaire offers exact data concerning the performance of local governments in promoting local economic development, as well as opinions and values shared by these governments. The research is related to a similar undertaking performed in mid-1990s, and confirms earlier hypotheses indicating that spatial differentiation of performance of the local governments in Poland has deep historical roots.
