An increasingly popular approach to protected areas as places that should combine natural and socioeconomic goals, poses questions regarding the effects of achieving such goals, particularly in the context of generating local economic benefits. Therefore, the objectives of this study are as follows: (1) determining the level and diversity of the socioeconomic development of communes with national parks as compared with neighboring communes that are not protected because of national parks (treating them as a point of reference for comparisons), and (2) presenting the level of tourism development in communes with national parks as compared with neighboring areas and other components of socioeconomic development. The achievement of the research objectives is based on the use of 28 indicators which, following the standardization process, allow for constructing a synthetic index (Composite Development Index-CDI) that shows development disparities in the two analyzed groups of communes. The results indicate that communes with national parks are characterized by a slightly higher level of general development as compared with other communes and a considerably higher level of tourism development. However, it should be noted that the adopted indicators differ considerably in both groups of communes.
