Implementation of industrial parks had become a worldwide trend in recent decades to promote economic growth and reducing social differences among the regions. However, worldwide examples show that many poor decisions were made in the planning stage. As a result, we have a lot of inefficiently working, obsolescence and even abandoned parks.  The purpose of this paper is to analyze the theoretical and applicable aspects of the rational planning of efficiency operating industrial parks. The authors presented the comparative analysis of two industrial parks in Tauragė region in term of efficiency. The results proved industrial parks demonstrate better performance (by the number of investors attracted to the park) and have to be developed near major cities to ensure the supply of labor force for developing industries.
