ENThe main Lithuanian manufacturing industry clustering preconditions are related to productivity, innovation, and export development. In this research paper, it was found that the strength of cooperative relationships among cluster members, more favorable opportunities to access, and use of infrastructure of business and professional human resources are the major factors to form the preconditions chosen for developing a research model. Four hypotheses have been formulated, which aim to confirm or deny the formation of clustering economic preconditions for productivity, innovation, and export development. Along with the exploratory study, the arisen hypotheses verified that improvement of infrastructure of business and professional human resources and easier access to it for companies have a positive impact on export development. Two other factors the strength of cooperative relationships and the infrastructure of human resources are not significant. Cooperation and partnership processes remain undeveloped, as highquality and fullvalue formation of the economic preconditions for productivity, innovation, and export development is not ensured properly. Keywords: industrial clusters, economic preconditions, competitiveness, productivity, innovation, export. [From the publication]
