LLU) within the doctoral study programme Agrarian and Regional Economics, sub-branch of science-Regional Economics.The hypothesis of the doctoral dissertation: Regional clusters in Latvia are emerging in region-specific industries and are with high development potential.The overall aim of the doctoral dissertation: to identify regional clusters and to determine its potential in regions of Latvia.The following specific research tasks are set up to achieve the aim: 1) to examine theoretical, historical and documentary aspects of regional clusters, including regional clusters' effect on regional growth and development, 2) to determine and analyse preconditions for the establishment and growth of regional clusters in regions of Latvia, 3) to identify regional clusters in statistical regions in Latvia, approbating developed regional cluster identification methodology, 4) to elaborate potential of regional cluster establishment and development potential in the food manufacturing industry in Latvia. The doctoral dissertation is structured according to the hypothesis, aim and tasks and consists of four chapters.Chapter 1 describes theoretical, historical and documentary aspects of regional clusters and develops a framework for regional cluster and regions' economy interactions. It is found that cluster establishment has a positive effect on businesses, its survival rate and growth that lead to regional growth and development.Chapter 2 examines the preconditions for the establishment and development of regional clusters, including aspects like historical development of entrepreneurship, business environment, social and economic differences of the regions. It is found that Riga is a cluster development centre with high social and economic activity rate, while in other regions cluster development is important to decrease the gap between social and economic differences. The industries forming the cluster's core are identified.Chapter 3 performs identification of the regional cluster potential. Initial identification is performed in cluster core industries using the adjusted cluster mapping methodology that identified regional specific clusters in which development is influenced by existing infrastructure, historical development of industries and the existence of large enterprise in the region. In-depth identification is performed using mapping methodology and indexes that allow identifying clusters in the food manufacturing industry in regions depending on the availably of natural resources.Chapter 4 examines regional cluster potential in the food manufacturing industry in Latvia. Theoretical cluster models are developed and fish production and processing cluster's stage of development and potential are determined. Potential cluster development scenarios show high potential to form cluster in the fish processing industry with the initiative of association.The main conclusions, problems, and solutions are presented at the end of the dissertation.The size of the dissertation is 174 pages, including 34 tables and 42 figures.
