Abstract
Spatial economic analysis, including research on regional development and competitiveness, has long been a high priority area in the social sciences, both domestically and globally. Several dominant international models relate changes in regional competitiveness to the volume of investment, physical capital and improvements in the income situation of citizens. This suggests that the promotion and implementation of investment has the greatest impact on regional development, as it generates technological innovation and innovation in order to raise the skills of the available labour force, employ human resources at higher wages and thus raise living standards. On the basis of these findings, our study examines the level of development of the domestic LAU1 districts on the basis of their complex (social, economic and infrastructural) level of development, their income situation and their economic competitiveness.
