Regions vary in economic growth, and the reason behind this has been a topic of interest. In the past, it was believed that technology was the main factor driving growth, but this view was criticized by economic geographers. They argued that some regions are better at developing and implementing innovations due to their specific characteristics and institutions. This led to the idea that regions play a crucial role in driving innovation and growth. Concepts like industrial districts, clusters, and regional innovation systems have been introduced to support this perspective.
