The Role of Geographic and Sectoral Diversification, and the Herfindahl-Hirschman Index: Insights from Italian Provinces and Regions
Year: 2024
Type: article
Abstract: This study examines the role of the Herfindahl-Hirschman Index (HHI) and a new diversification index that integrates geographical and sectoral factors to analyze economic activities in Italian provinces. The research highlights how local territorial heterogeneity influences urban and regional economics, emphasizing diversification as a strategy for growth. The findings underscore diversification’s importance in enhancing economic stability and resilience, while comparing it with specialization. Although it can boost competitive advantage through efficiency and innovation, specialization also increases vulnerability to sector-specific risks. The study calculates the HHI by using three categories: geographical diversification of export destinations, sectoral exports, and geographical import diversification. These insights provide a groundbreaking understanding of the economic dynamics within Italian provinces and regions, showcasing the advantages and trade-offs between diversification and specialization in regional economic development.
