The Italian experience was also mentioned as a pioneer in this field. We concluded on the one hand that industrial clusters have an impact on the macroeconomy, in particular on economic growth by creating added value and increasing employment opportunities, and on the other hand an impact on microeconomics such as obtaining a competitive advantage based on innovation, reducing industrial costs, improving quality.enIndustrial Clusters; ItalyArticle
