Cultural and Creative Industries (CCIs) have emerged as powerful drivers of regional development and revitalization in Europe in recent years. This study explores the impact of CCIs on European regions, focusing on their economic, social, and cultural contributions. Drawing on extensive literature review and empirical research, this study examines the role of CCIs in job creation, GDP growth, innovation, social cohesion, cultural identity, urban regeneration, and the revitalization of declining areas. Data were collected using questionnaires distributed to 345 key players in the Cultural and Creative Industry of Greece. The findings reveal that CCIs significantly enhance job opportunities in European regions, with 74.4% of participants acknowledging their role in reducing unemployment and underemployment. Moreover, 71.4% recognized the substantial contribution of CCIs to regional GDP, highlighting that their economic importance is comparable to traditional industries. CCIs are seen as catalysts for social cohesion and cultural identity, as 75.6% of respondents attested to their role in uniting diverse communities. These results emphasize the sensitivity of CCIs to the existing cultural and historical context of these areas. Furthermore, this study identifies outcomes of regional development and revitalization, including improved education facilities (21.7%), preservation of regional cultural heritage (14.6%), and enhanced business relations (26.7%). Regression analysis demonstrated a strong association between CCIs and regional development and revitalization. This study provides comprehensive insights into the contributions of CCIs to regional development and revitalization in Europe. Policymakers, practitioners, and stakeholders can use these findings to harness the full potential of CCIs for sustainable and inclusive regional development.
