These are times of transition. In this era of rising international tensions, special autonomy and decentralization are increasingly valuable. Local leaders require new strategies to improve the quality of life for residents and grow region-based industries across borders. South Tyrol, Italy was designated as a special autonomous province in 1992, particularly. The Sud Tyrol Province has excelled in 19 areas. These include addressing the climate crisis, promoting renewable energy, protecting the Alpine forest environment, managing mountain disasters, and fostering immigration and diversity. Additionally, the province boasts a thriving high-tech industry and regional development. This is comparable to the Jeju Self-Governing Province, which also strives for a high degree of autonomy. These two regional governments share a similar history, natural and human environment, and a desire for greater autonomy. We will discuss the direction of development, such as the expansion of autonomy in special autonomy by looking at the success stories of domestic special autonomy and South Tyrol together.
