Identifying industries that operate with little global competition can be complex as there are rarely any industries completely devoid of competition. However, some industries may have characteristics that make global competition relatively limited. It's important to note that the competitive landscape of industries can change over time due to various factors.

1. Utilities: Industries dealing with essential services like water, electricity, and gas tend to have limited global competition. This is often due to factors such as high infrastructure costs, regulatory barriers, and the need for localized operations. Utilities often enjoy certain legal protections and monopolistic rights granted by governments to ensure uninterrupted service provision.

2. Telecommunications: The telecommunications industry can have limited global competition due to significant infrastructure investments required to establish networks. Companies in this industry often enjoy exclusive licensing agreements, spectrum rights, and regulations that may restrict foreign market entry. However, advancements in technology and deregulation efforts have increased competition in this sector in recent years.

3. Defense and Aerospace: Defense and aerospace industries typically have a high level of inherent immunity due to national security concerns. Governments often place strict regulations, export controls, and limitations on foreign ownership to protect these industries. As a result, global competition is somewhat limited, and domestic companies may enjoy advantages in securing contracts.

4. Government services: Industries that primarily serve governments, such as public administration, tax collection, or certain security services, may operate with minimal global competition. These services are often heavily regulated or outsourced to domestic providers due to sovereignty and security reasons. However, in certain cases, international companies may still compete for government contracts.

It's essential to remember that while these industries may have characteristics that limit global competition, competition within these sectors can still exist at a national or regional level. Furthermore, these dynamics can change over time as technology advances, regulations evolve, and market conditions shift.
