Which industries operate almost devoid of global competition?

Industries that operate almost devoid of global competition often include those with strong regulatory frameworks, such as public utilities and certain government services. Additionally, niche markets like local artisanal products or services, where cultural, geographical, or legal barriers limit competition, can also fit this description. Furthermore, some healthcare sectors, particularly those reliant on local expertise or infrastructure, may experience limited global competition due to the specificity of their services.
