> **Translation:** Shared Economy is an economic model centered on sharing and mutual assistance. It utilizes the internet, mobile applications, and other technologies to break down the traditional concept of ownership, allowing idle resources to be more widely shared and utilized. Shared Economy covers multiple areas, such as transportation (e.g., shared bicycles, ride-hailing services), accommodation (e.g., Airbnb), skills (e.g., tutoring, design), and more. Shared Economy models can usually effectively reduce costs, improve resource utilization efficiency, and promote community interaction, but they also come with challenges related to regulation, labor rights, and other issues.
