In Chinese culture, particularly in business and bureaucracy, there is a strong emphasis on formality and procedure. 开设 (kāishè) fits perfectly within this context. It's the word you use when an action has official recognition and follows a set process. This contrasts with the Western, particularly American, “startup” culture, which might use more casual language like “launching” or “kicking off” a project. While you can “start” a business in a garage in the US, in China, the process of formally 开设公司 (kāishè gōngsī) involves official registration and documentation. The word itself reflects a mindset where legitimacy and formal establishment are highly valued. It signifies that an entity is not just a fleeting idea but a properly constituted operation.
开设 (kāishè) is prevalent in formal written and spoken Chinese, especially in news, business, and academic settings. You will rarely hear it used for everyday, casual actions.
The most common point of confusion for learners is the difference between 开设 (kāishè) and the more general verb 开 (kāi).
