市场经济 is a formal but widely understood term used across various domains.
In the News and Government: It's a staple in news reports, government documents, and official speeches when discussing economic policy, growth targets, or reforms.
In Business: Business leaders, economists, and entrepreneurs use it to discuss market conditions, competitive strategy, and investment opportunities.
In Daily Conversation: While less common in casual chat, people might refer to it when discussing broad trends like rising housing prices, the job market, or the intense pressure of competition. For example, someone might sigh and say, “这就是市场经济啊!” (This is the market economy for you!), to comment on fierce competition for a job.
Connotation: The term is generally neutral to positive, associated with progress, wealth, and opportunity. However, it can also carry negative connotations when discussing the “dark side” of development, such as the growing wealth gap, high pressure (内卷 - nèijuǎn), and environmental issues.
