Solution
- Wrong. While some might see perfect competition as merely a theoretical construct, it indeed manifests in real-world settings.
- Wrong. It's a misconception to say that industries under perfect competition will perish due to insufficient profits. In fact, numerous enterprises thrive despite the challenges of perfect competition.
- Right. Within perfect competition, the earnings adhere to the rate of return that entrepreneurs must offer to secure capital from investors, often termed as the normal profit or the capital rental cost.
•
A错误。虽然有些人可能认为完全竞争只是一种理论结构，但它确实在现实世界中表现出来。
B错误。说完全竞争下的产业会因为利润不足而消亡，这是一种误解。事实上，尽管面临完全竞争的挑战，许多企业仍能茁壮成长。
C正确。在完全竞争中，收益需与企业家为从投资者那里获得资金而必须提供的回报率相一致，通常称为正常利润或资本租金成本。
可以解释下c 并且c是只针对perfect competition么 还是其他情况也适用呢
