就等于...
Reach for this when you want to spell out a logical consequence as an equivalence — 'doing X is equivalent to Y,' 'that's the same as Y.' It's the move that translates an action into its real-world meaning: 'continuing to invest in video is equivalent to handing over the battlefield.' Common in op-eds, business analysis, and arguments where you want to strip away the surface and show what something AMOUNTS to.

How to Think About It
等于 means 'equals.' Adding 就 ('then / exactly') tightens it into 'is exactly equivalent to.' The pattern flattens the moral or strategic distance between two acts: it claims they have the same effect, even if they look different on the surface. That's why it carries argumentative force — the speaker is asking you to accept the equivalence, often when it isn't immediately obvious.
Examples
放弃训练就等于放弃比赛。
Fàngqì xùnliàn jiù děngyú fàngqì bǐsài.
Giving up training is equivalent to giving up the competition.
现在退出，就等于把市场让给对手。
Xiànzài tuìchū, jiù děngyú bǎ shìchǎng ràng gěi duìshǒu.
Pulling out now is equivalent to handing the market over to competitors.

Common Mistake
Learners use 就等于 for simple math or literal equivalence, where 等于 alone is enough. 就等于 adds rhetorical force — it's for arguing 'X amounts to Y,' not for stating '2 + 2 = 4.' Using it for literal arithmetic sounds strange.

Don't Confuse With
等于
Plain 等于 = mathematical or literal equality. 就等于 = 'amounts to' — argues an equivalence in effect or meaning. Use 等于 for math, 就等于 for arguments.
就是说
就是说 = 'that is to say' — paraphrases. 就等于 = 'is equivalent to' — argues that two things have the same effect. Different rhetorical move.
意味着
意味着 = 'means / implies' — points to a consequence or implication. 就等于 makes a stronger claim of equivalence, not just implication.
