英美熱詞：planned obsolescence 計劃性淘汰

Planned obsolescence or built-in obsolescence in industrial design and economics is a policy of planning or designing a product with an artificially limited useful life, so it will become obsolete, that is, unfashionable or no longer functional after a certain period of time.

工業設計和經濟學中所謂的“計劃性淘汰”或“內置報廢”指在設計產品時人為地設定使用壽命，這樣產品在過了一段時間以后就會過時或者不好用。

The rationale behind the strategy is to generate long-term sales volume by reducing the time between repeat purchases.

這種策略背后的理念是通過縮短重復購買周期來促進長期銷售額。
