如何用“产品服务系统”（PSS）延长价值而非销量？
How can Product-Service Systems (PSS) extend value instead of sales volume?
PSS让企业卖“使用”而非“拥有”（如照明服务、轮胎按里程计费），厂商有动力做耐用、易修、可回收的产品，因为维修成本由其承担，从而脱钩增长与资源消耗。
PSS sells 'use' not 'ownership' (lighting-as-service, tires per km); makers gain incentive for durable, repairable, recyclable goods since they bear maintenance cost—decoupling growth from resource use.

什么是“计划报废”（planned obsolescence）？
What is planned obsolescence?
指厂商在设计时有意让产品更快损坏或落伍，促使用户频繁更换，从而扩大销量。它加剧资源消耗与电子废物，与循环经济相悖。
It means designing products to wear out or become outdated sooner, prompting frequent replacement and boosting sales. It worsens resource use and e-waste, opposing circularity.

为什么修好旧玩具比买新玩具更省地球？
Why is fixing an old toy better for Earth than buying new?
做新玩具要挖矿、用电、运很远；修一修就能继续玩，省材料又省能量，垃圾也变少。
Making a new toy needs mining, energy and long shipping; fixing lets you keep playing, saving materials and energy and making less trash.
