notes寫 Increase in supply is represented by a shift of the
entire supply curve to the right
 

Increase in quantity supplied is represented by a movement along the
same supply curve



我想問點解 Increase in supply 有2條curve 而
Increase in quantity supplied 得1條curve ?

✔ 最佳答案
首先你要明白quantity supplied同supply既分別..
Qs升或跌係因為價錢而改變..
但係S升或跌就係other factors導致,一定唔會係price改變
簡單來講quantity supplied既改變係因為price改變
supply就係因為other factors改變

至於supply curve,
Qs無論升定跌都一定係同一條upward sloping到..
不過S改變就係shift去左手邊或右手邊.. 變為兩條supply curve

所有概念都是相輔相成的
已用左很長篇幅回答了

increase in supply is related to non-price changes

Increase in quantity supplied is related to non-price changes

請細心咀嚼
