✔ 最佳答案
需求改變與需求量改變的不同之處:
- Change in Demand需求改變
Caused by the change in factor other than price of a good由價格以外因素改變所引致
Lead to the shift of the whole demand curve整條需求曲線移動(D↑right右; D↓left左)
- Change in Quantity Demanded 需求量(Qd)改變
Caused by the change in the price of a good由價格因素改變所引致
Lead to the movement along the demand curve沿需求曲線移動

需 求 量 改 變 係因為價錢改變
[如果價錢上升,需 求 量就會下跌
如果價錢下降,需 求 量就會上升]
以上係叫Law of Demand :)
希望幫到你
