问题如下：
“Shifts in the aggregate demand curve may be caused by price change, economic growth and government policies.” The statement is
选项：
A. incorrect about price change
B. incorrect about government policies.
C. incorrect about economic growth.
解释：
A is correct.
Price change will not shift the aggregate demand curve. It is the movement along the curve.
考点：总需求曲线
解析：价格本身是总需求曲线上的横坐标，所以价格的变动只会造成需求曲线上的点沿着曲线移动，而不会造成曲线的平移。
请老师进一步解释下，为什么economic growth会导致AD线的shift呢

价格是总需求线的纵坐标吧？
请问老师，economic growth指的是Y吗？为什么不是move along？
