价格是总需求线的纵坐标吧？
NO.PZ2016010801000057 问题如下 “Shifts in the aggregate mancurve mcauseprichange, economic growth angovernment policies.” The statement is A.incorreabout prichange B.incorreabout government policies. C.incorreabout economic growth. A is correct.Prichange will not shift the aggregate mancurve. 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纵坐标，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。 影响A因素不是有stoprices anhousing prices吗？

incorreabout government policies. incorreabout economic growth. A is correct. Prichange will not shift the aggregate mancurve. 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。 请老师进一步下，为什么economic growth会导致A的shift呢
请问老师，economic growth指的是Y吗？为什么不是move along？
