是时间序列。同时有多个省时才是面板数据

你确定吗？有人回答我说是面板数据，我不确定了

最好有在教计量的或是精通的人回答我一下，也谢谢其他回答我的人

Panel data is data from a (usually small) number of observations over time on a (usuallylarge) number of cross-sectional units like individuals, households, firms, orgovernments.

In a simple way, Panel data measurements = time series measurements + cross-sectional measurements.

是时间序列，你的截面只有一个
