我做的是四大经济圈区域投资有效性的问题，四大经济圈总共包括17个省份城市，三个投入指标（x1,x2,x3）和2个产出指标(y1,y2)，我想从横向与纵向上进行分析，不知道是以年份还是省份来做DMU，在以省份做DMU的时候，出现了DMU Name is not for each DMU（there are at least 2 DMUS which share one name).if you are using panel data,you should choose Malmquist,Dynamic or Window model.
To run Malmquist, Dynamic or Window model, you need to upgrade to MaxDEA Pro.

请问这是怎么回事啊？求指点，谢谢！
