以城市群为空间层次，通过比较劳动生产率和产业结构偏离份额的对比，采用GIS空间分析滇中城市群产业结构效益为：2002—2011年产业结构层次较低，结构效益较差，产业结构阻碍滇中经济的发展速度；产业结构逐渐趋于合理化，对经济阻碍逐年下降。%The paper takes the urban agglomeration as a spatial hierarchy and uses the contrastive anal-ysis of comparative labor productivity and deviation of industrial structure as well as the spatial analysis technique of GIS to analyze the industrial structure benefit of urban agglomeration of Central Yunan. The conclusion is that urban agglomeration area’s industrial structure is at a low level from 2002 to 2011, which has hindered the economic growth. However, the industrial structure tends to be in a reasonable state and its negative effects on economic growth are declining year by year.
