STUDY ON AFRICAN ECONOMY STRUCTURE BASED ON SPATIAL AUTOCORRELATION
收集1990-2000年非洲经济发展数据，用平均方差权重法计算经济综合指数，通过空间自相关分析揭示非洲经济空间异质性明显、集聚性弱，并划分六类发展模式。
In this paper,the economic development data of Africa in 1990-2000 were collected,10 representative indexes were selected,weights of indexes were calculated used the average-variance-weight method,the economic comprehensive index of African countries was calculated,and the character and rule of economic structure was analyzed at the base of the spatial autocorrelation method.The results showed that: ①the value of Moran's I was 0.0214,which means that African economy presents infirm positive spatial autocorrelation,in Africa,the region economy centralization and economy area was not existing,while the spatial heterogeneity was obvious;②based on the economy index and local Moran's I,the development pattern could be classified six classes and used hierarchical cluster analysis method;③the influence of factors in Africa economy were analyzed,e.g.mineral resourse abundance,location of countries,society and history factors.There were main factors.
