FAN Xiaoxia;LIU Jingyu;Henan University College of Environment and Planning;Henan University Research Center of Region Development and Planning;  
The spatial-temporal characteristics of producer services in Henan province were studied from regional and industry perspectives,based on the principal component analysis,Krugman specialization index,spatial Gini coefficient and location quotient.The results show that:1From the regional perspective,using the principal component analysis,only the score of Zhengzhou has been on the rise and the change is very remarkable,while the changes of other cities are very little.The spatial distribution of producer services show a shape of"L ",and the agglomeration level of Zhengzhou is in the absolute advantage.Using Krugman specialization index,on the time dimension,the specialized degree of producer services is not high,and industrial structure has a tendency to dissimilation,but from the angle of space,it do not make sense.2From the industry perspective,except scientific research,technical services,geological prospecting industry,whole sale and retail trade the agglomeration level of the other sub-sectors and the whole producer services approximately shows the inverted"V" shape,but it is on the rise on the whole,and the agglomeration level of knowledge and capital-intensive industries is relatively high.In each provincially-administered city,the agglomeration level of each sub-sectors and the whole producer services is relatively stable,but that of some areas changes obviously.
