Abstract:
The spatial distribution of producer services in metro station areas in Xi′an city and corresponding acting mechanisms are studied through the effective description function of point of interest (POI) data to economic activities at small spatial scale. The scope determining method of a metro station area is put forward and the producer services sectors thriving within inner city are integrated into 6 categories of businesses. Then the general characteristics of spatial distribution of each category are analyzed and compared by location quotient calculation, as well as the local ones at the same time. Moreover, secondorder partial correlation analysis is employed to explain the influences on spatial distribution concentrations of 6 categories in metro station areas due to their material space environments, while some mechanisms can be concluded later with the spatial distribution outcomes of Xi′an city. The results indicate that the general distribution characteristics in the whole city is more concentrations of producer services happened in metro station areas than other places and there are still 3 patterns of local distribution characteristics for 6 categories of businesses, including centripetal ones, centrifugal ones and sandwich ones. The diversity increasing of space for residence and employment in metro station areas surely contributes to the spatial concentrating of most categories of producer services, but more open space makes obstacles to their concentrating in the same situation. Furthermore, the increasing of urban road density of traffic space in metro station areas only influences the distributing of a few categories and the influential effects are also weak.Three influential mechanisms of spatial distribution for producer services in metro station areas of Xi′an city can be put forward, including complementary mechanism owing to intensive entityrelationship among correlative industries, competitive mechanism owing to resources contention of material space, selective supporting mechanism owing to atypical demands from specific industrial sectors.
