港航企业区位特征及其空间关联——以上海港口后勤区为例

The behavior space study on port enterprises is becoming a new hotspot in the modern port geography.Taking Shanghai port backup area as an example,we have established a spatial attribute database of port enterprises,collected enterprise data of manufacturing,ware-housing,commerce,commercial office industry in each county,and corresponding construction data.This study comprehensively applies spatial Gini coefficient,spatial statistics and interpolations in GIS,and coefficient of geographical linkage for medium-micro scale depiction of location characteristics and spatial correlation of major enterprises in Shanghai port backup area.The results show that the port enterprises of Shanghai has a wide distribution(city area),featured by spatial accumulation;different types of port enterprises have different location choices and enterprises take the city centre as the core,scattered along the Huangpu River most obviously while big non-vessel transportation enterprises scatter and small ones assemble;enterprise location choice is irrelevant to manufacturing industry in space while international container transportation enterprises have obvious regional dependence.
