Abstract:

This paper studies the spatial pattern of intra-sectoral and inter-sectoral industries in Guangzhou metropolitan area using the digital city data of 2004. The industries of Guangzhou metropolitan area are classified as manufacture, wholesale and transportation, retail, producer service, real estate, administration service, education, health care and social assitance, entertainment and accommodation. The cartographic map of 1km2, percentage and location quotient are applied to study spatial distribution of establishments. In the central urban areas, administration service, real estate, retail, finance and insurance are the major industries while manufacture, wholesale and transportation and producer service are the major industries in the new cities. Average nearest neighbor distance (R) is used to study the intrasectoral spatial pattern. The establishments of Guangzhou are cluster distributed and finance and insurance are concentrated in central urban areas. Proximity index (PI) is used to study intersectoral pattern. The proximity of entertainment and accommodation and retail, education and health care and social assistance, producer service and administration service are more obvious.

Key words: average nearest neighbor distance, Guangzhou metropolitan area, industrial spatial pattern, location quotient, proximity index
