The urban industry is embedded in the city area which has its unique location characteristics and spatial pattern. Based on the micro-data of Shanghai urban industry enterprises in 2008, with the methods of location quotient, hot spot analysis and proximity index analysis, the paper explores the spatial distribution and the agglomeration characteristics of urban industries, as well as the spatial proximity relations among various industries during the process of industrial suburbanization. Results show that: First of all, the location choice of urban industry enterprises in Shanghai has a dual directivity to both central city and suburban areas, the range of 10~20 kilometers from city center is the densest area of urban industries, and the overall spatial distribution of urban industries has obvious heterogeneous characteristics. Food processing, packaging and printing, manufacture of tourism crafts and manufacture of small-scale electronic information constitute comparative advantage industries of central city, manufacture of interior adornment composes the comparative advantage industry of suburbs, and clothing accessories industry and manufacture of makeup and washing supplies constitute comparative advantage industries of suburban regions. Secondly, all kinds of industrial parks including commercial buildings, urban industrial zones and industrial estates in the city have become the major carrier of spatial agglomeration, which present "crater" gathering morphology. There are also some differences among the inter-industry according to the pattern of spatial agglomeration. Thirdly, when it comes to the spatial proximity relations, aside from being affected by some factors including the local government development policies, economic history basis and traffic location, the layout between all urban industries shows the following characteristics: the proximity layout is based on the same factor inputs, productive correlation, common market and policy orientation while the weak proximity layout is based on the heterogeneous exclusivity and environmental requirements.

Key words: urban industry, spatial distribution, agglomeration, proximity, Shanghai
