The distance and retail store attraction have effect on consumer shopping action. Recently most relative quantitative modeling study on retail location did not simultaneously consider those factors including traffic network, traffic grade, store attraction and competition based on GIS. This paper aims at these shortages and attempt to integrate above factors and make quantitative analysis about large scale shops based on accessibility method, breaking point laws and GIS technique. The result indicates that accessibility of large scale supermarket in Shanghai central city is good, the west of city is better than east. Shops´ market region areas in near out ring are greater. Trade areas between inner loop and middle loop are smaller. Market size near out loop and inside inner loop is greater. Market scale of between inner loop and middle loop is smaller. This study can make urban planner know about retail network layout. Managers can quickly understand the shop trade areas and provide the consult for choosing shops location.
