The automotive industry is changing with time.

Individual key database descriptions: The inventory price of an auto part at the time of billing is the weighted average price of the existing stock and the incoming stock, which is floating; the arrival of the accessory at the same time into the billing counter, warehouse account and warehouse physical account, And form input tax, the number of the above three database accounts should be the same when the warehouse.

Relative to the automotive service industry, the automobile manufacturing area and spatial organization have received more attention. Many geographers at home and abroad have explained the spatial process of the development of automotive manufacturing and the automobile manufacturing cluster. The research on the automotive service industry mainly focuses on the business model and the development of the automotive industry. The results of systematic research from the perspective of space are relatively few. Geographers have begun to pay attention to the spatial issues in the layout of the automotive service industry, summarizing the spatial layout patterns of the “point-axis” model, “point-to-face” model, and “point-axis-plane” three types of urban auto service industry. In general, although the automobile service industry space has become an important part of the urban space, the theoretical results have limited guidance for the layout of the automotive service industry. Therefore, this paper uses Nanjing as a case to study the spatial agglomeration and layout characteristics of automobile service industry. This will not only be beneficial to enrich the existing research results on the spatial layout model of urban service industry, but also provide reference and reference for the spatial layout optimization of automobile service industry.

Since the 1990s, with the growth of the urban economy and the increase in the number of residents' automobiles, the automobile service industry in Nanjing has experienced rapid development. The automobile sales, automobile maintenance, automotive supplies, car rental, and automobile culture have formed. The automotive service system.
