Retail Trade, General(零售贸易，综合)
The Retail Trade sector includes both (1) Store Reatilers and (2) Non-Store Retailers: 1. Store retailers operate fixed point-of-sale locations, located and designed to attract a high volume of walk-in customers. In general, retail stores have extensive displays of merchandise and use mass-media advertising to attract customers. They typically sell merchandise to the general public for personal or household consumption, but some also serve business and institutional clients. These include establishments, such as office supply stores, book stores, computer and software stores, building materials dealers, plumbing supply stores, and electrical supply stores. Catalog showrooms, gasoline services stations, and automotive parts stores are also treated as store retailers. 2. Nonstore retailers, like store retailers, are organized to serve the general public, but their retailing methods differ. The establishments of this type reach customers and market merchandise with methods such as the broadcasting of "infomercials," the broadcasting and publishing of direct-response advertising, the publishing of paper and electronic catalogs, door-to-door solicitation, in-home demonstration, selling from portable stalls (street vendors, except food), and distribution through vending machines. Establishments engaged in the direct sale (nonstore) of products, such as home heating oil dealers and home delivery newspaper routes are included here. Not included in this sector are large distinct segments of the retail industry such as Automobile Dealers, Clothing & Department Stores and Grocery Stores. They are categorized separately because of their relative size and distinct methods of operation.
