With the booming business of professional retailers and more and more new stores, the profitability of single stores needs to be improved. Category management is mainly carried out in supermarkets and hypermarkets. Many retailers benefit from category management, and professional retailers also hope to improve their business performance through category management. The competition in the same industry is fierce, the demand for refined management is increasing, and the number of stores is increasing, resulting in the demand for category management. In terms of products, professional retailers are faced with the status quo of short product life cycle, rapid change, numerous products, and many similar and similar products. How to manage categories is a problem. Category management can help professional retailers achieve the goal of customer-centered and rapid response. With consumers as the center, manufacturers, suppliers, retailers and distributors make joint efforts to establish a system with quick response ability based on consumer demand, create customer value, improve the operation efficiency of the whole supply chain, reduce system cost and improve each other's competitiveness. The accurate definition of basic data is the basis of category management and category analysis. The data available for analysis include price range, function, material, style, color, specification, size, etc. The division of core categories, conventional categories and popular categories can help enterprises concentrate on category management of suitable categories and commodities. The basis of category definition comes from four basic elements: retailer's positioning, consumer's purchase decision tree, category development trend and retailer's management demand. The definition of a category can be carried out according to the following four steps: first, consider and choose which goods in this category are composed of, whether they have high substitutability and high correlation recognized by consumers, and whether they will be restricted by operating conditions when placed in a category. Then, the same category needs to be further subdivided into defective category and essay category, and then describe the * * * nature of the category. Category description should pay attention to defining the boundaries and characteristics of categories. Easy to clearly define with other categories. Finally, the category structure diagram is established, and each category, defective category and subcategory is given a unique code that can be recognized by computer system and manpower, and the division of related information, tables and organizations is adjusted. Category roles are divided into four categories: target category, general category, seasonal category and convenience category. Category role is the soul of category management, and it is the retailer's decision on the role of a category in all categories in the store according to his own strategy and using certain methods and standards. The role of categories determines the priority and importance of different categories in the overall business of retailers, and determines the resource allocation between categories. The significance of commodity combination lies in improving the value of consumers' shopping and the competitiveness of retailers in commodity combination through the selection, optimization and differentiation of commodities. Too many homogeneous varieties will not only increase transportation and inventory costs, but also occupy considerable funds. Therefore, it is necessary to carry out effective commodity combination, including commodity combination screening analysis, commodity deletion, commodity retention, commodity addition, commodity list determination and commodity quantification. An effective commodity combination is not a project, but needs to be analyzed, adjusted and reviewed regularly according to the changes of category commodities and the progress of commodity review, and the commodity status should be updated in time after the commodity combination is confirmed for inventory processing. In terms of stores, in the face of many stores, small stores, scattered stores and great differences between stores and customers, professional retailers should carry out group management of stores. Store grouping management is conducive to improving the concentration of SKU, forming purchasing scale and improving management efficiency, studying the different characteristics of consumers and markets, making product mix more suitable for consumers' needs, and arranging marketing plans according to consumers' principles. IT is conducive to the operation of stores and the efficient introduction and replacement of new products, to the establishment of unified standards for newly opened stores in the future, to the establishment of SKU monitoring reports of IT systems, and to the implementation of new (efficient) procurement management models. Store group planning should first obtain relevant data, then investigate and obtain consumers and properties in the business circle of the planned target store, investigate and obtain the competitive environment of the planned target store, clarify the role of store group and category, and complete the written document of store group planning. Stores should carry out space management, and the scope of space management includes: the display position and correlation of categories at all levels in stores, the distribution of space resources of each category, the principle of category display, the unity and difference of space management in different stores, and the analysis of space efficiency. Space management includes store layout management and shelf space management. Shop layout management includes shop layout design method, shop dynamic line design, setting of entrance categories in the shop, whether the locations and connections of various categories in the shop are reasonable, and whether the overall space size and location of key categories, sub-categories and sub-categories of the shop and related display inventory are correct. Shelf space management includes whether the position of goods on the shelf is reasonable, whether the number of display surfaces of goods is reasonable, whether the inventory of goods in stores and shelves can meet the sales demand, whether the space occupied by different goods is in direct proportion to their comprehensive performance, how to adjust the position of goods according to analysis, whether there are better choices on shelf devices, and what aspects of shelf space can be optimized. The difficulty of professional retailers in category management lies in the lack of suppliers with category management ability. They should collect necessary information from manufacturers, raw material suppliers and foundries as much as possible, store sales information from franchisees, distributors and agents, better understand the changes and characteristics of consumers' needs in various places, collect data from third parties, conduct focus group studies regularly, and extract their opinions and suggestions in order to better keep in line with consumers and the market. Due to the characteristics of the industry, professional retailers generally have a wealth of membership data and information, which are very valuable resources. The sales of many professional retailers account for more than 50% of the total sales, and the proportion of members' consumption is higher in the sales of their own brand products. Paying attention to the consumption of members, especially VIP members, can help us understand the feedback of consumers, especially important target consumers, on corporate goods.
