it is a wise choice and the only way for catering enterprises to grow bigger and stronger, or to grow bigger and stronger. To be bigger and stronger, we must implement the strategy of sustainable development and make efforts in the following five aspects: First, make use of capital market resources to be bigger and stronger. To make catering enterprises stronger and bigger and implement sustainable development needs strong capital strength as the backing. Since the development of individual and private economy, the development funds of many enterprises have been obtained by profit accumulation or shares of relatives and friends, so the development is not fast because of limited funds. Yangzhou catering enterprises can take the form of joint venture with listed companies or other companies with capital strength, or use the accumulated assets to mortgage loans from banks to solve the development funds, and consciously transition from the development of individual and family capital to the utilization of social capital. The capital expansion of well-known domestic catering groups is inseparable from the capital market. The second is to use information technology resources to implement three-dimensional marketing. The planning and implementation of brand marketing is an important measure for catering enterprises to strengthen and implement sustainable development, and its purpose is to enhance the visibility, credibility and convenience of ordering food among target customers. At the same time, it enables enterprises to keep abreast of the changes in the needs of target customers, innovate varieties and service methods in time, and adapt to new catering needs. Using information technology resources to implement three-dimensional marketing is an important means of marketing for catering enterprises in the future, and it is also a low-cost and efficient marketing means. The third is to establish multiple brands to segment market demand. With the development of urban economy and the promotion of culture, consumers' demand for catering industry is more and more subdivided, and different people and different consumption purposes will choose different catering brands to consume. Market segmentation is mainly guided by different catering brands. In developed countries, different catering consumption formats, different consumption grades, different ethnic and regional flavors have different brands. Consumers are reluctant to patronize unknown brands because they are not at ease. Investors are concerned about corporate brands, and restaurant brands are the basis for consumers to choose restaurants. The fourth is to implement centralized procurement and processing to reduce labor costs. In order to unify quality standards, reduce procurement costs and reduce processing labor costs, Yangzhou catering enterprises should attach great importance to the establishment of centralized procurement and central kitchen institutions. At present, there are many problems in centralized procurement and processing: first, there are too many human interference factors in choosing high-quality supply bases; The second is the lack of strict quality and safety inspection records for food raw materials; Thirdly, there is a contradiction between self-purchasing and processing and the specification requirements of dishes, which often leads to the phenomenon that many varieties are purchased and the number of each batch is small. All these need to be carefully studied and solved by enterprises. Fifth, cross-regional operation and expansion of overseas markets. The inevitable trend of catering enterprises to become stronger and bigger is to implement cross-regional operation and expand overseas markets, which is a new stage of enterprise development and will put forward many new requirements for enterprise brand building. Yangzhou catering enterprises should carefully choose joint ventures or partners, properly handle the relationship between the two parties, effectively strengthen the management of expatriate employees, and effectively establish their own brand quality control system.
