1. Introduction

Shared economy is a new economic form based on the rapid development of the Internet, which has changed the traditional mode of resource using and business model. Through the sharing of surplus assets between people, the idle resources will be used, so as to enhance economic and social benefits, and thus to reconstruct social relations and innovate social system. At present, the shared economy is developing and permeating all walks of life, and has rapidly risen to become the new kinetic energy of leveraging economic and social development. The popularization of open data and mobile Internet provides technical conditions for optimizing the allocation of resources on the shared economic platform. Hunger breeds discontentment; shared economy has very big development space in the catering industry; catering enterprises generally existing information management lags behind, is still difficult to supply chain resources integration and optimization, which caused the restaurants’ human technology, food and space resources to waste. And people have higher requirements for dining environment, experience and other aspects. The fierce competition in the catering market will require the catering enterprises to continuously refine the management technology, accumulate the brand value, integrate the resources, and expand the financing channels [1] . The rapid development of various catering O2O platform models is needed in order to overcome the shortcomings of the traditional restaurant management [2] . The general catering O2O platform can only achieve online payment and restaurant consumption [3] . They can’t share the resources of restaurants, chefs, ingredients, recipes, and can’t provide users with a comprehensive daily food and beverage record and provide personalized management and guidance according to the nutritional and healthy status of users, so the stickiness of the system is not enough and it is difficult to analyze and make decisions on the catering of the users [4] [5] . This paper integrates the idea of “shared economy”, proposes a shared restaurant business model, and uses cloud computing to integrate and share software and hardware resources and information to build a cloud platform for shared restaurants.

2.1. Operating Model of Shared Restaurant

The shared restaurant is joined by a large number of high-end restaurants, campus restaurants, etc., With such restaurants attendance are not high, use the idle space in the restaurant, through the shared platform to integrate the real-time and available resource supply information and demand information of consumer meal, through the big data algorithm accurate matching and connection, achieve mutual benefit between supply side and demand side. Provide shared restaurant brands for franchised restaurants, and provide safe, convenient and affordable catering services for consumers, and create high quality and healthy brand reputation.

Shared restaurant’s business and consumer resource information integration is in the shared platform to complete. Franchise restaurant need to upload recipes to the merchant version platform, and to update the available table number and seat, as well as for the sharing of ingredients and other information on the platform. Consumers recharge the platform to become members, and can enjoy coupons and member points and other preferential, and through the platform to settle the payment of meal costs. Members input the filter condition on the platform according to the meal demand, such as meal time, number of people, price, taste and other information. Franchise restaurant to look over real-time sharing of ingredients, chefs and other resources on merchant version platform, and buy the rest of the restaurant’s leftover ingredients, or rent the chef shared by the shared platform.

The shared restaurant is mainly divided into three different forms, the high-end restaurants, the campus restaurants and the internal guest experience stores, as shown in Figure 1. The high-end restaurants have comfortable restaurant environment, high level of chefs, but because of the high price, there are a lot of idle resources in the restaurant. Members invest in a high-end restaurant, and become a shared restaurant partner, can participate in the management of this high-end restaurant, and share the operating profit of the restaurant. The campus restaurants are usually invested by universities. The restaurants are strictly supervised by food safety, but their professional level and energy consumption are not high, and the tastes are often not as good as the professional restaurant. Shared restaurant provide an opportunity for college students to start businesses. Students invest in a campus restaurant, participate in the restaurant menu development and cuisine hot spot analysis, and share the profits of the campus restaurant. Students with computer technology can participate in the development of shared platform and share the operating profit of the operating company after becoming a partner. The internal guest experience store is invested and operated by the operating company. It is a shared restaurant dedicated to the appointment of important customers and the internal personnel of the operation company. For investment-oriented members or intentions of the restaurants, shared restaurant provide excellent materials, as well as high-end customized tableware experience. Franchise restaurants can buy agri-food base of the famous gifted materials or tableware company’s custom tableware, to achieve high-end specialties, tableware sharing. The business model diagram of shared restaurant based on cloud platform is shown in Figure 2.

With the promotion of the brand, the franchise restaurants can get more channels of customers, not only limited to the original customers. Through the predetermined function of the platform, manage restaurants more informatively and reduce the table idle rate. For the low idle rate and popular restaurants, if they join the shared restaurant, the brand will provides high-end tourists and enhance consumption, make restaurants increase profits on the basis of the original attendance rate. For consumers, shared restaurants provide consumers with more convenient and secure food and beverage services to meet the needs of personalized and customized catering services. Membership system provides consumers with substitute coupons and member points, make them enjoy more benefits at the expense of shared restaurants. Compared with traditional restaurants, the operation mode of shared restaurant O2O pays more attention to the integration of online and offline resources, realizes the sharing of free restaurant resources for consumers, and the sharing of idle resources such as food ingredients, chefs and so on for restaurants.
