find the right management policy for the enterprise. The methods of market research in catering enterprises are basically the same as the common market research methods in enterprises, but the contents are different. The commonly used methods are as follows: 1. Inquiry method

Inquiry method is a method of collecting market information by inquiry, which is the most commonly used method to investigate and analyze consumers' buying behavior and intention. Inquiry generally requires the interviewee to answer specific questions, such as opinions or suggestions on the taste, price, service, quality and serving speed of dishes. The inquiry method can be divided into the following categories: (1) the collective questionnaire method is to use the form of questionnaire to select a certain unit or a part of people, and each person answers within the specified time according to the requirements of the questionnaire, and the investigator collects it on time and sorts it out to obtain market information. The advantages of this research method are a wide range of objects, a large survey area, ample time for the interviewees to consider the answers and less expenses. However, the recovery rate of the questionnaire is generally low, and it is not suitable for investigating more complicated problems. (2) interview interview method is that investigators directly visit the respondents and have face-to-face conversations to collect market information. The advantages of this method are face-to-face conversation, no restriction of questionnaires, flexibility, mutual communication and discussion, easy access to deeper information and materials, enhanced understanding and development of relations with customers. The disadvantage is time-consuming, and the investigation results are influenced by the quality of the inspectors. Therefore, this kind of investigation should also draw up an outline in advance and drive the conversation. (3) Desktop design method Desktop design method is to design a questionnaire that is easy to cause customer dissatisfaction and has universality, and put it on the dining table, so that guests can take the initiative to fill it out when eating. This method is quite common in our catering industry. Its advantage is that customers can put forward their opinions at any time, which is convenient for enterprises to correct them at any time without causing great influence. In addition, guests will have a long time to observe the restaurant with the questions in the questionnaire, so the opinions or suggestions withdrawn in this way are authentic and positive. However, the disadvantage of this kind of survey is that it can't be actively filled in by guests, so the recovery rate is low. (4) telephone inquiry method telephone inquiry method is to ask the respondents questions or solicit opinions by telephone. This method is mainly used for the investigation of group guests, but it is generally not used for individual guests. The advantages of this method are convenience, rapidity and low cost, but the disadvantage is that it is impossible to ask complicated questions due to time constraints. Second, observation observation is a research method in which investigators go to the investigation site to observe directly. The advantage of observation method is to use observation from the side instead of face-to-face inquiry, so that the respondents do not feel that they are being investigated, so as to obtain more objective first-hand information. In addition, observation method can be adopted for some contents that are not suitable for inquiry, such as the passenger flow in front of the restaurant, the traffic volume, the number of diners and the number of diners at each table. Observers can be market researchers, service personnel, and auxiliary means, such as cameras and cameras. Observation can be divided into the following categories: (1) Direct observation. Direct observation means that market investigators go directly to our field to observe the consumption situation of the market in order to obtain the required information. (2) The actual measurement method is to actually measure the effect of a marketing activity in order to obtain information. Such as the number of diners after discount, the turnover rate after free drinks or the change of operating income. (3) Behavior recording method Behavior recording method is to record the behavior of the respondents in a certain period of time by investigators in a specific way, and find out the required information from the records. For example, the time for consumers to order food, the number of dishes per capita, the time for eating, etc. Third, the experimental method is a method of conducting small-scale experiments under certain conditions, and understanding its development trend through observation, inquiry and analysis. For example, restaurants (halls) raise or lower the prices of individual dishes, observe or visit consumers' reactions to judge the impact of price changes on sales. For another example, if you want to buy new varieties or flavors, you can experiment in a small area in advance, ask for opinions, find out the direction of the dishes or flavors, and then decide whether it is right or not. Fourth, data analysis data analysis method is a survey method that uses internal and external ready-made data and uses statistical methods to analyze the survey items. This is an indirect investigation method, which is simple and easy, saving manpower and financial resources. Using this method, we should collect all the information needed for each species as far as possible, so please be familiar with the analysis and research of business personnel. This method can also make up for the lack of direct investigation. However, the data analysis method is based on historical data, and various factors that are changing in reality are not among them, which is its shortcoming. The commonly used forms of data analysis are: (1) development trend analysis, that is, the past data are accumulated for analysis and comparison, and reasonable extension is made to analyze the development trend. For example, through the statistical analysis of the annual operating income of the catering industry in the past five years, we can get the increasing or decreasing trend of the operating income of the catering industry in the country. However, this method can only emphasize the analysis of a certain variable, and how to cause such a change can only be obtained through other investigation methods. (2) Correlation analysis In order to find the relationship between one variable and another, positive and negative correlation factors can be analyzed. For example, the rise and fall of cooking materials in the market will inevitably affect the price of dishes. If the price of dishes remains unchanged, it will inevitably affect the gross profit margin or profit margin. Another example is that building roads in front of restaurants may affect the business of restaurants. It is a common problem in our investigation that the change of one factor causes the change of related factors. V. Entrustment method Entrustment method is to entrust an investigation agency to collect data and information, sort out useful information for the enterprise, and thus determine the investment intention and business strategy of the enterprise. Fixed field positioning, etc. In particular, modern catering enterprises must conduct market research to expand the market in different places, and must understand the acceptance of local consumers' products, cultural identity, consumer spending power, consumption habits and so on. For example, there is a big difference between the development of Sichuan cuisine enterprises in the south and in the north. Southerners don't drink much, while northerners drink, which determines that the development of dishes and the gross profit margin of dishes are different.
