Research on the hot phenomenon of off-campus catering —— research learning achievements. In recent years, there has been a common phenomenon: although the scale of school canteens is getting bigger and bigger and the environment is getting better and better with the development of society, it has failed to surpass the unusually hot off-campus catering. Most middle school campuses are crowded with people outside at lunch time, and both street stalls and roadside shops are full of charm. Some people even posted a post on the post that "Go to school to sell Dicos at noon", which was strongly welcomed. Why are most students in our school keen on eating in off-campus snack bars? What is the attraction of off-campus catering? Why is the school lunch close to the water tower "not getting the moon"? For this reason, students take our school as an example to study this phenomenon, and draw the following reasons by using relevant knowledge of economics, online voting and sampling survey. First, off-campus dining is more selective, and there is no need to queue up. According to the data obtained from the poll "Why you don't eat in the school cafeteria" initiated by Baidu Post Bar in our school, 62.5% of the students said that "there are too many people in the cafeteria, so they have to queue up" is the main reason why they choose to eat outside the school. For the students who have been studying all morning, it is undoubtedly torture to queue up for meals in a crowded canteen, and some students who love learning are reluctant to spend their time in line. Comparatively speaking, off-campus catering can be more selective, and many small shops and booths can reduce the waiting time of students. Second, there are many kinds of off-campus meals, and the taste is better. In the voting mentioned above, 54.1% of the students think that "the canteen food tastes bad and there are too few kinds" is the main reason why they don't eat in the canteen. For example, foods such as mala Tang, crossing the bridge rice noodles, and board noodles, which have emerged in recent years, are not served in the canteen or taste bad. Another example is that there are too few kinds of pasta in school, and there is only one kind of stuffing and one or two kinds of noodles in steamed buns, which cannot meet the taste needs of modern students. There are many kinds of off-campus dining. Take the surrounding area of our school as an example. There are three or four restaurants serving mala Tang and three noodle shops. There are all kinds of rice noodles, casseroles and stir-fried dishes, and even people who want to eat jiaozi can be satisfied. Balance between supply and demand will naturally lead to successful operation. In addition, the delicious food in off-campus catering is also a big reason for attracting people. Third, off-campus catering has a price advantage. 29.1% of the students think that "canteen meals are too expensive" is another big reason why they are keen on off-campus catering. In the sample survey, nearly 85% of the students think that the price of canteen food needs to be lowered. According to the survey, students with small appetite spend about 6~7 yuan money for a meal, while students with large appetite can sometimes spend more than 15 yuan for a meal, which is obviously beyond a student's ability. And off-campus meals will basically not exceed 6 yuan's money, and some can even be controlled below 4 yuan. So why is the price of off-campus catering so low? According to the survey, most small shops can't guarantee the sanitary conditions in their stores, and the ingredients used are also worrying, not to mention roadside stalls. Low cost, low price; The price is low, and the sales volume is bound to be large. Therefore, it is inevitable that off-campus catering is hot and abnormal. These are the three main reasons for the popularity of off-campus catering. Off-campus catering takes up the lunch time on campus, the geographical position around campus, and the attractive advantage of low price. No wonder it attracts many students. As a member of the school, students have the obligation to contribute to the better construction of campus facilities. Therefore, students suggest that the school appropriately reduce the price of meals, increase the variety of meals and ensure the hygiene of the canteen, and make the above improvements, which will attract more students to eat in the canteen.
