Shallow view college students（浅析大学生消费观） In the current consumption market, as a special group is receiving more and more attention. Cell phones, Internet, sports, tourism, av equipment are students of consumption. Their younger age, different from other social consumer groups of consumer psychology and behavior. On one hand has strong consumption demand, on the other hand, has obtained the financial independence. Consumer spending power of advanced concepts, the lag and has great influence on them. With this curious, we investigated the students listened, currently the teachers.Results showed that the following reasons for college students have a profound influence on the view.First, family environment for students of consumption "congenital". Family is the basic factors restricting their consumption. Most students from rural areas currently. Rural students would not spend a lot of money to buy a bar of chocolate, biscuit, candy and snacks. A classmate of institute of grammar, told reporters he every month in the consumption of food and supplies, and a small part of life. However, the students from the developed city, in the free allowance is master circumstance, even the remaining money to spend on hair, clothing, accessories, and other items. MP3 Second, the consumption of college campus environment. According to the understanding of the ", just past 11 golden weeks, "some travel agency" lovers swims "travel group, a lot of students. Some boys to girls, the pursuit of cosmetics, snacks, flowers as "sociology". In the investigation and discussion, we found that the students love more than 100 - month about spending at least 200 yuan, also has 50 yuan, the highest reach 500 yuan. One of the students of agronomy humorously tells a reporter, dating from the average expenses for the situation had been broken and three kinds, namely, man should take all NanNvFang share and the initiative of all, girls love spending even more than the situation.Internet addiction among is one where money. Some students spend all day in the net cafe, wasting their time and energy, and parents hard-earned money.Third, social environment influence on college students' view. In the interview process, a eppo school students told reporters: "some students fashion and famous, too." compare existing In the seminar, some students, in order to have a phone or a paragraph on the most popular, some classmates to economize, even sacrifice other necessary expenses. Some male classmate to buy a pair of shoes, the female classmate brand in order to buy a set of famous cosmetic or a brand-name clothes at hand to his family, money or borrow money from their classmates, these reflects some students don't know into, and driven them form the vanity of endless themselves. In addition, the male classmate hair, earrings, female students, also make positive modelling teachers and parents worried.College students are the pillars of the construction of the future society, its consumption ideas and directly affected the life character and the influence of the motherland, indirect jiangshan justice. Good training and strengthening consumer habits will get to the school, good shape, and formed the role of school student wind virtuous circle. Therefore, the schools should set students' good consumption psychology and behavior of the cultivation of campus culture construction as an important component. Facing the current as of inviting advertising the snowflake fly to the university campus, teachers and parents have necessary guidance from the side with the correct method, students correct view firmly. College students from his actual consumption of the economic situation, develop simple life style, develop good consumption habits and consumption mentality. 在当前的消费市场中，大学生作为一个特殊的消费群体正受到越来越多的关注。
手机、旅游、上网、运动、影音器材都是大学生的消费热点。他们年龄较轻，有着不同于社会其他消费群体的消费心理和行为。
一方面有着旺盛的消费需求，另一方面，尚未获得经济上的独立。消费观念的超前和消费实力的滞后，都对他们有很大影响。
带着这样的好奇，我们调查了农大的同学，听取了老师们的意见。 调查结果显示，下面几种原因对大学生的消费观有着深刻的影响。
第一，家庭环境对大学生的消费观产生“先天性”的影响。家庭条件是大学生消费的根本制约因素。
农大学生大部分来自于农村。农村来的学生不愿花费很多钱去买巧克力、饼干、糖果之类的零食。
文法学院的一位同学告诉记者，他每个月的消费大部分用在伙食及学习用品上，还有一小部分是生活用品。但是，来自发达城市的学生，。
