成都卷烟市场比较混乱,而且市场比较封闭。在成都市,卷烟的消费价位在2-5元/盒和7元/盒两种层次。消费者喜欢购买云南卷烟。在一类卷烟中,云南卷烟占据着绝对主动。在调查中,我们得知,云南卷烟的吃味醇香,而且进入全国市场的时间较早,知名度很高,尤其是昆明卷烟厂的“云烟”系列,在当地形成了旺销。而成都卷烟厂的品牌卷烟“娇子”的销售却举步维艰。  相似文献

我国烟草供应链已基本形成"工业企业-商业企业-零售户"的三级供应链结构,在这条供应链中,卷烟商业企业不仅向上游的工业企业提供卷烟市场的需求信息,还通过行使卷烟区域分配权向零售户提供卷烟产品,对销售型供应链起到了至关重要的作用。本文基于SCOR模型,并结合纯销区卷烟商业企业供应链的结构和特征对其进行分析研究。此外,还对SCOR模型在卷烟商业企业供应链中应用的意义进行了阐述和分析,为探索适用于卷烟商业企业供应链流程的最佳优化工具做出了相关研究。  相似文献

This study analyzes data on cigarette purchasing using an extensive panel dataset. Major findings are: (1) cigarette purchasing in this market exhibits a reverse-J, or NBD (Negative Binomial Distribution)-like shape: many infrequent buyers and fewer frequent buyers; (2) Cigarette brands do exhibit high loyalty compared to other consumer categories, and show a trend to higher brand loyalty over time coinciding with fewer price promotions; (3) The data shows a weak double jeopardy pattern of smaller brands enjoying somewhat lower loyalty; (4) Smokers of a given brand are on average more likely to purchase another large cigarette brand than another small brand; (5) A straightforward analysis method identifies occurrences of excessive cross-brand cannibalization in the portfolio of one of the major tobacco corporations; and (6) Certain brands enjoy particular appeal among specific demographic groups. The study sheds more light on consumer behavior towards a product with addictive qualities and known harmful effects.  相似文献

Because of the inconsistency in the findings from past decades of research and the lack of consensus regarding the relationship between advertising exposure and cigarette consumption, the large body of extant research on the effectiveness of cigarette advertising has generated equivocal conclusions on this subject. Therefore, we conducted a comprehensive meta-analysis of cigarette advertising research to determine what impact, if any, cigarette advertising has on cigarette consumption. Unlike previous attempts to synthesize the cigarette advertising literature, this study examined three specific levels of the criterion (i.e., initiation, continuation, and brand behavior) rather than examining only aggregate consumption.  相似文献

Tobacco promotion influences tobacco consumption. Traditional forms of tobacco promotion have been heavily restricted in response to the harmful effects of tobacco. Tobacco displays at the point of purchase are increasingly important as a means of communicating brand imagery for the tobacco industry, especially when advertising is restricted at these points. Previous research has demonstrated that children exposed to tobacco advertising at the point of purchase have inflated perceptions of availability, use and popularity of tobacco. Internationally, laws are being debated and implemented to prohibit or restrict the display of tobacco at the point of purchase or put tobacco out of sight. Such measures would reduce tobacco product exposure and, hence, tobacco marketing among youth and the community. In South Australia, a ban on all cigarette advertising at the point of purchase was introduced in 2005. This study was designed to assess community support for restrictions on cigarette displays and advertising at the point of purchase. A telephone survey was conducted with a random sample of 2026 South Australian adults (aged 18 years and over) in July 2005. Overall, 63% of the community approved of a hypothetical total ban on cigarette displays at the point of purchase, with over three‐quarters believing this should happen in the next 12 months. A further 24% believed that cigarette displays should be restricted and 82% would approve of a ban on displays in stores that sell confectionary. Only 7% of adult smokers reported making their decision about the brand of cigarettes to buy at the point of purchase and 90% made their decision before they even entered the shop. The results strengthen arguments that cigarette displays are not necessary to maintain brand loyalty or to encourage brand switching of established smokers. Instead, the results make arguments more credible that cigarette displays normalize and promote smoking among young people and may also promote unplanned purchase or increased consumption among less frequent smokers or former smokers. Placing cigarettes out of sight would be unlikely to impact on brand choice for most smokers, who have already made up their mind before they enter the store.  相似文献

This paper uses the comparative statics method of testing for a monopoly equilibrium to track the competitiveness of the US cigarette industry between 1955 and 1990. The degree of competition ranged from somewhat less than a Coumot–Nash equilibrium would imply to somewhat more. Although the industry's behavior was highly autocorrelated, there were periodic reversions to behavior that was much more competitive than the trend  相似文献

Despite strong interest on the part of tobacco health practitioners, the effect of graphic warnings inserted on cigarette packs is unclear on several levels. First, the most effective themes for such messages have not been clearly identified by researchers. Second, no research has identified the ideal combination of self-efficacy and fear appeal warnings that should be inserted on cigarette packs, according to Protection Motivation Model principles. The exploratory study we conducted with French consumers to test the effectiveness of new graphic warnings proposed by the European Union in 2004 clearly demonstrates that visual messages, as opposed to text warnings, are more effective. This study also enabled us to identify the most effective themes of the European set: health warnings and social messages. Regarding future public health applications, if fear appeals are used, they need to be combined with self-efficacy and cessation support messages since they provoke avoidance reactions.  相似文献
