目的为了评估2011年苏格兰禁止在零售商店进行多次购买酒精促销的影响。设计和设置差异中的差异分析被用来估计2010年1月至2012年6月期间，苏格兰家庭与英格兰和威尔士家庭相比，禁止对酒精购买量的影响。英格兰和威尔士.四种酒类的购买记录（啤酒和苹果酒，葡萄酒，烈酒和调味酒精饮料），以及纯酒精购买总量。苏格兰的多次购买禁令对整个人口或个别社会经济群体的酒精购买量没有显着影响。对于那些禁令前大量购买酒精的人也没有显着影响。大多数多重购买是为了啤酒和苹果酒或葡萄酒。禁令实施后，涉及购买啤酒和苹果酒的购物次数增加了9.2%（P < 0.01），而每次购物的产品数量减少了8.1%（P < 0.01）。然而，对于葡萄酒，这些影响并不显着。ConclusionsBanning多买促销活动在苏格兰的酒精并没有减少酒精购买在短期内。要实现这一点，可能需要对价格促销和价格进行更广泛的监管。
AimsTo evaluate the impact of the 2011 Scottish ban on multi-buy promotions of alcohol in retail stores.Design and settingDifference-in-differences analysis was used to estimate the impact of the ban on the volume of alcohol purchased by Scottish households, compared with those in England and Wales, between January 2010 and June 2012.ParticipantsA total of 22 356 households in Scotland, England and Wales.MeasurementsRecords of alcohol purchasing from each of four categories (beer and cider, wine, spirits and flavoured alcoholic beverages), as well as total volume of pure alcohol purchased.FindingsControlling for general time trends and household heterogeneity, there was no significant effect of the multi-buy ban in Scotland on volume of alcohol purchased either for the whole population or for individual socio-economic groups. There was also no significant effect on those who were large pre-ban purchasers of alcohol. Most multi-buys were for beer and cider or for wine. The frequency of shopping trips involving beer and cider purchases increased by 9.2% following the ban (P < 0.01), while the number of products purchased on each trip decreased by 8.1% (P < 0.01). For wine, however, these effects were not significant.ConclusionsBanning multi-buy promotions for alcohol in Scotland did not reduce alcohol purchasing in the short term. Wider regulation of price promotion and price may be needed to achieve this.
