在这篇论文中，我们试图以经验量化同伴社会网络在解释青少年饮酒行为中的作用。使用来自全国代表性青少年样本的数据，我们利用具有学校水平固定效应的多变量结构模型来解释背景效应、相关效应和同伴选择的问题，以消除同伴影响估计中的潜在偏差。我们的同伴群体衡量标准不仅来自亲密朋友的提名，也来自同学的提名。同伴群体中的饮酒行为是根据同伴自己的饮酒报告来构建的。在控制了家长层面的特征和其他人口统计参数后，我们发现，同学中饮酒的比例每增加10%，参加饮酒的可能性和频率就会增加大约4个百分点。我们还发现证据表明，亲密朋友的影响虽然仍然显著，但在考虑了未观察到的环境混杂因素后，其影响程度有所下降。我们的研究结果支持了文献，即同伴效应是饮酒行为的重要决定因素，即使在控制了潜在的偏见之后。旨在减少青少年酒精消费的有效政策应考虑到这些显著的同伴效应。2009爱思唯尔有限公司版权所有。
In this paper we seek to empirically quantify the role of peer social networks in explaining drinking behavior among adolescents. Using data from a nationally representative sample of adolescents we utilize a multivariate structural model with school-level fixed effects to account for the problems Of Contextual effects, correlated effects and peer selection to purge the potential biases from the estimates of peer influence. Our peer group measures are drawn not only from the nomination of close friends, but also from classmates. Drinking behavior among the peer groups was Constructed using the peers' own report of their alcohol consumption. Controlling for parent level characteristics, and other demographic parameters, we find that a 10% increase in the proportion of classmates who drink will increase the likelihood of drinking participation and frequency by approximately four percentage points. We also find evidence to show that the influence of close friends, while still significant, diminishes in magnitude after accounting for unobserved environmental confounders. Our findings support the literature that peer effects are important determinants of drinking behavior even after controlling for potential biases. Effective policy aimed at reducing alcohol Consumption among adolescents would consider these significant peer effects. (C) 2009 Elsevier Ltd. All rights reserved.
