英文文献摘要：
A two stage model describes the behavior of anglers who fish with or without a license. The proposed multinomial logit-count data model examines characteristics influencing those who fish for recreation and those who may choose to fish to supplement their food budgets. The model is estimated using data from the national survey. Results show, among others, that anglers who fish to supplement their diet are more likely to come from households run by women, with less income and were less educated than those who fished for recreational purposes.

一个两阶段模型描述了有许可证或无许可证钓鱼的钓鱼者的行为。提出的多项对数计数数据模型检验了影响那些为娱乐而钓鱼和那些可能选择钓鱼来补充他们的食物预算的特征。该模型是根据全国调查的数据估计的。结果显示，与那些以娱乐为目的的垂钓者相比，那些为了补充饮食而垂钓的垂钓者更有可能来自由女性经营的家庭，他们收入较低，受教育程度也较低。
