英语翻译
The experimental design approach we propose builds on recent work by Dellaert,Borgers and Timmermans (1996,1997) who introduced experimental designs to support the estimation of nested logit and heteroscedastic logit models of consumer choices of activity patterns.Specifically,they applied a structure of independent sub-experiments to obtain independent estimates of consumer utilities of different elements in consumer service portfolios.We extend their framework to construct an experimental design that supports both separate and integrated estimation of consumer utility functions for different purposes and locations in consumer shopping trip choices.
To achieve our objectives,this paper is organized as follows.In the next section we give a formal description of the proposed multi-purpose multi-stop model.This is followed by two brief sections which introduce the proposed experimental approach and discuss model estimation.An empirical application,which investigates the tendency of Dutch shoppers to combine grocery,drugstore and clothing purchases across multiple shopping destinations,is given in the next section.The paper closes with a summary of our main conclusions,a discussion of potential management implications of the model findings,and some suggestions for future research.

这是篇经济专业文章的前言吧,因为以前得到过百度的帮助,所以,不是字对字翻的.
我们推荐的试验方法是建立在Dellaert,Borgers和Timmermans三位近期的工作成果基础之上的,由他们引入的试验设计方案可以提供对消费者选择行为的巢式逻辑模型和异方差逻辑模型的估算支持.值得一提的是,他们提供了一种独立子试验架构,在这一架构中,可以针对由消费者服务组合中的不同因素构成的消费效用得出独立的估算结果.我们对他们的架构进行了扩展,建立起一个试验性的设计,可以根据消费者购买行为中游离性选择的不同目的和环境,同时对相独立的和集成的消费效用方程进行估算.
言归正传,本文的组织如下.下面的部分我们给出了对multi-purpose 和 multi-stop模式的形式化描述.随后两个部分分别引入建议的实验方法和对模型的估算进行讨论.接下来的一节里有一个经验应用案例,考察了结合杂货店,药店和服装店等多个购物地点的荷兰购物者的偏好趋向.本文的结尾部分是对我们的主要结论的概括,针对模型结果给管理带来的潜在影响的讨论,并为未来研究提出了一些建议.
