Estimating Recreation Preferences Using Hedonic Travel Cost and Random Utility Models

Over the last decade, several authors have questioned thevalidity of the hedonic travel cost model, arguing instead that the random utility model is a superior method forvaluing recreational site attributes. This paper demonstrates that the two methods emanate from a similar utilitytheoretic framework; yet in practice these methods differ in the assumptions made in their application.Constraining the underlying utility functions to be consistent, both models are applied to the valuation ofrecreational site attributes in the Southeastern United States. The way in which each method estimates preferencesfor site attributes is shown to depend critically on the method and the functional form of theunderlying utility function.

基于员工维度的旅行社业绩评价体系研究

业绩评价是旅行社进行科学管理的重要手段。智力密集型、服务型和相关型的旅行社行业属性,使员工人力资本体现出能动性及与内外部高度合作协调性的特征,成为旅行社竞争能力的核心资本。缺乏员工维度的业绩评价就会在一定程度上导致员工流失率上升和行业中＂柠檬市场＂现象的出现。文章从旅行社业绩形成动因的逻辑分析入手,构建了以员工满意度和员工服务效率结果指标为核心的旅行社业绩评价体系,并以此为基础从成本指标、时间指标及质量指标等过程指标角度进行了具体细化衡量。     

入境旅游与对外贸易的关系——基于中国2001—2008年月度数据的实证分析

根据SITC将中国对外贸易商品分为初级产品和工业产品,并按目的不同将入境旅游分为商务旅游和休闲旅游,利用2001—2008年的月度调整数据,分析中国不同目的的入境旅游与不同类别对外贸易的关系。具体步骤是:首先对相关变量的序列平稳性进行单位根检验,并通过协整检验分析二者之间的长期均衡关系,然后通过格兰杰检验进一步分析二者之间的因果关系,结果显示:初级产品的出口随时间平稳增长,对外贸易进口和商务旅游之间没有长期的稳定关系,工业产品出口、对外贸易出口和入境旅游之间存在双向因果关系,其他入境旅游各类别和对外贸易各产品类别之间存在单向因果关系。根据实证分析的结果并针对中国当前的现状提出了相应的政策建议。     

我国国际资本流动：直接投资与非直接投资影响因素的比较研究

本文基于向量误差修正模型对1982-2010年期间我国直接投资类、间接投资类（含其他投资）、错误与遗漏及投资收益类三种类型国际资本流动的影响因素进行了实证研究。实证检验结果表明：在长期,我国三类国际资本流动与人民币对美元的实际汇率升贴水年率之间为负向变动关系,与中美利差、中美通胀之差、我国实际经济增长及人民币对美元的实际汇率预期之间为正向变动关系;在短期,三类国际资本流动与上述影响因素之间关系并非一致;实际经济增长是我国直接投资类国际资本流动的主要原因,人民币对美元的实际汇率预期是我国非直接投资国际资本流动的主要原因。     

环境质量变化对游客福利的影响——基于旅行费用和条件行为联合数据

环境质量是影响游客旅游需求及福利的重要因素,但单一使用陈述性偏好法或揭示性偏好法仍存在诸多局限性。为探究环境质量改变对游客需求及福利变化的具体影响,结合旅行费用与条件行为数据,在明确现有环境质量状况下景区价值基础上,评估环境质量改善与恶化两种情景下,游客消费者剩余的变化。结果表明,环境质量改变直接影响旅行次数,从而增加或减少消费者剩余,但不会通过影响游客旅行费用间接改变消费者剩余,实际行为与条件行为数据偏好存在一致性;白洋淀景区当前消费者剩余为909.09元/次;环境质量改善使游客平均旅行次数增加1.45次/年,并使每位游客每年的消费者剩余增加1 318.18元;环境质量恶化使游客平均旅行次数降低1.41次/年,并使每位游客每年的消费者剩余减少1 281.81元。     

论旅游线路的文化品味提升:基于非物质文化遗产的视角——以珠三角为例

通过广州、深圳、佛山、东莞和中山五城市旅游线路的调查,非物质文化遗产作为一种较高级别的旅游资源未得到旅行社的足够重视。针对国内旅游线路缺乏创新,欠缺文化内涵的现状,对旅行社的旅游线路进行改造,融入非物质文化遗产的项目,旨在通过提升线路文化品味的同时促进非物质文化遗产的传承和发展。     

Adding a freight network to a national interstate input–output model: a TransNIEMO application for California

The state of the nation’s infrastructure is the subject of widespread discussion and comment because it is thought to include many deteriorating and unsafe bridges. Ever since the terrorist attacks of 9/11, there has been increasing concern over the extent to which an attack on infrastructure could result in serious economic disruption. This research develops a model to analyze the economic consequences of an attack on a major element of the highway network. We add a freight network to a national multiregional economic impact model and make freight traffic flows endogenous. The use of a sub-national interstate model recognizes that most infrastructure planning is at the state level and most political leaders’ interest is local. We base our approach on the National Interstate Economic Model (NIEMO) and refer to an elaboration that we name Transportation network and the National Interstate Economic Model (TransNIEMO). The new model enables us to study the state-specific and industry-specific economic impacts of some significant changes in the nature of highway freight movements. We tested the model for selected freight movements in and out of California. The results are entirely plausible and encourage us to elaborate and test the model for hypothetical disruptions of freight traffic throughout the US.     

Financing preferences: evidence from the Korean market

We investigate the financing decisions of Korean firms during the period of 1996–2015. Korean firms follow a matching strategy for funding their cash needs. Cash inflows from investing activities are the primary source of funding for capital expenditures, and cash inflows from financing activities are the major means of covering cash outflows from financing activities. We also find that Korean firms’ financing practice of handling cash deficits can be described by the pecking order model modified and augmented by cash flow variables. Cash inflows from investing activities account for the major portion of financing to make up for cash deficits, followed by short- and long-term debt, and then equity financing.
