2010年上海世博会客流影响因素的实证分析

文章针对世博会运营期间184天的单日入园客流数据,运用多元回归计量分析方法,系统地探讨了单日客流的内、外生影响因素。研究结果发现,上海世博会运营期间的周末效应和长假效应明显,温度变化是影响客流波动的重要负面因素,相对恶劣天气对客流的影响在原始数据中并不显著,但在处理后的数据中显著为负。作为世博会组织程度代理变量之一的团队入园人数对单日客流具有明显的正面影响,指定日的价格提升具有显著的负面影响,入园客流具有滞后的正面影响,而团队入园客流则有显著的滞后负面影响。     

城市特征对城市游客满意度的影响——基于Probit模型的定量分析

游客满意度是衡量城市旅游发展的重要指标之一,掌握和控制游客满意度的影响因素对城市旅游发展和管理越来越关键。国内外研究综述表明,城市旅游的游客满意度影响因素及其关系的定量研究尚不多见,尤其对城市特征因素的研究。城市特征是城市旅游的必要组成,作为客观因素对游客满意度的影响不言而喻。文章运用文献分析法、问卷调查法和二元Probit离散选择模型计量法,以长沙市477名游客的现场调查数据为基础,对城市特征、个人特征和旅游动机三大变量下10个影响因素与游客满意度之间的假设关系进行检验。研究结果显示,修正后的游客满意度影响因素Probit模型具有统计学意义,6个研究假设得到验证;研究结论表明,城市社会发展水平、城市绿化水平、环境保护水平、旅游资源丰富程度、游客月收入、游客是否主动到访等因素对城市旅游的游客满意度产生显著的正面影响,其中,游客主动到访因素对游客满意度的影响作用最大,城市社会发展水平影响作用最小。研究结论一定程度上有利于促使城市管理者更多关注城市发展与旅游质量,最后,从满意度改善系统、城市要素建设、城市旅游资源开发和游客营销引导等方面提出政策建议。     

Examining the Differential Impact of Human Crowding Versus Spatial Crowding on Visitor Satisfaction at a Festival

Human crowding at a festival can affect visitor satisfaction differently to spatial crowding. Festival visitors perceive human crowding as a situation in which the festival is full of people. Spatial crowding, on the other hand, is perceived as restricting movement. We hypothesized that human crowding affects visitor satisfaction in a positive way (by increasing positive affect and decreasing negative affect), whereas spatial crowding affects visitor satisfaction in a negative way (by decreasing positive affect and increasing negative affect). We tested these hypotheses using data collected through an on-site survey at the 2012 Seoul Lantern Festival in South Korea: 423 visitors attending the festival completed the survey. The survey results supported the hypotheses. Managerial implications of the findings are also discussed.     

Can Marine Wildlife Tourism Provide an “Edutaining” Experience?

Marine-based tourism can be both an entertaining and educational experience for tourists – “edutainment”. This research surveys participants of a dolphin watching program in Fiji to assess their motives to participate in dolphin watching. The research also examines the extent to which education and enjoyment of the marine wildlife tourism experience can contribute to intended pro-environmental behavior. The study reveals there is moderate evidence to support the hypothesis. Although the educational aspect of the trip was limited, satisfaction with the experience was high. However, there is an opportunity for increased education and interpretation in the context of the experience.     

Towards Understanding User Perceptions of a Tourist-based Environmental Monitoring System: An Exploratory Case Study

This paper examines user perceptions of a tourist-based environmental monitoring system which supports park visitor engagement with the environmental monitoring of specific sites within two National and one Regional Park in Victoria, Australia. The system allows park visitors (tourists) to actively participate in the care and management of the park by voluntarily contributing to web-based photographic records. The primary objective of this exploratory case study research is to identify who the tourist users are, their perceptions of the system, their motivation for using it, and the benefits that they perceive are derived from using the system. The study found that respondents indicated a strong concern for the environment and appreciated the simplicity of the system and the on-going connection it provides to the park-management process. Importantly, respondents found the system to be a valuable source of engagement with the environmental monitoring and management process.     

Rationalising Inappropriate Behaviour at Contested Sites

This paper examines how tourists justify inappropriate behaviour at contested cultural heritage sites through an analysis of weblogs of people who climbed Uluru, Australia. The climb is increasingly seen as being inappropriate, culturally insensitive and socially unacceptable. Yet it remains open and up to 150,000 people participate each year. Park managers and traditional owners are trying to demarket it with the hope that falling consumer demand will ultimately result in its closure. The study revealed three types of climbers: those who reject the Aboriginality of the place; those with different value sets who see nothing inherently wrong with their actions; and a large group who is aware that its actions may be inappropriate and who, therefore, need to invoke some sort of neutralisation technique to rationalise their decision. This latter group is more likely to respond to behaviour modification messages and should be the main target of future demarketing activities.     

Assessing the temporal stability of the ecotourism evaluation scale: testing the role and value of replication studies as a reliable management tool

Developing scales is a critical step in monitoring and evaluating ecotourism to ensure sustainability. Replicating studies to test if scales are enduring in evaluating visitors’ assessments of ecotourism is also essential to ensure reliability and credibility, and to track changes. This paper reports on a sample of 404 international visitors in Nepal's Annapurna Conservation Area, undertaken in 2012, to test for scale stability and change from a 2006 survey. The original scale was cross-validated by confirmatory factor analysis, and then mean-level change and rank-order stability of scale items were reported. There was strong support for the original factor model in the new sample; all items were loaded on a single construct; their loadings were statistically significant, the root-mean-square error of approximation was .076, the comparative fit index was .993, and the non-normed fit index was .987. Although a statistically significant decrease in the mean of scale items was found, the items’ rank-ordering remained similar. The Spearman's rank-order correlation between factor loadings of 2006 and 2012 was .714 and statistically significant. Cronbach's alpha was .845, comparable to the previous alpha of .910. The ecotourism evaluation scale showed temporal consistency but also detected changes in visitors’ attitudes requiring management attention.     

An Empirical Study of Behavioral Intentions in the Food Festival: The Case of Macau

The behavioral intentions of visitors play an important role in predicting future profits in the food festival. The purpose of this study is to identify the dimensions of festival quality and examine the interrelationships between behavioral intentions and the other constructs related to behavioral intentions as perceived by visitors to the food festival using structural equation modeling (SEM). The dimensions of festival quality are built and a multi-dimensional and hierarchical model is used as a framework to synthesize the effects of festival quality and visitor satisfaction on behavioral intentions of visitors to the Macau Food Festival (MFF). The findings of this study are based on SEM analysis of a convenience sample of 428 respondents. The findings reveal that there are four primary dimensions and 11 sub-dimensions of festival quality in the MFF.
