基于引力模型的中美农产品贸易边境效应研究

针对中美两国在农产品贸易上的新变化,应用引力模型的派生模型——边境效应引力模型对中美两国农产品贸易的流量和流向进行理论和实证研究。首先介绍了边境效应引力模型基本模型的推导过程,并引入了调整模型。然后采用1987至2005年其中5年的截面数据进行计算,结果发现:中美农产品贸易的边境效应显著存在,且呈逐年下降趋势;两国之间的农产品贸易边境效应存在流向和区域上的差异;距离的平方并不影响模型的可靠性。     

Do satisfying walking and cycling trips result in more future trips with active travel modes? An exploratory study

Previous studies have indicated that travel satisfaction - the experienced emotions during, and cognitive evaluation of, a trip - can be affected by travel mode choice and other trip characteristics. However, as satisfactory trips might improve a person's attitude towards the used mode, persons may be more likely to use that same mode for future trips of the same kind. Hence, a cyclical process between travel mode choice and travel satisfaction might occur. In this paper we begin to analyse this process—using a structural equation modelling approach on cross-sectional data—for people who engage in walking and cycling for leisure trips in the Belgian city of Ghent. The focus on walking and cycling reflects recent studies indicating that active travel is often associated with the highest levels of travel satisfaction. Results of this exploratory analysis offer tentative support for the idea of a cyclical process: the evaluation of walking and cycling trips positively affects the respondents' attitude towards the respective mode, which in turn has a positive effect on choosing that mode.     

Psychological factors affecting memorable tourism experiences

This study tries to explore psychological components of memorable tourist experience (MTE) that are most likely to recall tourists’ memories. Urban residents from three representative cities in China were selected as research samples, and totally 301 usable questionnaires were used for data analysis. The results showed that the recollection of MTE was positively affected by novelty, involvement and social interaction. It was also suggested that hedonism and novelty had positive effects on the vividness of MTEs significantly. Additionally, in the context of Chinese culture, two new psychological factors, social interaction and perceived serendipity, resulted in different effects on the MTE.     

基于IPEA方程思想的江苏省节能潜力分析

基于IPEA方程思想,对江苏省能源消耗进行了历史回顾,预测了2010年、2015年和2020年的江苏省能源消耗总量;通过产业结构演进—能源消费和产业结构演进—单位GDP能耗两个模型,分析了1985年以来江苏省产业结构演进与能源消费和单位GDP能耗的关系,结果显示,产业结构演进与一次能源消费总量和单位GDP能耗之间存在着密切的关系,通过IPEA方程分析和预测可知,在按GDP年递增率0.10的情况下,如果单位GDP能耗递减率低于0.0909,能源消耗量会增加。在今后的发展中,江苏省应继续通过一系列产业结构调整和优化措施,降低能源消耗。     

PI背景下的TDI结构方程模型

态度理论为地区形象(PI)和旅游目的地形象(TDI)的联合研究提供了一个平台。本文构建了一个理论上的地区形象背景下的旅游目的地形象结构方程模型。模型是一个具有因果关系的结构方程模型,包括8个潜变量和28个观测变量。以徐州为例,在运用SPSS15.0软件对数据进行信度检验的基础上,利用LISREL8.70软件对模型进行了验证性因子分析和路径分析。研究发现:(1)结构模型中各潜变量之间的路径与假定基本符合,模型的整体拟合性能良好;(2)旅游资源认知和旅游服务认知会对旅游意愿产生作用,这符合我们的传统理念;(3)地区特征和居民素质对旅游服务感知、目的地评价和旅游意愿三者均有效应,而地区竞争力和居民竞争力仅对旅游服务感知产生影响。

古村落居民地方依恋与资源保护态度的关系——以西递、宏村、南屏为例

本文以皖南的西递、宏村和南屏等3个古村落为例,设计量表测量了古村落居民的地方依恋,通过构建结构方程模型探讨了居民地方依恋与其资源保护态度的关系。研究结果表明：（1）古村落居民的地方依恋由地方依赖（ξ）和地方认同（η1）两个维度构成;（2）地方依赖（ξ）对地方认同（η1）有显著的正向影响（γ11=0．87,t=13．13）;（3）地方依赖（ξ）和地方认同（η1）对居民的资源保护态度（η2）有显著的正向影响（γ21=0．57,t=9．85;β21=0．66,t=10．20）;（4）地方依赖（ξ）主要是通过地方认同（η1）影响居民的资源保护态度（η2）,地方认同在其中起着中介作用（γ21直播=0．26,t=1．69;γ21间接=0．36,t=2．79）。本文的研究对古村落的资源保护以及古村落居住新区的建设有一定的现实指导和借鉴意义。     

Key impact factors of visitors’ environmentally responsible behaviour: personality traits or interpretive services? A case study of Beijing’s Yuyuantan Urban Park,China

The environmentally responsible behaviour (ERB) facilitates the sustainability of tourism destinations. This study aims to identify the key impact factors to promote visitors’ ERB in urban park and examine the impact mechanism. A total of 567 visitors were surveyed in Beijing’s Yuyuantan Urban Park. Structural equation modelling results indicate that personality traits are the most important factors that affect visitors’ ERB, while the effect of how satisfaction with interpretive services plays upon visitors’ ERB using place attachment as a mediator. Openness traits positively affect satisfaction with experiential services and general behaviour. Additionally, implications in urban park management are provided.     

The influence of attitudes towards healthy eating on food consumption when travelling

This study explores tourists' attitude towards healthy eating and its influence on their travel eating behaviour. Based on focus group interviews and literature review, two instruments were developed to measure healthy eating attitude and travel eating behaviour. Factor analysis results revealed two healthy eating attitude factors (‘food content and nutrients’ and ‘balanced diet and eating habit’), and five travel eating behaviour factors (‘novelty’, ‘risk avoidance’, ‘health steadfastness’, ‘familiarity’, and ‘food supplement and medicine’). The relationships among the factors were examined using structural equation modelling. The findings revealed that respondents who had a stronger attitude towards ‘balanced diet and eating habit’ tended to be more motivated by the ‘novelty’ factor; whereas ‘risk avoidance’, ‘health steadfastness’ and ‘familiarity’ were found to be associated with a stronger attitude towards ‘food content and nutrient’. The findings suggest that the healthy eating attitude construct is multidimensional and healthy eating conscious tourists should not be treated as a homogeneous group.     

Determinants and outcome of career competencies: Perspectives of hotel managers in China

This study aims to explore the determinants and outcome of career competencies. Based on the notion that organizations and individuals have respective obligations in the career management of employees’, this study developed perceived “organizational career management’ (OCM) and “career commitment” as determinants and career satisfaction as an outcome of career competencies. Data were collected in the state-owned hotels in China, and structural equation modeling was used to test the proposed relationships. The findings indicate that both perceived OCM and career commitments have positive, direct effects on career competencies. The findings of this study may benefit both hotels and hotel employees by providing valuable implications.
