随机利率影响下信用风险的Monte—Carlo模拟

在前人利用马尔科夫链表示公司信用等级的基础上,将信用等级和随机利率引入离散时间的信用风险模型中,从而提出随机利率影响下的新的信用风险模型。就上述模型,对不同初始信用等级、初始盈余以及不同时刻的破产概率进行Monte—Carlo模拟,并讨论了相同条件下初始盈余与破产概率、初始信用等级与破产概率以及时间长短与破产概率之间的相互关系。     

五种旅游信息传播模式的比较与整合

旅游信息传播是旅游活动的核心过程,也是旅游研究的重点领域.文章通过梳理相关研究成果,对比分析5种具有代表性的旅游信息传播模式,对其学科属性、概念内涵、模式结构、表述类型等内容进行归纳总结.在此基础上,文章从系统科学、社会心理学和社会伦理学切入,整合并重构旅游信息传播的过程及其结构要素,提出一个由传播者、信息、媒介、游客4大要素为主体,以大众传播、人际传播、组织传播、群体传播为传播方式,并以三环结构为几何特征的旅游信息立体传播模式,为旅游信息传播研究提供了一种新的框架和思路.     

Chinese Residents' Demand for Outbound Travel: Evidence from the Chinese Family Panel Studies

This paper investigates potential factors influencing Chinese residents' demand for outbound travel. Based on survey data from the Chinese Family Panel Studies project conducted in 2008, we utilize several discrete choice models to analyze (1) factors explaining Chinese residents' participation in outbound travel in the last five years and (2) factors explaining various types of outbound travel. We highlight the importance of age, hukou type, personal income, education level, domestic tourism participation, foreign language proficiency, life satisfaction, and Internet use to explain Chinese residents' outbound travel. We also observe regional differences and urban–rural differences by estimating the model using different sub-samples. Finally, implications are presented concerning marketing efforts in targeting potential Chinese outbound tourists.     

Empirical study on Chinese tourists’ perceived trust and intention to use biometric technology

This paper presents a theoretical model based on the Technology Acceptance Model combined with a perceived trust model. SPSS 23 and Amos 22 were used to analyze Chinese tourists’ responses regarding use of biometric technology in hotels and to assess whether their perception of trust – measured through five potential factors – affected their intention to use it. Chinese tourists traveling in Macau were recruited, and three types of biological identification technology were discussed. A total of 600 questionnaires were sent out, and 583 effective questionnaires were recovered. The results that in addition to perceived ease of use, other factors affected visitors’ perceptions of trust. The degrees of effectiveness, however, differed between the three biological identification technologies. Fingerprint technology was revealed to be the most trusted and accepted biometric technology.     

Online Customer Experience and Its Relationship to Repurchase Intention: An Empirical Case of Online Travel Agencies in China

The study reported here examines the relationship between flow experience and repurchase intention by focusing on the joint mediating effects of loyalty. Data were taken from a survey of shopping experiences, at online travel websites, of 325 customers in China. The results show that flow experience has a significant effect on repurchase attention. Moreover, interactive speed, skill, challenge, perceived control, telepresence, perceived usefulness, and perceived ease of use are positively related to flow experience. Lastly, the findings show that loyalty, to some extent, acts as a mediator between flow experience and repurchase attention.
