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。     

基于DEA-SBM模型的中国地板上市企业环境效率研究

考虑非期望产出,基于企业层面,根据2011-2016年数据,采用DEA-SBM模型与DEA-CCR模型对中国12家地板上市公司的环境效率与经济效率进行测算与比较。结果表明:2016年环境效率和经济效率测算结果显示不同地板上市企业运行效率存在差别;与经济效率相比,一些企业如北新建材、扬子地板,环境效率保持不变,一些企业如宜华生活、吉林森工和丰林集团,环境效率得到提升;还有一些企业如兔宝宝、升达林业和大自然家居等,环境效率则出现下降。考虑了非期望产出,中国地板上市企业整体环境效率均值低于经济效率均值,总体处于0.79~0.84之间。提出了政府应加强监管力度,地板上市企业应提高技术改进能力,建立完善社会责任信息披露机制的建议。     

土地利用变化驱动力多尺度因素的定量影响分析

研究目的:揭示多尺度土地利用变化研究中尺度因素对驱动力的定量影响。研究方法:构建Logistic回归模型和二分类反应变量两水平Logistic回归模型,分别基于面向尺度对比的多尺度回归分析和基于系统观点的多水平模型分析两个角度,探讨多尺度土地利用变化核心驱动力及其定量影响关系,并对两类模型的分析结果进行对比分析。研究结果:面向尺度对比的多尺度回归分析法能够从更为微观的角度揭示各个尺度层级上地类变化的核心驱动因子,而基于系统观点的多水平模型分析方法则能够更好地顾及尺度因素的定量影响。研究结论:多水平模型分析方法揭示的各个地类的核心驱动因子集与多尺度回归分析法推导的对应地类的核心驱动因子集之间呈现子集关系,两者在多尺度土地利用变化驱动力的研究方法上能够形成互补。     

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.     

长江三角洲地区工业地价形成的内在机理与博弈分析

研究目的:针对长江三角洲地区工业地价之间的压价恶性竞争,通过建立实证模型阐述工业地价形成的内在机理和城市间的博弈过程,为促进该区域间的合理博弈和协作提供参考.研究方法:Delphi法,相关分析方法.研究结果:分析了工业地价形成的内在机理,并且构建了最优地价模型.研究结论:当前经济发展水平、城市路网密度、城镇居民可支配收入、协议出让土地面积所占比例是影响长江三角洲地区城市工业地价形成的主要因素,并对工业地价形成的作用程度不同.推进工业用地市场化、建立信息公开制度、制定跨区域的国土规划、完善土地管理制度、构建新型土地税收体系是推进长三角地区从非理性博弈过渡到理性博弈的有效途径.
