The diffusion of technologies from other sectors, and innovations in kitchen equipment, fueled structural changes within the foodservice industry. However, this change comes at a price of disrupting the critical step of assessing the demand forecast accuracy. This study aims to explore a surprisingly unique and elevated complexity when assessing the critically important demand forecast accuracy.

The paper develops a mathematical model to describe and explore the nature of the problem in structural biased demand forecast accuracy assessment. It then uses numerical simulation to construct a market example to gain better insights on the bias characteristics. Finally, the forecast accuracy measurement’s inherent bias is contrasted with that of other typical hospitality forecasting setups.

This paper outlines the theoretical underpinnings of how demand forecasts in the central kitchen setup are dynamic and thus produce a structural bias. More specifically, this paper discovers how, in this context of orders from a central location, the forecasts set the capacity constraints, and, consequently, generate a considerably more biased forecast accuracy measure. Relying on such forecast accuracy measures can lead to serious negative business outcomes.

To the best of the author’s knowledge, this study is the first to show that in the unique new technology enabled environment of central kitchen operation, where daily dish demand forecasts set the daily constrained capacity levels, the accuracy measure is severely biased, and consequently accuracy is likely to deteriorate, which in turn, could lead to suboptimal decisions. The major theoretical contribution of this study is a novel analytical model which explains and describes the bias in the accuracy measurement.

技术从其他行业的传播以及厨房设备的创新推动了餐饮业内的结构变化。然而, 这种变化直接影响了评估需求预测准确性。本研究探讨了在餐饮业结构改变后，评估至关重要的需求预测准确性时所面临的令人独特和复杂性。

本文自研了一个数学模型来描述和探讨评估需求预测准确性中的结构性偏差的本质。然后, 使用数值模拟构建一个市场示例, 以更好地了解上述偏差的特征。最后, 将这种预测准确性评估的系统性偏差与其他传统的餐饮业需求预测情境进行对比。

本文概述了中央厨房运营中需求预测是动态的, 因此产生了结构性偏差的理论基础。更具体地说, 在使用中央厨房并集中订单的情境下, 本文发现需求预测直接设定了容量限制, 因此产生了在需求预测准确度衡量中的结构性偏差。依赖这样的预测准确性度量可能产生严重的负面商业结果。

这项研究首次表明, 在中央厨房运营的独特的新环境中, 由于新的设定即每日菜品需求预测直接决定每日容量水平, 需求预测准确度衡量标准有着严重偏差, 长期来讲准确性可能下降, 从而导致次优的商业决策。本研究的主要理论贡献是提供一个餐饮企业在新运营环境中解释和描述需求预测准确度中结构性偏差的全新分析模型。

This study aims to explore whether Chat Generative Pre-training Transformer (ChatGPT) can produce quantitative data sets for researchers who could behave unethically through data fabrication.

A two-stage case study related to the field of tourism was conducted, and ChatGPT (v.3.5.) was asked to respond to the first questionnaire on behalf of 400 participants and the second on behalf of 800 participants. The artificial intelligence (AI)-generated data sets’ quality was statistically tested via descriptive statistics, correlation analysis, exploratory factor analysis, confirmatory factor analysis and Harman's single-factor test.

The results revealed that ChatGPT could respond to the questionnaires as the number of participants at the desired sample size level and could present the generated data sets in a table format ready for analysis. It was also observed that ChatGPT's responses were systematical, and it created a statistically ideal data set. However, it was noted that the data produced high correlations among the observed variables, the measurement model did not achieve sufficient goodness of fit and the issue of common method bias emerged. The conclusion reached is that ChatGPT does not or cannot yet generate data of suitable quality for advanced-level statistical analyses.

This study shows that ChatGPT can provide quantitative data to researchers attempting to fabricate data sets unethically. Therefore, it offers a new and significant argument to the ongoing debates about the unethical use of ChatGPT. Besides, a quantitative data set generated by AI was statistically examined for the first time in this study. The results proved that the data produced by ChatGPT is problematic in certain aspects, shedding light on several points that journal editors should consider during the editorial processes.

本研究旨在探讨ChatGPT是否能够为那些可能通过数据伪造行为不道德的研究人员生成定量数据集。

本研究进行了与旅游领域相关的两阶段案例研究, 并要求ChatGPT（v.3.5.）代表400名参与者回答第一个问卷, 以及代表800名参与者回答第二个问卷。通过描述统计、相关分析、探索性因子分析、验证性因子分析和哈曼的单因素测试对人工智能生成的数据集的质量进行了统计测试。

结果显示, ChatGPT能够按照所需的样本大小水平回答问卷, 并以表格格式呈现生成的数据集, 以便进行分析。还观察到ChatGPT的回答是系统性的, 并且它创建了一个在统计上理想的数据集。然而, 本研究注意到所产生的数据在观察变量之间存在较高的相关性, 测量模型未能达到足够的拟合度, 并出现了共同方法偏差的问题。本研究得出的结论是, ChatGPT目前不能生成适用于高级统计分析的数据, 或者说不适合这样做。

本研究表明, ChatGPT可以为试图不道德地伪造数据集的研究人员提供定量数据。因此, 它为关于ChatGPT不道德使用的持续争论提供了一个新而重要的论点。此外, 在本研究中首次对由人工智能生成的定量数据集进行了统计检验。结果表明, ChatGPT生成的数据在某些方面存在问题, 为期刊编辑在编辑过程中考虑的几个要点提供了启示。

Based on object–object congruity, this study aims to clarify the driving factors and antecedent mechanism of tourists’ willingness to purchase intangible cultural heritage (ICH)-souvenirs.

This study used a five-point Likert scale to collect data and proposed a structural equation model to explore this issue.

ICH-inheritor/souvenir-congruity is positively related to tourists’ purchase intention for ICH-souvenirs and perceived authenticity; perceived authenticity and brand identity play a chain mediating effect between ICH-inheritor/souvenir-congruity and the purchase intention for ICH-souvenirs.

This paper excludes individual, situational and cultural factors, ignoring the possible moderating roles of these factors. This treatment simplifies the feasibility of the present study but might lead to the deviation between the results of the current research and the actual outcomes.

The retailers of ICH-souvenirs should encourage the ICH-inheritors to endorse and promote their products while creating. They could tell a good story about their experience or create entertainment experiences for tourists through hand-in-hand teaching.

This study explores the driving factors and antecedent mechanism of tourists’ purchase intention for ICH-souvenirs from the third perspective of image congruity theory, namely, object–object congruity.

品：形象一致性与品牌对游客购买意向的影响

基于客-客一致性, 本研究旨在厘清游客购买非物质文化遗产纪念品的影响因素与驱动机制。

本研究利用5点式Likert量表收集数据, 并提出了一个结构方程模型来探讨这个问题。

非遗传承人/纪念品一致性正向显著影响非遗纪念品的购买意愿和本真性感知; 本真性感知和品牌认同在非遗传承人/纪念品一致性和非遗纪念品购买意愿之间起着链式中介作用。

本研究从形象一致性理论的第三个视角（客-客一致性）, 探讨了游客购买非遗纪念品的影响因素与驱动机制。

本研究进一步证明了客-客一致性的有效性和合理性, 拓宽了形象一致性理论的外延。

非遗纪念品的零售商应鼓励非遗传承人在创作的同时代言和推广他们的产品。他们可以讲述自己的经历, 或者通过手把手教学为游客创造娱乐体验。

本文排除了个人、情境和文化因素, 忽略了这些因素可能的调节作用。这种处理简化了当前研究的可行性, 但可能导致当前研究结果与实际结果之间的偏差。

la influencia de la consistencia de la imagen y la marca en la intención de compra de los turistas

Resumen

Basado en la congruencia objeto-objeto, el presente estudio busca esclarecer los factores impulsores y el mecanismo antecedente sobre la disposición de los turistas a adquirir recuerdos del PCI.

El presente estudio utiliza una escala de Likert de cinco puntos para recopilar datos y plantea un Modelo de Ecuaciones Estructurales (MEE) para estudiar este asunto.

La congruencia entre el heredero/recuerdo del PCI se relaciona de forma positiva con la intención de compra de recuerdos del PCI por parte de los turistas y con la autenticidad percibida; la autenticidad percibida y la identidad de marca ejercen un efecto mediador en cadena entre la congruencia entre el heredero/recuerdo del PCI y la intención de compra de recuerdos del PCI.

El presente estudio explora el mecanismo antecedente de la intención de compra de los turistas de recuerdos de PCI a partir de la tercera perspectiva de la teoría de congruencia de la imagen (la congruencia objeto-objeto).

El presente estudio justifica la validez y racionalidad de la congruencia objeto-objeto, extendiendo la teoría de la congruencia de imagen.

Los minoristas de los recuerdos del PCI deben fomentar que los herederos del PCI respalden y promocionen sus productos al mismo tiempo que los crean. Ellos pueden contar sus propias experiencias o crear experiencias entretenidas para turistas mediante la enseñanza mediante ejemplos.

El presente documento no tiene en cuenta los factores individuales, situacionales y culturales e ignora el posible papel moderador de estos factores. Dicho tratamiento simplifica la viabilidad de este estudio, aunque podría dar lugar a una desviación entre los resultados de la presente investigación y los resultados reales.

Distance is the core concept in tourism. However, previous studies focused on single distance dimensions and generated contradictory findings due to omitted variable biases. This paper aims to introduce the well-established CAGE (cultural, administrative, geographical, and economic) distance framework into international tourism research to measure the comprehensive distance and explore its impact on inbound tourist satisfaction.

The comprehensive distance was calculated based on the Mahalanobis formula. Combining tourist review data from TripAdvisor, this study used ordinary least square regressions to explore the influence of the comprehensive distance on inbound tourist satisfaction and the mediating role of inbound tourist emotion.

Results show that CAGE distance effectively describes the dynamic change in distance. The comprehensive distance also positively impacts tourist satisfaction, and tourist emotion plays a mediating role in this impact.

This paper advances knowledge about distance in international tourism by introducing the CAGE distance framework and addresses the contradictory findings with specific distance dimensions by the comprehensive distance.

距离是旅游的核心概念。然而, 以前的研究集中在单一的距离维度上, 并且由于遗漏变量偏差而产生了相互矛盾的结果。 本文旨在将成熟的 CAGE 距离框架引入国际旅游研究中, 以衡量综合距离并探讨其对入境游客满意度的影响。

综合距离根据马氏距离公式计算。 结合TripAdvisor网站的游客评论数据, 采用普通最小二乘（OLS）回归分析综合距离对入境游客满意度的影响以及入境游客情绪的中介作用。

结果表明, CAGE距离有效地描述了距离的动态变化。 综合距离也正向影响游客满意度, 游客情绪在此影响中起中介作用。

本文通过引入 CAGE 距离框架来提升国际旅游中的距离知识。 本研究还通过综合距离解决了特定距离维度的矛盾发现。

La distancia es el concepto central en el turismo. Sin embargo, estudios previos se han centrado en dimensiones de una sola distancia, generando resultados contradictorios debido a los sesgos por la omisión de variables. Este trabajo tiene como objetivo introducir el marco de distancia CAGE, establecido en la investigación turística internacional, con la intención de medir la distancia integral y explorar su impacto en la satisfacción del turista receptor.

La distancia integral se calculó con base en la fórmula de Mahalanobis. Combinando los datos de reseñas turísticas de TripAdvisor, se utilizaron regresiones de mínimos cuadrados ordinarios (OLS) para explorar la influencia de la distancia integral en la satisfacción del turista receptor y el papel mediador de la emoción del turista receptor.

Los resultados muestran que el modelo CAGE describe el cambio dinámico en la distancia de una forma efectiva. La distancia integral también impacta positivamente en la satisfacción del turista, y la emoción del turista juega un papel mediador en este impacto.

Este documento avanza en el conocimiento sobre la distancia en el turismo internacional mediante la introducción del marco de distancia CAGE. Además, aborda resultados contradictorios con las dimensiones de distancia específicas mediante la distancia integral.

This study aims to apply the stimulus-organism-response framework to uncover the underlying mechanism by which the perceived helpfulness of online customer reviews (OCRs) drives behavioural intentions in mobile travel app commerce. Also, the current study explores how vendor-driven perceived usefulness of a product and its attributes influence the mediated relationship between perceived helpfulness of OCRs (OCRs helpfulness) and behavioural intentions.

The online survey (n = 151) was used to collect the data. The authors used structural equation modelling and the bias-corrected bootstrap method to test the proposed conceptual model for mediation and moderated-mediation effect.

Findings indicate that the perceived OCRs helpfulness has an indirect positive effect, via trust and attitude, on travel app downloading intention. Moreover, results suggest that the presence of vendor cues (vendor-generated informational content about a travel app) does not significantly moderate the mediating effect of perceived OCRs helpfulness on travel app downloading intention.

The present study reinforces the applicability of the warranting principle in the context of travel app commerce by exploring the relative effectiveness of customer-generated and vendor-generated informational content in influencing travel app downloading intention.

本研究旨在应用SOR框架来解释在线评论的有效性影响在旅行APP行为意向的潜在机理。此外，本研究探索了供应商驱动的对产品的认知有效性和商品属性来影响认知有效性和行为意向的中介关系。

本研究运用网络调研 （n=151）来收集数据。本论文运用结构方程建模和偏差纠正辅助程序来测试提出的理论模型和调节式中介作用。

研究结果显示在线评论的有效性通过信任度和态度对旅行APP的下载使用意向具有间接正相关的作用。此外，结果显示当供应商信息（供应商制定的有关旅行APP的信息内容）并不能有效调节网络顾客评论对下载意向的中介作用。

本研究加强了担保原则在旅行APP贸易背景下的适用性，探索了顾客驱动和供应商驱动的信息内容对旅行APP下载意向影响的相对有效性。

Prior research in tourism and hospitality domain calls for closer attention to model specification when using partial least square-structural equation modeling (PLS-SEM), including the choice of software and algorithm for PLS model estimation. This paper aims to illustrate the significance of choosing appropriate algorithms for testing the nature of relationships by comparing findings using two different PLS-SEM software packages.

Using a field experiment, relationships between visual servicescape aesthetics and affective responses are conceptualized based on literature in environmental psychology and marketing domains. With photographic surrogates as stimuli in two different hospitality service contexts – spa and upscale restaurant – data are collected from 350 respondents.

By comparing results of SmartPLS 3.2 and WarpPLS 5.0 software and theoretical understanding from environmental psychology literature, it is illustrated that the results and their interpretations may not be in line with theory if model specifications are not correctly implemented and are not addressed through usage of software with a relevant algorithm to test them.

The study highlights the implications for model specification issues such as type of variables and nature of relationships that tourism and hospitality researchers often face and also how use of appropriate algorithms can overcome limitations of model testing for complex models and provide empirical rigor to support theory.

本论文使用两种不同的PLS-SEM处理软件来测试理论模型。通过解析模型设定参数问题, 特别是通过结构关系本性分析, 本论文指出选择合适的软件测试模型在酒店旅游领域的PLS研究中是非常关键的。

本论文借助图像拍摄手段采用实验的采样方式, 在两个不同的酒店服务场所—按摩和高档餐厅—搜集350份数据。本论文采用Smart PLS 3.2 和Warp PLS 5.0 软件来测试PLS-SEM。 这两款软件支持线性和非线性理论关系的比较。

通过Smart PLS 3.2 和Warp PLS 5.0 软件得出的报告结果分析, 不同软件处理PLS得出的结果可能有偏差, 而且会不符合理论设定。如果模型设定参数不正确, 通过使用合适的PLS-SEM软件和相关的数据分析加以辅助, 可能会解决参数不正确的问题。

本论文的比较分析结果可能会帮助到酒店和旅游领域的研究者们, 在做对有关PLS-SEM软件选择的时候, 哪些软件可以更加合适的测试模型有着参考意义。

本论文重点指出了模型设定参数的相关问题, 比如旅游酒店领域常见的变量种类和关系属性等。本论文还研究了如何选择合适的数据分析方法来克服测试复杂模型时的限制, 并且提供实践结果来支撑理论。

The purpose of this study is to investigate the concept of vicarious moral cleansing and scrutinize whether unethical behavior of leaders initiate moral cleansing in subordinates or not. This study also highlights a boundary condition under which employees are motivated to cleanse their moral self-image through increased organizational citizenship behaviors and decreased counterproductive work behaviors.

The study is quantitative based on hypothesis testing. By adopting convenience sampling technique, employees working at all managerial levels of service sector organizations were asked to fill out the questionnaires. Being a time-lagged study, data for independent variable (unethical leadership) and moderator (relational self-construal) were collected at T1, data for mediator (moral self-image) were collected at T2 and data for outcomes (OCBs, CWBs) were collected at T3 from same respondents. To rule out the possibility of common method bias and social desirability bias, a multi-wave design was adopted and respondents were asked to provide unique keys/IDs instead of their names.

This study investigated the impact that unethical leaders impose on employee self-concept. Moreover, this study also explored the motivational tendencies of moral self-image. Findings suggest that employees' desirable or undesirable behaviors against leader are dependent upon the perceptions related with their own role, self-image and perception of leader's integrity and intentions. Leader's unethicality is perceived threatening for their own moral self-image and they deal with it constructively. This study has laid the foundation for presence of vicarious moral cleansing in organizational setup, and it is advised that researchers must investigate this phenomenon in different settings to provide useful insights.

Due to lack of resources, employing a pure longitudinal research design was not feasible, and therefore a time-lagged research design was used to gather data from only two cities of Pakistan. However, authors believe that a longitudinal research design, with data collection from a larger sample, will provide more fine-grained results. Secondly, use of perceived leader's integrity scale to measure unethical leadership is another limitation. Although the authors tried to address this issue by conducting an EFA and adopting only suitable items, yet a new scale which is able to measure the true essence of unethical leadership ought to be developed.

Use of moral self-image as an indicator of moral cleansing is an additional contribution of this study, as previous studies used levels of guilt as driving force behind moral cleansing and compensatory cleansing. Most of the studies on unethical leadership as well as moral cleansing took place in the Western context and scholars' stress that culture can substantially influence outcomes of these constructs. Thus, this study extends the literature on moral cleansing and moral self-regulation by developing and testing a model in cultural settings of Pakistan.

本研究擬探討間接感受到的道德清洗 (以下簡稱間接道德清洗) 這個概念；研究亦會仔細審視領袖的不道德行為會否在其下屬間引起道德清洗。就此而言，本研究亦強調了一個邊界條件，在這邊界條件之下，僱員透過組織公民行為的增加，以及為工作目標帶來負面影響的工作行為的減少得到激勵，進而淨化他們的道德自我形象。

本研究為一個基於假設檢定的量性研究；研究採用任意抽樣方法而進行。在服務業機構內不同管理階層工作的僱員被邀回答問卷；由於這是一個時滯研究，即使是同一的答覆者，IV (不道德的領導) 和仲裁人(關係型自我建構)的數據在T1收集，調解員 (道德自我形象) 的數據在T2收集，結果 (OCBs，CWBs) 的數據在T3收集，為了排除共同方法偏差和社會期許誤差的出現，研究採用多波浪設計，而且，答覆者必須提供獨一無二的密鑰或身份證明，而不是提供他們的名字。

本研究探討了不道德的領袖對僱員自我概念的影響；研究亦探索了可能推動道德自我形象的因素。研究結果暗示、僱員會做對領袖而言可取的行為與否，全視乎他們如何看待自己的角色和自我形象，也視乎他們對領袖的誠信和動機有甚麼看法。領袖若不道德，這會被認為會對僱員的道德自我形象做成威脅，在這情況下，僱員會積極地應付這個威脅。本研究為在組織架構內存有間接道德清洗這個觀點打下基礎。今後的研究學者或許應就不同的環境、對這個現象進行探討和研究，以使我們能更深刻地瞭解這個課題。

從前的研究均採用內疚的程度、作為道德清洗和補償清洗背後的推動力 (Liao et al., 2018) 。本研究另外的貢獻在於採用了道德自我形象、作為道德清洗的指標。以前關於不道德領導以及道德清洗的研究，大多以西方國家為背景。研究學者均強調文化因素會很大程度地影響這些觀念帶來的結果；因此，本研究透過設計一個以巴基斯坦文化為背景的模型、並對其進行測試、來擴展有關道德清洗及道德自我調節的文獻。

This study examines the causal relationship between exports and economic growth in sub-Saharan African (SSA) countries during the period 1980 to 2017. The study also examines whether the causality between these two macroeconomic variables depends on the countries' stage of development as proxied by their per capita income.

The study uses a panel cointegration test and panel Granger-causality model to examine the link between exports and growth. The study also incorporates external debt as an intermittent variable in a bivariate setting between exports and economic growth, thereby creating a dynamic multivariate panel Granger-causality model.

Although the study found the existence of a long-run relationship between exports and economic growth, the study failed to find any export-led growth response in both low-income and middle-income countries. Instead, the study found evidence of a bidirectional causality and a neutrality response in middle-income and low-income countries, respectively. The study, therefore, concludes that the benefits of an export-led growth hypothesis may have been oversold, and that the strategy may not be desirable to some low-income developing countries.

These findings have important policy implications as they indicate that the causality between exports and economic growth in SSA countries varies with the countries' stage of development. Consistent with the contemporary literature, the study cautions low-income SSA countries against over-relying on an export-led growth strategy to achieve a sustained growth path as no causality between exports and economic growth has been found to exist in those countries. Instead, such countries should consider pursuing new growth strategies by building the domestic demand side of their economies alongside their export promotion strategies in order to expand the real sector of their economies. For middle-income countries, the study recommends that both export promotion strategies and pro-growth policies should be intensified as economic growth and exports have been found to reinforce each other in those countries.

Unlike the previous studies, the current study disaggregated the full sample of SSA countries into two subsets – one comprising of low-income countries and the other consisting of middle-income countries. In addition, the study uses a multivariate Granger-causality model in order to address the emission-of-variable bias. To our knowledge, this may be the first study of its kind in recent years to examine in detail the causal relationship between exports and economic growth in SSA countries using an ECM-based multivariate panel Granger-causality model.

本研究旨在探討在1980年至2017年期間撒哈拉以南非洲國家的出口、與其經濟增長之間的因果關係，亦探討這兩個宏觀經濟變量之間的因果關係、會否取決於有關國家所處以人均收入來衡量的發展階段。

本研究雖然發現出口與經濟增長存有一個長期性關係，唯未能於低收入國家或中等收入國家、找到任何出口帶動的增長反應。研究反而找到證據，證實中等收入國家為一雙向性因果關係反應，而低收入國家則為一中立性反應。因此，研究的結論是：出口必能帶動經濟增長這假設被過度吹噓，而且，對部份低收入發展中國家而言，實施以出口帶動經濟增長的策略或許是沒有用的。

本研究的結果在政策方面有其重要意義。這是因為研究結果顯示、於撒哈拉以南非洲國家、出口與經濟增長之間的因果關係，會因有關國家所處的發展階段而有所變更。與當代文獻一樣，本研究提醒低收入的撒哈拉以南非洲國家，不要過度依賴以出口帶動增長的策略來謀求踏上持續增長之路，這是因為在這些國家，出口與經濟增長之間的因果關係仍未確立。他們反而應考慮推行新增長經濟策略，方法是在實施推動出口的策略的同時，也要建立其經濟的國內需求面，以擴大其經濟實業部門。就中等收入國家而言，本研究建議他們應增強推動出口的策略及強化促進增長的政策，這是因為在這些國家裏，經濟增長及出口已被證實會互為增強。

有別於過去的研究，本研究把撒哈拉以南非洲國家的整體樣本分解為兩個子集：一個包括低收入國家，另一個則包括中等收入國家。而且、研究使用了多變量面板格蘭傑因果關係模型、以處理遺漏變數偏差的問題。據我們了解，這大概是近年首個同類研究、以基於歐洲共同市場多變量面板格蘭傑因果關係模型、來詳細探討於撒哈拉以南非洲國家、出口與經濟增長之間的因果關係。

This study aims to examine the relationships among the dimensions of consumption values (functional, social and emotional), co-creation, information overload, satisfaction and continuance intention derived from the use of the Airbnb platform.

A Web-based survey was conducted among Italians, and a valid sample of 259 persons was obtained for data analysis.

The survey results indicated that only functional value and social value are strong predictors of satisfaction in the use of the Airbnb website for accommodation booking. Co-creation and absence of information overload also contribute to satisfaction with using the Airbnb website for accommodation booking, which in turn affects continuance intention.

The findings of this study are highly destination-specific, given that the authors collected the data only from Italian residents. The sample was based on a snowball sampling technique; thus, the study findings could be misrepresented because of sampling selection bias. Moreover, the study was limited to the use of three dimensions of consumption values, co-creation, information overload and satisfaction to predict continuance intention. Furthermore, the present study adopted a Web-based survey questionnaire.

Managerial implications include recommendations for hosts to emphasise their prices when listing accommodations on the Airbnb website and to focus on active interaction with potential guests. Information on the website should also be organised to avoid information overload.

This study allows a deeper understanding of users’ continuance intention with regards to the Airbnb website by exploring the possible determinants.

本研究考察了消费价值（功能、社会和情感方面）、共同创造、信息超载、满意度与Airbnb平台持续参与使用之间的关系。

研究对意大利人进行了网上调查, 得到了259份有效的抽样数据并进行分析。

调查结果显示, 只有功能价值和社会价值才能强烈预测Airbnb网站住宿预订的满意度。共同创造和信息不超载也有助于使用Airbnb网站进行住宿预订的满意度, 这又会影响网站的持续参与使用。

这项研究的结果受地域限制, 因为我们只收集了意大利居民的数据。该样本基于滚雪球采样技术, 因此, 由于抽样选择偏差, 研究结果可能被歪曲。该研究还仅限于使用消费价值、共同创造、信息超载和满意度三个维度来预测持续参与使用。此外, 网上调查问卷的发放也可能会影响问卷的质量。

本研究的管理意义包括建议房东在Airbnb网站上列出住宿时强调价格, 并专注于与潜在客人的积极互动。房东还应组织网站上的信息, 以避免信息超载。

这项研究通过探索可能的决定因素, 更深入地了解用户对Airbnb网站的持续参与使用。

Este estudio examina las relaciones entre las dimensiones de los valores de consumo (funcional, social y emocional), co-creación, sobrecarga de información, satisfacción e intención de continuidad, derivada del uso de la plataforma Airbnb.

Se realizó una encuesta “en línea”, entre italianos, y se obtuvo para el análisis de datos, una muestra válida de 259 personas.

Los resultados de la encuesta indicaron, que solo el valor funcional y el valor social, son fuertes predictores de la satisfacción en el uso del sitio web de Airbnb a la hora de hacer reservas de alojamiento. La creación conjunta y la ausencia de sobrecarga de información, también contribuyen a la satisfacción de usar el sitio web de Airbnb, para reservar alojamiento, lo que a su vez afecta la intención de continuidad.

Los resultados de este estudio son específicos para un destino, dado que la recolección de los los datos solo se efectúo sobre residentes italianos. La muestra final, se obtuvo con una técnica de muestreo de bolas de nieve; por lo tanto, los resultados del estudio podrían tergiversarse debido al sesgo de selección de muestreo. Además, el estudio se limitó al uso de tres dimensiones de valores de consumo, co-creación, sobrecarga de información y satisfacción para predecir la intención de continuidad. Además, el presente estudio adoptó un cuestionario de encuesta basado en la web.

Las implicaciones gerenciales incluyen recomendaciones para que los anfitriones resalten sus precios, al enumerar alojamientos de Airbnb y centrarse en la interacción activa con posibles huéspedes. La información en el sitio web también debe organizarse para evitar la sobrecarga de información.

Este estudio permite una comprensión más profunda sobre la intención de continuidad de los usuarios con respecto al sitio web de Airbnb, al explorar los posibles determinantes que la afectan.

The high-speed rail network can lead to the transformation of the tourism industry, as well as the regional economy. In the present study, a reasonable method was developed to assess the contributions of high-speed rail network to the development of tourism and economy in a Chinese region known as the “1 + 8” city tourism circle.

The method proposed here combines not only tourism revenue but also regional economy in a MGM (1, n) gray model, and it studies the tourist and economic output of this tourism circle before and after the high-speed rail network’s construction using an advanced “with and without comparison” method.

By using this method, the accuracy of the prediction of the contribution rate of high-speed rail network is improved. We found that in the “1 + 8” city tourism circle, the high-speed rail network positively contributes to increase of the tourism arrival and tourism revenue. Furthermore, regional economy significantly grows under the impact of the high-speed rail network.

The “1 + 8” city tourism circle is studied as a closed system in this paper, and the authors focus on the economic associations between the cities in the circle by ignoring the impact from outside this circle. This treatment means, simplifies and enables the feasibility of this study, but it virtually leads to the deviation of outcomes between this study and the practical.

For theoretical values, by studying a normal Chinese inland region, this study reconfirmed the positive impact of high-speed railway empirically. In the meantime, this study developed an improved method by introducing gray theory models to “with and without comparison” method to calculate the contribution of high-speed railway to the regional tourism and economy development. Such method simultaneously incorporates the indexes of regional tourism income and regional GDP simultaneously. It is direct and convenient as it can achieve accuracy requirements using only a small amount of data, and it reconciles more with reality by considering the interaction of the outcomes of tourism and economy.

For practical values, using the proposed method, a direct and convenient calculation of the contributions of high-speed railway to many other regions can be achieved if the data of the outcomes of tourism and economy can be obtained. In such a way, the regions that really need high-speed railway to stimulate their development can be distinguished from regions whose high-speed railway is under blind construction. Thus, the government may take actions to reassess some uneconomic high-speed railway projects without discouraging the construction of high-speed railway in other regions. The authors believe that this is important not only for China but also for many other countries with high-speed railway projects.

This study develops a reasonable method of assessing the contribution of high-speed rail to regional tourism and economic development. Using this method, this study confirmed that high-speed rail indeed positively impacts the regional development.

抽象

高速铁路（HSR）网络可以带动旅游业乃至区域经济的转型。本研究构建了一个合理的方法来评估高铁网络对中国 “1+8” 城市旅游圈的旅游产业和区域经济发展的贡献。

本文提出的方法将旅游收入和区域经济的指标结合在一个MGM（1，n）灰色模型中，并采用先进的 “有无比较法” 来研究高铁网建设前后该旅游圈的旅游和经济产出。

利用该方法，可更精准地预测高速铁路网的贡献率。研究发现，在“1+8” 城市旅游圈中，高铁网络对游客到访量和旅游收入的增加起到了积极的促进作用。此外，在高铁网络的影响下，区域经济得到了显著增长。

本文将 “1+8” 城市旅游圈作为一个封闭的系统进行研究，忽略了外部因素的影响，而重点研究旅游圈内城市之间的经济联系。这种处理方法简化了本研究的过程，增加了研究的可行性，但实际上导致了本研究结果与现实存在偏差。

就理论上而言，本文通过对一个典型的中国内陆地区展开研究，从经验上重新确认了高速铁路的积极影响。同时，将灰色理论模型引入到“有无比较法” 中，提出了一种改进方法，用以计算高速铁路对区域旅游业和经济发展的贡献。该方法同时结合了区域旅游收入和GDP指标，十分直接方便，只需要少量数据就可以达到准确的要求；并且由于它考虑到了旅游业和经济的相互作用，更符合实际。

就实用价值而言，只需获得旅游业和经济成果的数据，即可利用该方法直接方便地计算高铁对众多其他地区的贡献。这样一来，就可以将真正需要高铁来刺激发展的地区与盲目建设高铁的地区区分开来。由此，政府可以对一些不经济的高速铁路项目进行重新评估，而不妨碍其他地区的高铁建设。笔者认为，这对中国乃至其他许多国家的高铁项目建设来说是很重要的。

本研究提出了一种合理的方法来评价高铁对区域旅游业和经济发展的贡献。利用这一方法，本研究证实了高铁确实对区域发展产生了积极的影响。

Resumen

La red de ferrocarril de alta velocidad (HSR) puede liderar la transformación de la industria turística, así como la economía regional. En el presente estudio, se ha desarrollado un método para evaluar las contribuciones de la red ferroviaria de alta velocidad, en el desarrollo económico en una región China conocida como el círculo de turismo urbano “1+8”.

El método que se propone combina, no solamente los ingresos por turismo, sino también la economía regional en un modelo MGM (1,n) gris, y estudia la producción turística y económica de este círculo turístico, antes y después de las construcción de la red ferroviaria de alta velocidad utilizando un método “con y sin comparación”.

Usando este método, se mejora la predicción de la tasa de contribución de la red de alta velocidad. Nosotros descubrimos que en el círculo “1+8”, la red ferroviaria de alta velocidad contribuye positivamente al aumento en la llegadas de turistas y los ingresos por turismo. Además, la economía regional, crece significativamente bajo el impacto de esta red.

En este artículo, el círculo de turismo urbano “1+8”, se estudia como un sistema cerrado, se enfoca en la asociación económica entre las ciudades, pero ignorando el impacto desde fuera. Este tratamiento significa simplificar y habilitar la viabilidad de este estudio, pero prácticamente conduce a la desviación de los resultados entre este estudio y la practica.

El valor teórico, estudiando una región normal del interior de China, reconfirma el impacto positivo del ferrocarril de alta velocidad. Mientras tanto, este estudio desarrolla un método mejorado, introduciendo los modelos de “teoría gris” en los métodos “con y sin comparación”, para el calculo de la contribución del ferrocarril de alta velocidad en el desarrollo de la economía regional y turística. Además y simultáneamente, el método incorpora los índices de ingresos del turismo regional y el PIB. Esto es directo y conveniente, ya que puede cumplir con los requisitos de precisión, usando solamente una pequeña cantidad de datos, y concilia más con la realidad considerando la interacción del resultado del turismo y economía.

Para los valores prácticos, usando el modelo propuesto, se puede lograr un cálculo directo y conveniente de las contribuciones del ferrocarril de alta velocidad a muchas otras regiones, y se pueden obtener datos del impacto del turismo y la economía. De esta manera, las regiones que realmente necesiten el ferrocarril de alta velocidad para estimular su desarrollo, se podrán diferenciar de aquellas otras que lo planteen a ciegas. Por lo tanto, los gobiernos deberían tomar acciones para reevaluar algunos proyectos ferroviarios de alta velocidad ineficientes, sin desalentar la construcción de los mismos en otras regiones. Los autores creen que esto no sólo es importante para China, sino también para muchos otros países con proyectos de ferrocarriles de alta velocidad.

Este estudio desarrolla un método razonable de evaluación de la contribución del ferrocarril de alta velocidad, en el desarrollo de la economías regionales y turísticas. Usando este método, este estudio confirma que el ferrocarril de alta velocidad añade impactos positivos en el desarrollo regional.
