技术贸易壁垒下中美纺织品贸易竞争力及影响因素研究

采用国际市场占有率、显性比较优势指数及贸易互补性指数分析了中美两国纺织品在国际市场中的竞争地位及各纺织品类贸易互补性强度,并将美国发布的纺织行业技术通报(TBT)作为技术变量纳入随机前沿引力模型,进一步实证分析中美纺织品贸易的影响因素。结果表明:中国纺织品国际竞争优势强于美国,尤其表现在纺织制成品类;出口角度看,两国在纺织制成品类上呈现显著贸易互补性,进口角度看,两国在纺织原料上具有较强互补性。在影响因素中,技术壁垒、进口国经济、出口国人口及两国距离负向抑制中美纺织品贸易,出口国经济、进口国人口及人均收入之差正向促进中美纺织贸易发展。     

The negative spillover effect of food crises on restaurant firms: Did Jack in the Box really recover from an E. coli scare?

Despite the enormous impact of food crises on restaurants, limited understanding of their long-term impacts and associated factors has undermined crisis managers’ ability to handle crisis situations effectively. This article investigated the long-term impact of food crises on the financial performance of restaurant firms and identified the factors that influenced this impact. This explanatory study examined the case of Jack in the Box, whose 1993 Escherichia coli scare was the first and largest restaurant-associated food crisis in modern times. An event study method was used to uncover stock price movements of Jack in the Box, in conjunction with 73 unrelated food crises that occurred from 1994 to 2010. Stock prices of Jack in the Box exhibited significantly negative responses to other firms’ food crises, moreover, the negative spillover effect was stronger if the crisis occurred closer in time, was similar in nature, and was accompanied with no recall execution. These findings shed light on the long-term financial impact of food crises and offer insights for crisis managers to develop more effective crisis management strategies.     

To go or not to go: travel constraints and attractiveness of travel affecting outbound Chinese tourists to Japan

The fast growth of the Chinese economy has transformed Chinese outbound tourism into one of the major players in the tourism industry worldwide. However, Chinese outbound tourists may still encounter travel constraints in some countries, such as Japan, which has had a close and complicated relationship in history with China. This study adopted the qualitative approach by applying focus group and in-depth interviews to investigate and triangulate the travel barriers affecting Chinese outbound travel to Japan. The findings indicated that domestic nationalist sentiment played a key constraining role in influencing Chinese outbound travel decision-making, followed by current political factors, while quality products and service, as well as social environment encouraged tourists to travel. This research also found that visitors and non-visitors have perception differences in terms of travel barriers and attractiveness of travel.     

产业分工、国际贸易摩擦及我国的对策——基于价值链视角的研究

国际分工格局的改变引致国际贸易格局随之改变,发达国家为持续占领和控制国际分工的主动权,必然采取保护相关措施抑制发展中国家急速扩展的国际贸易业务,进而减弱发展中国家在全球价值链分工体系中的位置,这就必然导致国际贸易摩擦事件频发。基于经济学视角,为了顺利推进我国开放型发展战略的实施,减缓我国国际贸易摩擦的困扰,未来应从内部层面继续加快中国开放型经济转型升级的步伐,创新对内对外的开放模式;从外部层面加速价值链升级工程建设,提升我国在全球价值链分工体系中的地位,逐渐摆脱贸易摩擦的被动地位。     

乡村生态旅游促进新型城镇化的实证分析--以西安市长安区为例

在生态资源富集又邻近大城市的乡村地区发展乡村生态旅游,能够有效地促进新型城镇化、助推新型旅游小城镇的形成。文章在界定核心概念并进行理论机理分析的基础上,以西安市长安区为例,对其2002—2014年间乡村生态旅游与新型城镇化之间的关系进行实证检验,结果表明：二者确实存在高度的正相关关系,且前者是后者的重要原因。因此,应采取有力措施发展这些地区的乡村生态旅游：第一,进一步加大政府对乡村地区基础设施的投资,彻底实现城乡公共产品供给的均等化;第二,引导民间资金、技术、管理等有序合理、规模适度地投入乡村生态旅游业;第三,务必加强乡村生态旅游业发展过程中的环境监管等。     

Quality of service and segmentation in the MICE industry: An approximation based on fuzzy logic

This article aims to evaluate the service quality experienced at academic conferences held at the Universidad Técnica Particular de Loja in Ecuador. Our approach is based on fuzzy logic and ideal solutions to calculate a global attendee satisfaction index for specific market segments: Gender, nationality, and age. Current literature on the service quality experienced by conference attendees is still scarce. Our results show that the analyzed segments experience varying levels of satisfaction, and that the more influential attributes to each of them are also different. Our results can be applied to improve the competitiveness of Loja and that of Universidad Técnica Particular de Loja.

Money secrets: How does trade secret legal protection affect firm market value? Evidence from the uniform trade secret act

Research summary : We investigate the impact of trade secret legal protection on firm market value in the context of acquisitions. On one hand, market value may increase because trade secret assets become better protected from rivals. On the other hand, market value may decrease because trade secret protection reduces information about the target and its competitors available to potential buyers, increasing uncertainty about its value. Buyers will discount their offers in expectation of being compensated for riskier deals. Using a sample of private equity investments in the United States, we find that trade secret protection has a positive effect in industries with high mobility of knowledge workers, but a negative effect in industries with (1) high resource–value uncertainty and (2) high poor‐investment risk. Managerial summary : We argue that an increase in trade secret legal protection might not unequivocally benefit firm owners when selling their business. A stronger trade secret protection increases the market value of firms in industries with high workers' mobility, but it decreases the market value of firms in industries with uncertain resource value and/or high risk of poor‐acquisition investments. Based on the contingent effect of trade secret protection, companies may want to adjust their strategic decisions, including where to locate or relocate, based in part on whether they will derive benefits or suffer losses when trade secrets are better protected. Finally, our study should help policymakers understand more fully the economic impact of government policies associated with trade secrets. Copyright © 2016 John Wiley & Sons, Ltd.
