基于网络外部性的价值模块整合与兼容性选择

本文分析了价值模块的网络外部性特征，并基于网络外部性研究了价值模块整合过程中的兼容性选择和价格竞争行为。研究结果表明：当由进入厂商选择兼容度时，兼容性越高进入厂商的市场份额越大，并能够获得更高的市场价格；当由在位厂商选择兼容度时，兼容度增加将减少消费者的转移成本，使更多的模块需求商转向购买进入厂商的产品，减少了在位厂商的市场份额；当转移成本的兼容性敏感系数较低时，在位模块供应商能够获得更高的价格，而当转移成本对兼容性很敏感时，较高的兼容度将迫使在位模块供应商降低价格。价值模块的网络外部性加剧了模块供应商之间的竞争，进一步促进了价值模块整合和产业融合的过程。     

珠三角OEM企业持续成长的路径选择--基于全球价值链外包体系的视角

OEM企业是珠三角区域新型工业化的重要力量，其持续成长有利于提高珠三角产业国际竞争力。我们分析了OEM企业成长与全球价值链外包体系的动态演变．并归纳出全球价值链外包体系中的OEM企业的一般成长路径。我们将珠三角OEM企业划分为两大阵营，分别探讨了企业实现持续成长的路径选择：第一阵营主动承接价值链高端环节，一部分企业从OEM向ODM转变，另一些则走OEM与OBM相结合的成长模式．也鼓励大企业适当的相关多元化；第二阵营要“做大”OEM，实现规模经济，并向配套产业的方向发展。OEM企业持续成长还要有一个良好的外生环境，主要包括发展机遇、制度环境和文化环境等。     

Financial Stress Regimes and the Macroeconomy

Some financial stress events lead to macroeconomic downturns, while others appear to be isolated to financial markets. We identify financial stress regimes using a model that explicitly links financial variables to macro‐economic outcomes. The stress regimes are identified using an unbalanced panel of financial variables with an embedded method for variable selection. Our identified stress regimes are associated with corporate credit tightening and with NBER recessions. An exogenous deterioration in our financial conditions index has strong negative effects in economic activity, and negative amplification effects on inflation in the stress regime. These results are obtained with a novel factor‐augmented vector autoregressive model with smooth‐transition regimes (FASTVAR).     

Barriers to the “key supplierization” of the firm

The phenomenon of key supply management (KSM) in business companies is far less investigated than the phenomenon of key account management (KAM) which beneficiates, both in practice and in an academic context, from a growing interest. This article is based on the empirical analysis of a sample of 10 international companies which have recently launched KSM programmes or are currently working on launching such programs. It examines the difficulties these companies come up against when implementing such programmes and proposes to organize these difficulties around three dimensions: 1) the difficulties in implementing real supplier portfolio approaches; 2) the narrow view of value co-creation with suppliers, and 3) the persistent lack of integration of the purchasing function with other internal functions within the company. The conclusion of the article is that KSM is far from being a mere symmetric phenomenon of KAM. Several implications are then discussed in relation to the implementation of KSM programmes within companies.

Revisiting Attributes: How Important Is Green in the Consumer Selection of Hotel Rooms?

Consumers’ buying behavior is not always consistent with their positive attitude, particularly toward environmentally friendly products. In a survey of 197 travelers, the relative importance consumers ascribe to the attribute of green was assessed. Through a multi-methods study involving interviews, focus groups discussions, and forced-choice experiments that simulate market buying situation, it was found that consumers’ selection of hotel rooms is still much dictated by traditional choice factors. Through a conjoint analysis, it was found that consumers highly prioritized the price attribute. The green attribute was assigned a low relative importance of 4% among the respondents. Managerial and theoretical implications are discussed.     

Perceptions of determinants of job selection in the hospitality and tourism industry: The case of Korean university students

ABSTRACT

This study explores the key factors influencing potential employees in the hospitality and tourism industry and examines whether causal relationships between behavioral attitudes, subjective norms, and perceived behavioral control influence students' job selection. The study suggests that the career decision-making process is related to job selection. A total of 307 responses were analyzed. The results explain individual students' attitudes toward a behavior and perceived behavioral control in the context of their job selection. Attitudes toward a behavior and job selection had significant effects on career decisions. On the other hand, opinions of significant others had no significant effect. Perceived behaviors required to decide on jobs had a significant effect on job selection intentions. Students with internship experience were likely to form positive attitudes toward the hospitality and tourism industry, suggesting internships to be a useful source of a stronger relationship between the industry and job aptitudes of students in hospitality and tourism programs. The results have important implications.     

中国OFDI区位选择决定因素研究——基于2003-2014年28个经济体面板数据

在国别差异视角下选取2003-2014年28个主要国家和地区的面板数据，并将所有样本国家分为发达经济体和发展中经济体两类，借助于投资引力模型重点考察了东道国市场因素、资源禀赋因素和技术因素对我国对外直接投资区位选择的影响，研究发现，我国OFDI区位选择呈现出明显的国别差异，对发达经济体的投资同时受到市场规模因素和技术禀赋因素的影响，对发展中经济体的投资同时受到市场规模因素和资源禀赋因素的影响，另外还发现随着技术水平的提升和运输工具的革新，距离不再是我国OFDI区位选择的决定因素。     

GIS as a tool for selection of sample areas in a travel behaviour survey

Whilst Geographical Information Systems (GIS) are now used more commonly in transport research and modelling, GIS techniques were used in this study to select similar sample areas (in terms of geography and census attributes) for data collection. For this purpose, a GIS mapping system for Tyne and Wear, UK, was built. The system included topographic maps of the area, boundary maps of Lower Super Output Areas (LSOA), and aggregated census statistics datasets for LSOAs. Criteria relating to census attributes and the nature of transport were employed to identify ‘hotspots’ by GIS enquiry to provide suitably matching areas, which then formed the basis of the sampling frame.The research project was concerned with commuters’ travel choices and so the study needed to identify commuters. In this case-study context, it is not possible to select fully homogeneous areas, so the GIS ‘hotspots’ approach allowed the identification of areas where there were a high concentration of commuters with multiple alternatives for travel to work. A pilot study showed that the GIS origin-based approach was good in collecting a balanced sample, as compared to an employment-based destination survey. This paper explores the benefits and costs of these origin- and destination-based approaches. In the origin-based home sample, households with paper-based surveys were targeted after identification by GIS. This origin approach requires more data preparation compared to the alternative of an employer-based, destination-based sample that could use online survey methodologies.The paper concludes by identifying GIS as an important tool in selecting a sample area for data collection using multiple criteria, but argues that plans for data collection need to be flexibly constructed to overcome unexpected challenges. Although this paper focuses on a transport research case study, the methodology presented can be applied to survey design and selection of sample areas in other disciplines.
