反倾销的跨国实证分析——基于宏观经济因素对反倾销立案影响的理解

本文基于15个国家1995－2004年反倾销的统计数据,通过模型分析以及实证研究,表明宏观经济因素对反倾销立案存在显著影响。文章依据GDP增长率、失业率、汇率及经常项目差额等相关数据,指出这些变量与反倾销立案数量显著相关,强调失业率的影响比GDP增长率更加显著。在发展中国家中,汇率对反倾销立案数量影响的显著性较低,而经常项目差额对反倾销立案数量影响的显著性较高。本文的分析在一定程度上给政府制定反倾销政策提供了相关参考价值。     

Developing a spatial planning information package in ISO 19152 land administration domain model

Cities establish and maintain Land Administration Systems (LAS) to manage information about the land and urban space. Recognizing the importance of the urban space for sustainable development, information from spatial planning will affect land administration and vice versa. Therefore, every aspect that influences land use, both from spatial planning and land administration should be identified, documented, and standardized as they contain legally binding rules for governments and citizens. The Land Administration Domain Model (LADM), ISO standard 19152:2012, offers guidelines to ensure interoperability in the representation of Rights, Restrictions, and Responsibilities (RRRs). LADM is also capable of standardizing multi-dimensional representation, including the temporal capability for documenting and visualizing all legal aspects of land use or space. This paper discusses how to construct interoperable information between the spatial plan and land administration. We present the standardization of spatial planning information and land administration as subsets of land-related information. The paper proposes the development of a spatial planning package within the existing LADM standard.     

商业模式创新构念化研究回顾与理论构建：基于组合模型视角

诸多学者强调应加强商业模式创新概念研究，但真正意义上的概念解构研究却很少，使得理论界对于将商业模式创新视为构念依然存在颇多质疑。通过比较分析不同测量模型用于解构商业模式创新概念的适用程度，确立组合模型的高适用性地位，同时从理论层面详细探讨该模型视角下商业模式创新的定义、维度和类型。进一步地，综合考虑商业模式双重属性特征，以及商业模式与其它学科领域的内容交叉性，分析组合模型视角下商业模式创新测量指标构建方向。最后，构建组合模型视角下商业模式创新的构念化路径。具体来说，采用“经营方式创新+创造独特顾客价值”形式定义概念，以创造独特顾客价值为标准区分维度，进而综合经营框架与价值逻辑两种属性研究的测量指标开发量表；明确降低购买价格和提升支付意愿维度的内涵，广泛借鉴战略、营销及生产运营等领域知识，开发两个维度的测量量表。     

Introducing a three‐tier sustainability framework to examine bike‐sharing system use: An extension of the technology acceptance model

There is growing interest among the general public and researchers in the sharing economy, because of its profound impact on individuals, businesses and governments today. A particular kind of the sharing economy is bike‐sharing systems which provide benefits for users, societies and the environment, suggesting sustainability could play an important role in their use. With this in mind, the purpose of this paper is to examine bike‐sharing users through a three‐tier framework, where sustainability is considered at multiple tiers, that is, micro (personality), mezzo (relations) and macro (system) tiers. In line with this proposition, the conceptual model is an extension of the Technology Acceptance Model (TAM), representing factors at the macro tier, that is, perceived sustainable usefulness and ease‐of‐use, influenced by bike quality. The effect of sustainable subjective norms on loyalty plays out at the mezzo tier, while sustainable extraversion is linked to loyalty at the micro tier. The model was tested on a sample of bike‐sharing system users. The results show that bike quality positively influences perceived sustainable usefulness, but not ease‐of‐use; however, ease‐of‐use positively influences loyalty among users, while usefulness does not. In addition, sustainable subjective norms and sustainable extraversion have a significant positive effect on user bike‐sharing system loyalty. The findings offer a range of implications for the providers of bike‐sharing systems, municipalities and governments which are promoting alternative means of transportation to reduce the carbon footprint.     

Entrepreneurship,institutions and skills in low-income countries

This paper develops a model of costly firm creation in an economy with weak institutions, costly business environment as well as skill gaps where one of the equilibrium outcomes is a low-productivity trap. The paper tests the implications of the model using a cross-sectional dataset including about 100 countries. Both theoretical and empirical results suggest that to move the economy into a productive equilibrium, complementarity matters: reforms to improve the business environment tend to be more effective in creating productive firms when accompanied by narrowing skill gaps. Similarly, more conducive business regulations amplify the positive impact on firm creation of better education and reduced skill mismatches. To escape a low-productivity trap, policymakers should thus create a pro-business framework and a well-functioning education system.     

Using information quality for volatility model combinations

This paper proposes updated methodology for volatility model combinations which account for the informational content of innovations. An adaptive measure of information quality serves for the selection of model weights in order to improve daily volatility forecasts. The information quality proxy is related to the size of unexpected shocks in the volatility process. Our approach is illustrated in an empirical study with German stock market data.     

Volunteer Tourism and Intercultural Sensitivity: The Role of Interaction with Host Communities

This research introduced the concept of intercultural sensitivity to investigate the relationships between the context of volunteer tourism and the change in intercultural sensitivity, empirically assessing the supposition that volunteer tourism facilitates cross-cultural understanding. As a theoretical backdrop, the study utilized Developmental Model of Intercultural Sensitivity (DMIS) postulating that one’s journey towards greater intercultural sensitivity consists of six consecutive stages along the enthnocentrism–ethnorelativism continuum. Canonical correlation analysis of the survey data revealed that quality of interaction with the host community was the most significant predictor of change in intercultural sensitivity. Additionally, this study demonstrated that volunteer tourism is linked to positive and negative changes in intercultural sensitivity and therefore has the potential to simultaneously promote and inhibit cross-cultural understanding.     

Airline passengers’ continuance intention towards online check-in services: The role of personal innovativeness and subjective knowledge

This study integrates the individual psychology constructs (personal innovativeness and subjective knowledge) with the Technology Acceptance Model to develop and test a model of airline passengers’ continuance intention towards online flight check-in services. Predictions were tested with data from a sample of airline passengers in China who have experienced the online check-in service. The findings of this study demonstrate that airline passengers’ innovativeness and subjective knowledge have a direct effect on continuance intention, and an indirect effect through partial mediation of perceived ease of use and perceived usefulness. Theoretical and managerial implications are discussed.     

基于演化博弈模型的产业集群式转移条件及政策适配性研究

集群式产业转移是有限理性的企业在产业转移过程中的合作,是群体决策、调整及决策稳定的过程。基于演化博弈模型,针对自由市场和引入政府干预两种情形下集群式产业转移条件的研究表明,在产业集群式转移过程中,下游企业复制动态演化博弈存在唯一的均衡策略;而上游企业复制动态演化博弈存在两个稳定均衡策略,既有可能收敛于全部转移,也有可能收敛于全部不转移。政府补贴或者惩罚虽不能确保集群式产业转移,但加大了产业集群式转移成功的概率,但在实践中应正确把握承接地政府补贴和转出地政府惩罚的"度"的问题。     

Arithmetic variance swaps

Biases in standard variance swap rates (VSRs) can induce substantial deviations below market rates. Defining realized variance as the sum of squared price (not log-price) changes yields an ‘arithmetic’ variance swap with no such biases. Its fair value has advantages over the standard VSR: no discrete monitoring or jump biases; and the same value applies for any monitoring frequency, even irregular monitoring and to any underlying, including those taking zero or negative values. We derive the fair value for the arithmetic variance swap and compare it with the standard VSR by: analysing errors introduced by interpolation and integration techniques; numerical experiments for approximation accuracy; and using 23 years of FTSE 100 options data to explore the empirical properties of arithmetic variance (and higher moment) swaps. The FTSE 100 variance risk has a strong negative correlation with the implied third moment, which can be captured using a higher moment arithmetic swap.
