2011年世界船舶市场评述与未来展望

在"增长放缓、风险增大"的2011年全球经济环境下,世界航运市场受"运力投放无休、运营成本增加"的影响而表现为"低迷不振"。新船的不断交付也使世界商船队年轻化势不可挡。新船建造市场同比有所下滑,液货船和散货船表现不佳,集装箱船和海工市场表现较好,新船价格呈现小幅下调趋势。预计2012年世界船市在三大主力船型上仍不容乐观,海工市场继续有尚佳表现。     

Air transport and economic growth: a review of the impact mechanism and causal relationships

ABSTRACT

The impacts of air transport on the economy arise both directly, via activity in the aviation sector; and indirectly, via increased spending and wider economic benefits associated with improved access to resources, markets, technology and economic mass. Economic activity, in turn, supports and generates demand for air transport. Despite its potential importance, the reciprocal nature of the causal relationship between air transport and economic performance has remained somewhat understudied. This paper provides a synthesis review of the channels the aviation sector interacts with regional economy. The review focuses on quantitative studies that contribute to the state-of-the-art understandings of the causality. We find that the reciprocal causal relationship is more likely to prevail in less developed economies. For more developed economies, only one direction of the causality is recognised, which runs from air transport to economic growth. Especially substantial is the effect of airline enplanement on service-related employment. The reverse direction of the relationship is, however, not as significant as believed in a causal sense within the developed world. Therefore, cautions need to be taken when applying income elasticities (such as the elasticity of air passenger demand with respect to GDP) in air travel demand forecasting, which implicitly assumes that economic growth causally leads to air traffic increment. Based on the fundamental links between air transport and economic growth, some typical imperfections and inefficiencies in aviation markets are discussed and promising avenues for future research are proposed.     

线性需求下铁路客运差别定价模型研究

为提高席位资源利用率,研究了线性需求下我国铁路客运差别定价策略的优化模型。以收益最大化为目标,基于最优化理论和完全价格歧视策略,确定旅客群体最优细分数目以及每个旅客群体的最优票价,得出在客运淡季,铁路旅客最优细分数目为3~5个,各旅客群的最优票价由铁路客运市场细分数目决定。应用该模型为某城际高铁进行差别定价,试验结果表明,该模型可达到调节客流、增加收益的目的。     

A statistical analysis of consumer perceptions towards automated vehicles and their intended adoption

ABSTRACT

While automated vehicle (AV) development continues to progress rapidly, how the public will accept and adopt automated vehicles remains an open question. Using extensive survey data, we apply cluster analysis to better understand consumer perceptions toward potential benefits and concerns related to AVs with regard to factors influencing their AV adoption likelihood. Four market segments are identified – ‘benefits-dominated,’ ‘concerns-dominated,’ ‘uncertain,’ and ‘well-informed.’ A random parameters multinomial logit model is then estimated to identify factors influencing the probability of respondents belonging to one of these four market segments. Among other influences (such as socio-economic and current travel characteristics), it is found that ‘Millennials’ have a higher probability of belonging to the well-informed market segment, ‘Gen-Xers’ with a lower probability to the uncertain market segment, and ‘Baby Boomers’ with a higher probability to the concerns-dominated market (relative to the ‘Great Generation’). We also study the individuals’ expressed likelihood of AV adoption using separate random parameters ordered probit estimations for each of the four market segments. The substantial and statistically significant differences across each AV consumer market segment underscore the potentially large impact that different consumer demographics may have on AV adoption and the need for targeted marketing to achieve better market-penetration outcomes.

IPO择时行为对资本结构的影响分析

基于资本结构的市场时机选择理论,本文以2006-2010年沪深两市IPO公司为研究对象,建立实证分析模型,研究IPO市场时机选择行为对资本结构的影响。实证结果表明沪市不存在明显的IPO择时行为,而深市较为明显,且此行为对资本结构构有长期影响,但其影响力有限,不及传统因素。
