2008全球金融市场状况及预期

金融创新在全球经济一体化的背景下把全球金融联系在了一起是美国金融危机升级为全球金融危机的重要原因,这次金融危机给各国经济和金融市场造成了巨大损失,其负面影响在短时间内不会消除,并会不断向实体经济蔓延.由于当今全球经济一体化,中国不会成为金融危机中的安全岛,一系列的经济发展问题将会受到影响.     

产品内分工视角下中美贸易失衡中的贸易利益研究

中美双边贸易中中方的巨额贸易顺差是否使中方获得了同样的贸易利益,一直是中美两国争论的焦点问题之一。本文在产品内分工框架内,构建了双边贸易利益分配的理论模型,使用面板协整对1997-2009年中美双边8个主要制造业部门的贸易利得进行实证分析。结果表明,美国依靠比较优势和垄断优势占据了产品价值链两端高附加值环节,而中国承担低附加值的中间环节;中美贸易失衡背后的利益流向并没有与贸易差额一致,中国在中美产品内贸易中获利微薄。因此,我国应该努力提升产业结构,提高自主创新能力,力求锁定在附加值高的环节,以赢得更多的国际贸易利益。     

经济高速发展时期河南省土地利用变化分析研究

以河南省为研究区,对不同年份的土地利用数据进行分类系统整合,在此基础上,对河南省1996~2009年土地利用类型进行了对比分析,分析得出耕地、城镇村及工矿用地、林地、交通运输用地面积在增加,园地、草地、水域及水利设施用地、其它土地面积在减少,在各类土地类型转换中,林地是变化最为激烈的土地利用类型,其次是其它土地,变化最稳定的地类是交通运输用地,其次是耕地。     

京津冀区域空间格局及其优化整合分析

本文以京津冀区域空间结构为研究对象,从点、线、网络和域面四个基本空间要素入手,研究提升区域竞争力的空间整合规律.研究认为,京津冀区域人口和城镇体系的空间分布不均衡,一方面,以自然条件为基础,呈现东南集中特征,另一方面,中小城镇分布以京广、京九、京哈铁路等为依托,呈现以北京为中心的强向心分布;城镇带分布大体可划分为京广线...

Global supply network embeddedness and power: An analysis of international joint venture formations

As a subset of the international business literature, cross-border equity based partnerships have drawn significant academic attention. In the context of inter-firm partnerships, the power dynamics between parties and the implications that power has on the relational dynamics between firms is an important consideration. Research that connects power with network theory has recently emerged, suggesting that the network, as a source of power, plays a significant role in inter-firm dynamics. Yet, while there has been a substantial body of work either articulating the antecedents and consequences of power, little research has paid attention to the role that power plays in international JV formations; this presents a significant gap in the international business literature. Consequently, this study investigates the role that global network structure plays in the formation of new equity based international partnerships. Secondly, it contributes to the international JV literature by developing and testing a theoretical framework that examines inter-firm power dynamics as derived from the network position of each firm in the global network. Global network prominence, brokerage and weakness are key factors utilized in the analysis. The hypotheses are tested using a global manufacturing joint venture longitudinal dataset that contains 985,689 observations from 1985 to 2003. The results of the event history analysis indicate that for the manufacturer global network prominence, brokerage and weakness play an important role in new joint venture formations. On the other hand, only global network prominence is a significant factor for the potential partner.     

The nutrition transition and agricultural transformation: a Preston curve approach

The nutrition transition in diets and health is closely tied to other aspects of economic development, including agricultural transformation and urbanization as well as demographic change and epidemiological transition from infectious to noncommunicable disease. Over time, dietary patterns typically shift from widespread inadequacy of many foods and nutrients, especially for children and mothers, into surplus energy intake and rising obesity with continued inadequacy of healthier foods. Diet‐related diseases remain the largest single cause of premature death and disability in all regions. This article combines food availability and dietary intake data from more than 100 countries over 30 years with a wide range of other evidence to characterize the nutrition transition and its association with changes in agricultural production and the food environment, asking how future dietary patterns might be steered toward healthier outcomes as national incomes grow.     

From passenger growth to aircraft movements

Airlines are able to deal with passenger growth by either increasing the frequency or the aircraft size, which may entail different numbers of aircraft movements. Forecasting the latter is necessary for evaluating technologies, approaching future emissions or anticipating capacity constraints. Purpose of this paper is to forecast a typical fleet mix and the growth of aircraft movements on flight segments worldwide based on an assumed passenger growth. The methodology is implemented in a model called Forecast of Aircraft Movements. Basic approach is the assignment of each flight segment worldwide to a distance, passenger number and aircraft category. For each combination of distance and passenger numbers a typical fleet mix is defined. The forecasted worldwide growth of passenger demand and the empirically determined fleet mix is applied to all segments in order to derive a future scenario. Assuming a certain seat load factor, the frequency growth can be deduced from the aircraft movements generated for all segments. The paper includes a forecast for aircraft movements in a future scenario based on real schedule and passenger data and gives a detailed overview of the methodology and results considering airlines' behaviour.
