对我国区际经济与金融差距关联性的实证分析

各区域间金融发展的差异对经济发展差距有无影响以及影响机制如何成为经济学研究的一项任务。以塞尔指标衡量我国经济与金融发展差距,发现我国区域间经济发展差距与金融发展差距呈现一致的变动关系,且金融差距大于经济差距。由此引出的基本判断是我国区际经济差距的逻辑原因有金融因素,进而采用格兰杰因果关系检验判断我国省际金融发展与经济增长间的关系,从中可以明确我国东部地区金融成长偏重于内生状态,而中西部地区更倾向于外生状态。考虑到改革的总体方向,并借鉴东部地区的经验,放松金融抑制、催化内生金融成长无疑是全面促进中西部经济发展的必然选择。     

汇率波动率与中国对主要贸易伙伴的出口

本文研究汇率波动率对中国向三个主要贸易伙伴美国、欧盟和日本出口的影响。通过协整检验,误差修正模型和Granger非因果检验等方法估计变量间长短期的关系。研究表明,中国向美国和欧盟的实际出口与实际汇率波动率存在长期显著的负相关关系,而中国向日本的出口与汇率波动率无关。短期内汇率波动率只影响中国向美国的出口,对向欧盟和日本的出口没有影响。     

A multivariate time series analysis of energy consumption,real output and pollutant emissions in a developing economy: New evidence from Nepal

Mountain economies will have to play a central role in attaining the global pursuit of green economic growth as crucial bearers of ecosystems goods and services. However, these economies are not adequately represented in the development policy debates in spite of their fundamental importance towards global sustainable development. This study examines the inter relationships between energy consumption, output and carbon emissions in a developing mountainous economy using an augmented Vector Autoregression model. Time-series data over the period 1975–2013 is studied applying a multivariate framework using population and gross fixed capital formation as additional variables for Nepal. Testing for Granger causality between integrated variables based on asymptotic theory reveals a long-run unidirectional Granger causality running from GDP to energy consumption, and a unidirectional Granger causality running from carbon emissions to GDP. We suggest that the government of Nepal can address energy poverty by accelerating the adoption energy conservation policies such as rationing energy consumption and energy efficiency improvements to narrow the energy supply-demand gap. The opportunity to promote the uptake of decentralised off-grid renewable technologies in remote areas and the large scale development of hydropower at the national level also needs to be prioritized. Our results remain robust across different estimators and contributes to an emerging literature on the nexus relationships between energy consumption, income and carbon emissions in mountainous developing economies.     

Are imports and remittances cointegrated for the Central and Eastern European countries?

In this article, we investigate the existence of long-run common trends between imports and remittances in 11 Central and Eastern European countries which are part of the European Union. Using the Engle–Granger two-step procedure, we determine that for all countries in our sample there are no long-run common trends (no cointegration) between imports and remittances. However, the results are mixed when running a Granger causality test. For nine countries, we can establish either a bidirectional or unidirectional Granger causality, indicating that past values of one variable have predictive content on the other variable. In two countries, there is no Granger causality between imports and remittances.

中国内地与香港贸易关系的实证分析

长期以来,香港是中国重要的贸易顺差来源地和重要的转口贸易地,同时,香港对外贸易的发展也离不开内地的支持.两地贸易的相互依存度正在不断上升.香港进口与出口之间具有互动的因果关系.香港的进口带动出口的发展,香港出口的增加,促进了产品价值的实现,可以进口更多更好的产品或投入品,形成良性循环.中国内地进出口的发展处于不平衡状态,特别在改革开放初期,重视出口、忽视进口的现象比较严重,进出口互动发展格局尚未形成.因此,不断调整中国内地进出口产品数量、优化贸易结构,对于中国内地对外贸易的发展具有重要意义.     

基础设施投资与吸引外国直接投资关系的实证研究——基于我国经济转型期二者因果关系的检验

本文在现有国内外研究的基础上,依据我国改革开放20多年来的实际数据,针对基础设施投资与外国直接投资(FDI)之间的相关性进行了协整检验和格兰杰检验,结果发现:二者之间不仅存在协整关系,还存在单向的格兰杰因果关系,即FDI是带动基础设施投资的格兰杰原因,而基础设施投资并不是引致FDI增加的格兰杰原因。本实证检验还用事实证实了目前许多地方政府以增加基础设施投资来吸引外商投资的盲目性。     

Cointegration and causality in the Asian and emerging foreign exchange markets: Evidence from the 1990s financial crises

This article examines the cointegration level, changes in the existence and directions of causality of the foreign exchange (FX) rates in the Asian and emerging markets during the 1990s financial crises. Engle and Granger's simple bivariate and Johansen's multivariate cointegrations are applied to the FX rates for the 1994 Mexican, 1997 Asian, 1998 Russian, and 1999 Brazilian crises. In addition, the article conducts the Granger causality test and impulse response analysis to examine the causality pattern in all the FX rates. The analysis shows most of the pre-Mexican causality disappears and significant numbers of new causality emerge in the 1994 Mexican crisis while the 1997 Asian crisis generates significant spillover effects into the later part of the 1998 Russian and 1999 Brazilian crises.     

FDI、对外贸易与经济增长的协整性研究——以山东省为例

关于利用外资、进出口贸易与经济增长关系的研究一直以来备受关注,但近年来的研究大多致力于两者间关系的独立性研究,其结果往往会使得理论与实证研究的解释力受到影响。对于多个同阶序列变量之间是否存在长期稳定的均衡关系的研究,协整理论具有重要的应用,其既可充分利用信息资源,还有效避免了“伪回归”问题。另外鉴于不同区域问经济发展模式、发展水平的差异性,各经济要素之间的关系也不尽相同,本文采用山东省1984～2007年间24年的统计数据,对该省的外商直接投资、进出口贸易与经济增长之间的相互关系进行了协整性检验和误差修正模型分析,总结得到有关结论：山东省利用外资、进出口贸易与其经济增长之间存在长期均衡关系,但具有区别于其他地区的自身特点。最后,针对山东经济的协调发展提出了若干政策建议。
