R&D经费支出结构与科技创新人才培养的协整检验——基于1995—2008年的数据分析

为探索我国R&D经费支出结构与科技创新人才培养之间的关系,运用协整方法对样本期内的数据(1995-2008年)进行协整检验。首先对R&D经费支出结构和科技创新人才培养结构变动进行分析,然后对样本进行单位根检验、协整检验和Granger因果关系检验,实证结果表明:R&D经费支出结构与科技创新人才培养结构之间存在长期均衡关系。     

基于协整理论的中国宏观消费函数分析

本文采用 1978———2002年间的宏观消费与收入数据,运用协整理论,对中国宏观消费函数的实证分析。分别对数据进行了单整和协整检验,在检验的基础上建立了中国宏观消费与收入的误差修正模型和长期均衡关系。分析结果表明:全样本时间段内,消费与收入均为三阶单整序列,但不存在协整关系;以 1991年为界将全部样本分为两段后检验发现,该两个时间段内的消费与收入均存在协整关系。从而,中国宏观消费与收入的误差修正模型和长期均衡关系都存在。     

人口流动与旅游收入关系的实证研究

通过对中国1985-2004年人口流动与旅游收入的有关数据变量进行协整分析与因果关系检验,并建立了二者之间的误差修正模型,揭示了人口流动与旅游收入的动态均衡关系.协整检验结果表明,自20世纪80年代中期以来,我国旅游收入与人口流动之间存在着长期稳定的均衡关系.通过格兰杰检验结果表明人口流动的增加是旅游收入增长的格兰杰原因.     

长株潭城市群高等教育资源分布与区域经济增长的实证研究：1989-2009

利用长株潭1989-2009年数据,对长株潭高等教育资源与区域经济增长之间的关系进行分析研究,经过了平稳性检验、协整检验及格兰杰因果关系检验和建立了误差修正模型,可以发现两者之间存在长期稳定的均衡关系。实证结果表明,长株潭高等教育资源分布与区域经济增长之间存在着长期均衡即协整关系;长株潭高等教育资源分布的多少与区域经济增长之间互为格兰杰因果关系;从短期来看,长株潭高等教育资源的发展规模对该区域经济变动的影响不大。针对出现的问题提出相关对策建议。

Sustainability of current account deficits in India: an intertemporal perspective

This study examines the sustainability of current account deficits (CADs) and the validity of intertemporal budget constraint (IBC) in India. The long-run model is estimated on annual data for the period 1950–1951 to 2009–2010. The optimal single-equation and maximum-likelihood (ML) system estimates of the model provide a consistent support for the long-run relationship between imports and exports. The OLSGH estimates provide no support and that ML system estimates a consistent support for cointegration in both the models estimated with one and two structural breaks in level. The new cointegration breakdown tests generally suggest that the cointegration prevails from 1951 to 2010. The evidence supporting the cointegration between imports and exports overwhelms the evidence providing a mixed or no support for cointegration. The estimates of slope parameter above zero and the dominant support for cointegration between imports and exports vindicate the validity of IBC and the sustainability of CADs. The short-term management strategies need to be accompanied by long-term improvements in productivity to reduce inflation, lever up the competitiveness of exports and ensure the sustainability of the external value of domestic currency.     

Economic growth drag in the Central China: evidence from a panel analysis

This article employs recently developed panel methods to test for unit roots, cointegration and Granger causality to justify and estimate the drag induced by resource constraint and environmental pollution for the Central China. The results of the panel cointegration test show that there is a stable long run relationship amongst total output, capital, labour, land, water and SO₂ when total output is the dependent variable. The results of the causality test with Error Correction Model (ECM) analysis suggest that the available water resource and environmental pollutant have no impacts on total output temporarily, but in the long‐run there is a Granger causality running from these variables to total output, indicating the economic growth drag induced by the natural resource and environmental pollution can be further estimated. Given the stable cointegration and significant Granger causality being, the study shows that the drag on the total output reduces annual economic growth rate by about 1.1 percentage points for the Central China as a whole and there is a significant difference on the aggregated and disaggregated drags for the six provinces, which indicates that natural resource and environmental constraints so far incorporated into production probably have a modest effect over the past 31 years for the Central China.     

An investigation into the dynamic relationship between international and China’s crude oil prices

This article studies the dynamic relationship between international (WTI, Brent and Dubai) and domestic (Da Qing) crude oil prices in China using threshold cointegration method. We find evidence of a long-run equilibrium relationship between each pair of international and Da Qing oil prices, favouring the market integration hypothesis. We also estimate asymmetric adjustments under the momentum threshold autoregressive (M-TAR) specification in a TVECM, and the results show that adjustments to eliminate disequilibrium happen faster when oil price spread increases than when it decreases. The long-run and short-run Granger causality tests support the notion that China has influence on the international oil markets. The results imply that China should open up its domestic and imported oil markets, and also establish a well-functioning crude oil futures market, as they are essential for arbitrage and hedging strategies.     

产能利用与固定资产投资关系的面板数据协整研究——基于制造业28个行业样本

本文采用1997～2006年我国工业制造业28个行业的有关数据,在使用成本函数法测度产能利用率的基础上,应用面板数据的协整理论对产能利用水平和固定资产投资之间的关系进行了实证分析。实证研究的结果表明,产能利用水平和固定资产投资二者之间存在着协整关系,但产能利用对固定资产投资的影响强度对于各行业来说存在着显著差异性。同时,部分行业产能利用水平与固定资产投资之间呈现正相关性的结果也说明,由于厂商对未来需求波动的预期和现实总存在着一定的偏差,致使产能利用的调整滞后于需求的变化,进而导致投资"潮涌现象"的发生。     

The integration of direct real estate and stock markets in Asia

Currently, there exists relatively little research investigating the long-term association between stock and direct real estate markets. Using appropriate transaction-based property indices, this study focuses on the relationship between stock and direct real estate markets in nine Asian countries from the period 1980 to 2012 through both linear and nonlinear cointegration techniques. We find empirical evidence of linear cointegration of stock and property markets in Taiwan, fractional cointegration in Singapore and Hong Kong and no evidence of cointegration in China, Japan, Thailand, Malaysia, Indonesia and South Korea. It is concluded that segmentation of property markets from stock markets does not appear to be linked to the differences in the maturity of national financial markets and that the differing degrees of integration across Asia may instead be reflective of a range of factors impacting upon the underlying economic structures in each country.     

Causality tests of budget and current account deficits: Cross-country comparisons

This study attempts to determine the causal relationship between budget and current account deficits as well as the direction of such causality. A selected sample of some developed and developing countries with annual time series data is used and cointegration techniques are applied to bring evidence regarding this important issue. Our results do not support any long-run relationship between the two deficits for developed countries while the data for developing countries do not reject such a relationship. However, our results suggest a causal relationship between the two deficits for most of the sample countries. First version received: November 1996/final version received: September 1998     

Threshold cointegration and nonlinear adjustment between goods and services inflation in the United States

In this paper, we model the long-run relationship between goods and services inflation for the United States over the period 1968:1–2003:3. Our empirical methodology makes use of recent developments on threshold cointegration that consider the possibility of a nonlinear relationship between the two inflation series. According to our results, the null hypothesis of linear cointegration would be rejected in favor of a two-regime threshold cointegration model. Consequently, we could expect a cointegrating relationship only when the divergence between services inflation and goods inflation is above the threshold point estimate.     

Unemployment and labour force participation in Turkey

This article investigates the relationship between labour force participation rate and unemployment rate in Turkey a developing country. Cointegration analysis is carried out for the aggregate and gender-specific series. The findings indicate that there is no long-run relationship between labour force participation and unemployment rates in Turkey. Thus, unlike in the case of the developed countries, the unemployment invariance hypothesis is supported in Turkey.     

国际油价波动对经济增长的影响——基于中国的实证分析

基于1990年1月至2009年3月的月度数据,本文实证分析了我国经济增长与国际石油价格之间的长期变动关系,其特点在于,采用稳健性较强的T-Y因果检验来分析油价与经济增长的Granger因果关系,同时,运用非对称协整技术以考察油价与经济增长之间的非线性关系。研究发现：①长期中油价是我国经济增长的单向Granger原因;②油价与我国经济增长之间存在非对称协整关系,油价上涨对经济活动的负面影响大于油价下跌的积极影响。基于中国经济运行的实际,本文还分析了实证结果背后的原因,并提出当前国际金融危机背景下,油价呈下跌趋势,需抓住有利时机,动用外汇储备,大力购入石油资源,建立起石油战略储备;在经济复苏、油价上涨时,可以启动石油战略储备来减少石油供应冲击,从而有助于及时保证我国经济平稳快速增长的政策建议。
