国际油价波动对中国物价水平影响的研究——基于协整和状态空间模型的估计

国际油价波动通过产品供需、产业传递、货币政策等渠道传导至国内经济体系.笔者利用国际油价与国内CPI、PPI月度数据,检验变量的平稳性及协整关系,并以此为基础构建变系数状态空间模型描述变量间的动态关系.结果发现,国际油价波动确实影响国内CPI、PPI变动,价格弹性是可变的,在油价上升期大于下降期;国际油价波动对PPI的影响效应大于对CPI的影响效应.     

国际原油价格波动对我国工业品出厂价格的影响——基于行业层面的实证分析

随着我国石油消费量和进口量的不断增长,国际原油价格的波动对我国经济的影响越来越大。基于38个行业的月度数据,本文详细分析了2003年1月-2009年2月国际原油价格波动对我国PPI指数的影响,研究发现:尽管为了降低国际油价对国内经济的冲击,政府仍对成品油定价体制实行部分调控,但国际原油价格的波动对我国PPI指数仍具有重要影响,尤其是生产资料价格以及石化行业等高耗能行业,而这主要与各行业的能源消费总量和能源利用效率有关。为此,我国应加快国内成品油定价体制改革,实施有效的产业政策,以促使各行业提高其能源利用效率,并最终有效地降低国际油价波动给我国经济带来的价格效应。     

浅谈国际油价波动与我国通货膨胀的关系

石油是最为重要的能源,对经济发展具有决定性的作用.国际油价的波动对我国经济有着十分重要的影响,尤其容易导致通货膨胀的局面出现.本文基于对油价波动与通货膨胀关系的概述,综合探讨了国际油价波动对我国物价水平的影响、传导途径及深层次的相互作用机制,并在最后提出了一系列降低国际油价波动影响的措施.     

国际油价对中国新能源股价的波动溢出效应——基于尾部相依性视角的分析

“双碳”目标下新能源行业的平稳健康发展至关重要,研究国际油价对中国新能源行业股价的波动溢出效应对于我国推进新能源产业健康发展具有重要意义。本文采用QVAR-DY模型实证研究了国际油价对我国新能源股价的波动溢出效应及其尾部特征。实证结果表明,从新能源整体行业来看,国际油价波动对我国新能源股价存在明显的溢出效应且尾部溢出明显强于平均水平,左尾和右尾溢出具有相似的时变特征,均在金融体系脆弱性上升时期显著攀升,但多数情况下,左尾溢出强于右尾;从新能源细分行业来看,同一大类下的细分行业受国际油价波动的溢出影响具有相似性,但不同大类之间存在明显差异,当中美贸易摩擦和产油国超预期减产等极端事件发生时,新能源生产类行业和储能行业受国际油价波动的溢出影响要强于新能源应用类行业。     

浅析2008年油价高位震荡对中国经济的影响

：2008年，国际油价出现了罕见的短期巨幅震荡。本文通过分析此轮石油价格震荡的特点和原因，来阐述国际油价波动对我国经济的影响，并就此提出建议。合理及平稳的油价有助于我国国民经济健康发展，缓解通货膨胀压力。我们应抓住契机，健全中国石油安全保障体系，减轻油价暴涨暴跌对中国经济的负面影响，促进经济发展，维持社会稳定。     

国际油价在向谁叫板

2000年国际油价的剧烈变动并非是由供求关系变化引起。国际油价暴涨对发达国家和国际大资本有利。考虑到后备资源严重不足的现状，中国将可能是国际油价大幅波动的最主要受害国。中国石油进口的增长速度要远比前期估计快得多。我们需要有一支采用金融化操作方式、介入投机性运作、从事风险贸易的强大力量，一方面从市场的价格波动中博取更多国际比较收益，另一方面保证对国内需求的均衡供给。     

如何应对国际油价波动

众所周知，国际油价在1999年和2000年暴跌和暴涨，现仍居高不下。此次油价的剧烈波动，对我国经济影响巨大。     

我国石油价格联动波动率研究

鉴于目前国际国内油价剧烈波动的现状,本文以国际原油价格Wti和中国大庆石油价格作为研究分析的对象,利用算术平均法和ARCH族模型计算出平均历史波动率,通过比较分析发现,两种方法的估计结果基本相符。另外,采用了ARCH族波动率模型进行研究,提出适合我国金融基础资产波动率的预测模型,有益于金融资产的风险管理和定价方面的研究。     

外部冲击、人民币汇率与宏观经济稳定——基于块外生的SVAR模型

该文通过一个九变量块外生SVAR模型,全面讨论了三个主要外部冲击美国利率、美国收入和国际油价对中国经济的影响。研究表明:美国利率和收入冲击对我国经济的影响基本符合传统蒙代尔弗莱明模型的结论;美国货币政策对我国货币政策具有短暂的传染效应,反映了我国货币政策具有较大的独立性;国际油价冲击没有导致我国经济出现传统宏观经济学中讨论的滞胀问题。外部冲击对我国几个主要宏观经济变量均有显著影响。从相对重要性来看,美国利率冲击对我国宏观经济影响最大,分别解释了我国外汇储备波动的11.5%、汇率波动的15%、GDP波动的20%和通货膨胀波动的9%;美国收入和国际油价冲击对我国宏观经济影响相对较小。研究结果表明,2014年以来我国宏观经济增速下降很大一部分原因来自于美国不断紧缩的货币政策。美联储未来的加息政策将对我国宏观经济稳定带来重要挑战。     

油价冲击、货币政策调整与产出波动——基于中国的经验证据

本文基于我国2001-2010年宏观经济月度数据,采用SVAR模型分析了国际油价波动时,央行货币政策在排除回应油价干扰与未排除干扰下的反应差异及油价波动对产出的影响。研究发现,在排除货币政策回应油价波动干扰后,通过脉冲响应函数反映的油价波动对产出的短期负面影响消失。方差分解结果显示,长期内产出波动由油价冲击和货币政策解释的比例分别为5716%和32480%,比排除干扰前分别下降了2569%和4560%。这说明我国油价冲击带来的经济衰退主要是因为货币政策及其回应油价冲击紧缩所致。此外,面对油价的短期冲击,CPI指数并未随着生产者购进价格指数上升而上升,产出也未发生明显的衰减;但在较长时间内,油价上升会因为相对价格的改变,而影响CPI水平和货币政策,从而对产出产生显著的负面影响。     

国内外原油市场收益率及其波动性的双长记忆性测度

本文基于我国原油现货价格和欧洲Brent原油现货价格的数据,运用多种计量模型对原油市场收益率及其波动性的长记忆性进行测度。研究发现,我国原油市场收益率序列不存在长相依性特征,波动率序列则存在长记忆性效应;国外原油市场收益率及波动率序列均存在显著且较强的长记忆性。同时,检验结果表明,采用Student-t分布来刻画"尖峰厚尾"分布性质并利用TGARCH模型来描述"杠杆效应"是非常必要的。     

Oil price and automobile stock return co-movement: A wavelet coherence analysis

This paper explores possible co-movement between oil price and automobile stock return in a joint time-frequency domain. Daily price series from August 01, 1996 to June 20, 2017 is used in this analysis. The results indicate that the co-movement between oil price and automobile stock return is strong during November, 2000–December, 2002 and March, 2006–December, 2009. The co-movement is found to be more pronounced in the long-term and stock return is sensitive to the higher oil price emanating from the demand shock. This contravenes the conventional wisdom that crude oil is always counter-cyclical to the automobile stocks. For investor, this weakens the probable gain from including oil asset in a portfolio of automobile stocks as crude oil does not offer cushion against bearish automobile stock markets during the crisis period.     

我国石油对外贸易存在的问题及发展对策

我国是一个发展中大国,石油是我国工业化进程中所不可或缺的基础能源之一,而我国石油供需不平衡的趋势也是不能避免的.因此,石油对外贸易将成为我国石油石化工业未来发展的一个重大论题.     

Time-frequency dynamics of return spillover from crude oil to agricultural commodities

ABSTRACT

We explore return spillover from crude oil to ethanol, corn, soybean and wheat on daily data during 17 May 2005–27 June 2018. This study is unique in capturing the time-frequency dynamics of return spillover. We use the frequency-dependent spillover measure that jointly captures information from time and frequency domain. We also identify two endogenous break dates that segregate the study period in three sub-periods. Our results indicate that return spillover from crude oil to ethanol, major feed stocks (i.e. corn and soybean) and food crop (i.e. wheat) is pronounced only in lower frequency band or long-term (more than 1 month). We find that return spillover is stronger only during 2005–2010, i.e. the period of energy and food crisis.     

行政垄断、放松规制与产业绩效——基于原油开采业的实证分析

我国原油开采业是行政垄断而不是自然垄断,而行政垄断下原油开采业的市场绩效表明了其危害性.通过对我国原油开采业1998年的隐性放松规制进行界定,建立计量模型对这次放松规制的效果进行了实证分析,从理论和实践两方面证实了放松规制有利于我国原油开采业产业绩效的提升.     

布伦特原油价格与美元指数的交互相关性分析

以北海布伦特原油的现货价格和美元指数为研究对象，探讨它们之间的交互相关关系。首先运用交互相关统计量定性地说明布伦特原油价格和美元指数之间存在交互相关关系。然后利用多重分形分析法对它们之间的交互相关性作定量的分析，证实了它们之间的交互相关性具有多重分形特征。同时运用MF-DFA方法对单个研究对象进行自相关分析。     

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.     

Return and volatility spillovers between china and world oil markets

We examine return and volatility spillovers between China and world oil markets. This topic is of great importance because China is the world's second-largest oil importer and has exhibited substantial growth in oil consumption. Extending Diebold and Yilmaz's (2012) method of catching spillover dynamics, it is found that return and volatility spillovers between China and world oil markets are bi-directional and asymmetric. The Chinese oil market is highly affected by world oil markets and exerts an influence on world oil markets, although to a lesser extent. Moreover, the volatility spillover index has increased significantly since the peak of the last financial crisis in September 2008. Although the US oil market impacts China's market most in terms of spillover, the influence of China's oil market on the world oil market has intensified in recent years.     

A股市场上的“中石油魔咒”现象及其解释

文章针对A股市场上流传甚广的"中石油魔咒"现象,首次从基本面角度进行了解释,认为造成这一现象的根本原因是国际原油价格对我国股票市场存在显著的负向溢出效应,即当国际原油价格上涨时,对中石油个股产生利好,但对整体宏观经济却构成利空,因而中石油股票价格上涨,整个股票市场却会下跌。进一步研究还发现,这种负向溢出效应具有非线性特征,表现为国际原油价格上涨对股票市场的打压力度要大于其下跌对股票市场的提升力度。这提醒A股投资者相对于国际原油价格下跌,要更加关注国际原油价格上涨带来的投资风险。     

Liquidity and crude oil prices: China's influence over 1996–2011

Movement in China's money supply is shown to drive the movement in world money supply over the last fifteen years. Structural shocks to G3 (U.S., Eurozone and Japan) real M2 and to China's real M2 are both large over 1996:1–2011:12. The cumulative impact of real G3 M2 shocks on real oil prices is small and statistically insignificant. In contrast, the cumulative impact of China's real M2 on the real price of crude oil is large and statistically significant. Following a sharp fall in real oil price in the last half of 2008, the cumulative impact of China's real M2 on the real price of crude oil is particularly substantial in the recovery of oil price during 2009 from a low of $41.68 for January 2009. The analysis sheds light on the causes of movement in oil prices over the last fifteen years and in assessing the relative importance of China in the upsurge of the real price of crude oil.
