通过构建服务贸易出口决定模型,利用1982~2010年数据研究中国FDI、第三产业发展和服务贸易出口的关系.研究发现上述变量存在长期均衡的协整关系.在误差修正模型基础上对上述变量间的Granger因果关系检验结果表明,变量间的长期效应与短期效应有所不同,有的变量间的作用方向发生了逆转,其中的原因值得探究.  相似文献

在测算我国高技术产品对外贸易对经济增长的贡献度和拉动度的基础上,运用计量经济学模型检验了高技术产品进出口贸易的经济增长效应。结果显示:中国高技术产品进出口、非高技术产品进出口与经济增长之间存在长期稳定的均衡关系,高技术产品的出口、非高技术产品进出口对经济增长有显著的促进作用,而高技术产品进口对经济增长的贡献尚未发挥出来。从高技术产品的进出口主体看,内资企业的出口对经济增长的促进作用十分显著,而外资企业的出口对经济增长促进作用并不明显,外资企业和内资企业高技术产品的进口与经济增长均呈负相关关系。为了进一步增强高技术产品的进出口贸易对经济增长的贡献,中国应着眼于培育战略性新兴产业高技术产业群,着力促进一般贸易方式下高技术产品的出口,并鼓励外商投资企业在华投资和在华开展技术研发活动。  相似文献

以商标作为创新度量指标,使用1997~2008年我国24个地区的数据,运用面板Granger方法对风险投资与创新进行因果检验。实证结果表明,风险投资与注册商标都是一阶单整变量;Pedroni检验、Johansen Fisher检验和Kao检验均显著,说明风险投资和创新变量间存在长期稳定的均衡关系。基于误差修正模型的Granger因果检验结果表明,不论是在短期还是长期,均存在人均注册商标到风险投资的单向因果关系,验证了创新先于风险投资的假说;但没有发现风险投资先于创新在短期和长期内的明显证据。  相似文献

随着经济体制改革深入推进,我国财政收入超经济增长现象愈加明显.为合理解释资产价格变化与财政收入增收之间的关系,本文构建了一个由财政收入增长率、货币市场利率、证券市场收益率和房地产市场收益率等4个变量组成的封闭系统,并从研究各变量间相互关系人手,分别建立各变量间的长期协整关系与短期关系模型,以期找出资产价格变化与财政收入增减变动间的内在关系.  相似文献

本文考察了我国区域金融发展水平与高技术产业出口贸易比较优势的关系。国内外相关研究表明,金融发展通过减少企业融资成本,进而影响行业贸易的比较优势。本文选择区域高技术产业出口值作为研究对象,通过测算出区域非国有企业贷款比重衡量区域金融发展水平,同时加入其他控制变量,运用省际面板模型反映金融发展对高技术产业贸易的影响。结果表明,区域金融发展对高技术产业出口贸易具有显著影响。  相似文献

汇率作为影响出口的关键变量,其变动将对出口产业产值及就业产生重要影响.本文基于汇率对就业的影响路径,从贸易部门和非贸易部门对人民币实际有效汇率与就业的关系进行实证研究,结果表明,我国贸易部门和非贸易部门的就业与实际有效汇率不论长期还是短期,均存在着协整关系;实际有效汇率的升值会使我国就业减少,反之亦反;并且,实际有效汇率对贸易部门就业的影响程度高于非贸易部门.  相似文献

文章从高技术产品占对外贸易的比重、贸易竞争力指数、贸易方式、出口的企业类型分布以及高技术产业增加值的企业类型分布等角度,分析了我国高技术产品的出口情况.认为我国高技术产品出口及其占世界份额的迅猛增长,实质是建立在外资绝对控制的、对国外高技术产品进口高度依赖的、加工贸易占主导地位基础之上的.我国高技术产品出口繁荣表象的背后,是我国企业自主创新能力的不足和对发达国家严重的技术依赖.我国企业的自主创新能力亟待提升.  相似文献

2005年以来伴随着人民币对美元的持续升值,人民币汇率的波动对我国贸易影响逐步加深。人民币汇率与我国贸易结构的关系也成为人们探讨的一个热点问题。本文基于汇率弹性分析了汇率影响进口商品结构的机制,通过建立中国资本密集型、劳动密集型产品进口额与人民币名义有效汇率等变量的协整模型,分布滞后模型,以及脉冲响应函数系统分析了人民币汇率的波动对我国进口商品结构在短期和长期的影响。并提出应充分利用汇率改革的契机,加快我国贸易结构优化升级的步伐。  相似文献

This paper examines systematic differences in the level of accounting conservatism between high-tech and low-tech firms. Relying on the recent development in theoretical models and empirical measures of conservatism, we investigate conservative accounting practices and earnings management behavior in high-tech and low-tech firms. The results based on comparisons of cumulative nonoperating accruals, regression coefficients from the income timeliness models in Basu (1997), the distribution of earnings, and discretionary accruals between the two groups are consistent with a higher level of accounting conservatism in high-tech firms vis-à-vis low-tech firms. Additional analyses show that the effect of conservatism cannot be used as a defense for the over-valuation of high-tech firms.  相似文献

基于1999年一季度至2008年三季度的中日两国数据,本文运用协整检验方法分析了影响两国外汇储备规模的宏观经济因素和变量间的长期均衡关系及短期波动关系。研究表明:(1)从长期来看,对外贸易规模、名义有效汇率、经济总量三个宏观经济变量都影响着中日两国外汇储备的长期均衡规模,且两国外汇管理制度的巨大不同解释了协整系数的差异。(2)从短期来看,协整方程对两国外汇储备短期波动的调整作用均较为显著,而对于中国而言,宏观经济变量的滞后影响的作用时间更长。  相似文献

In 2011, Colombia instituted a tax on repayment of bank loans, which increased the cost of short‐term bank credit more than long‐term credit. Firms responded by cutting short‐term loans for liquidity management purposes and increasing the use of cash and trade credit. In industries in which trade credit is more accessible (based on U.S. Compustat firms), we find substitution into accounts payable and little effect on cash and investment. Where trade credit is less available, firms increase cash and cut investment. Thus, trade credit provides an alternative source of liquidity that can insulate some firms from bank liquidity shocks.  相似文献

We investigate the short‐term relation between individual investor trading and stock returns on the Australian Securities Exchange. Stocks heavily bought by individual investors underperform stocks heavily sold over the subsequent three days, with respective returns on to a long–short portfolio of ?93, ?67 and ?12 basis points on days one, two and three. Individuals underperform in small and mid‐size stocks when they trade passively using limit orders waiting for the market price to move in their favour. Individuals underperform in large stocks when they trade aggressively using marketable orders. Foreign institutions gain from taking the opposite side of individual trades. We present an information asymmetry‐based explanation for the findings.  相似文献

出口信用保险对我国出口贸易影响的实证分析   总被引:3,自引:0,他引:3  
王智慧 《海南金融》2010,(10):56-61
出口作为拉动经济发展的"三驾马车"之一,在我国经济发展中起到举足轻重的作用,为了促进出口贸易的发展,我国实施了多项出口贸易鼓励政策。本文对出口退税、出口信用保险、出口贸易三个变量进行协整分析,并通过VAR模型估计以及脉冲响应函数及方差分解的实证分析,得出三个变量的相互关系;同时通过两个因素的实证比较,得出出口信用保险虽然在短期内对出口贸易的影响还不够显著,但从长期看却是显著的,并且要大于出口退税对出口贸易的影响程度,最后提出发展我国出口信用保险的政策建议。  相似文献

We examine the relationship between performance measurement systems and short‐termism. Hypotheses are tested on a sample of senior managers drawn from a major telecommunications company to determine the extent to which the diagnostic and interactive uses of financial and non‐financial measures give rise to short‐termism. We find no evidence to suggest that the use of financial measures, either diagnostically or interactively, leads to short‐term behaviour. In contrast, we find a significant association between the use of non‐financial measures and short‐termism. Results suggest that the diagnostic use of non‐financial measures leads managers to make inter‐temporal trade‐off choices that prioritise the short term to the detriment of the long term, while we find interactive use is negatively associated with short‐termism. We find an imbalance in favour of the diagnostic use over the interactive use of non‐financial performance measures is associated with short‐termism. Overall, findings highlight the importance of considering the specific use of performance measures in determining the causes of short‐termism.  相似文献

Recent studies show that single‐quarter institutional herding positively predicts short‐term returns. Motivated by the theoretical herding literature, which emphasizes endogenous persistence in decisions over time, we estimate the effect of multiquarter institutional buying and selling on stock returns. Using both regression and portfolio tests, we find that persistent institutional trading negatively predicts long‐term returns: persistently sold stocks outperform persistently bought stocks at long horizons. The negative association between returns and institutional trade persistence is not subsumed by past returns or other stock characteristics, is concentrated among smaller stocks, and is stronger for stocks with higher institutional ownership.  相似文献

文章考察了中国资本流动现状,并从资产组合理论的视角对未来中国资本流动形势进行了分析,认为中国资本外流压力短期内不可小觑,长期内不必夸大,我国资本流动方向不会根本逆转。短期内,中国应尽量减轻或消除人民币贬值预期,努力稳定外贸形势,落实各项稳增长措施,保持宏观经济基本稳定;长期内,中国应继续深化改革开放,进一步完善市场经济体制,转变政府职能,改善经济发展环境,遏制收入分配扩大趋势,保持各方对中国经济和社会稳定发展的信心。  相似文献

Abstract:   This paper investigates the initial pricing and performance of Canadian unit trust IPOs over a three‐ to four‐year period and then draws implications for the efficiency of the Canadian market. Overall, the results confirm the following: in the short term, unit trust IPOs are underpriced and outperform the Canadian market; in the medium term, IPOs are fairly priced and neither outperform nor underperform the Canadian market; and in the long term, IPOs are fairly priced but underperform the Canadian market. In addition, our results confirm that the size of underpricing is related to ex‐ante uncertainty about the value of the issue. Ex‐ante uncertainty proxies, namely total risk, exchange listing, relative bid‐ask spread, and relative volume of initial trade, all explain the size of underpricing. When the effects of these factors are controlled, the results confirm that Canadian unit trust IPOs are indeed overpriced in the short term but underpriced in the long term. We conclude that the Canadian unit trust IPO market appears to be inefficient in the short and long term, but over the medium, the market appears to be efficient.  相似文献

金融危机对世界农业的影响最终体现在农产品价格变化上。从短期来看,表现为国际大宗农产品价格高位回落。从长期来看,金融危机将对农产品的需求、供给和贸易产生进一步影响,而且有可能导致新一轮的农产品供需矛盾出现,世界农产品价格可能再次大幅上升。因此,我国要千方百计保证主要农产品有效供应,以减小金融危机对我国农业的影响。  相似文献
