中国制造业企业500强总部空间格局及区位选择

运用Arc GIS9．2软件并基于点和面两个方面对2004-2008年的中国制造业企业500强总部空间格局特征进行测度,具体结合核密度指数、Moran’s I、Getis—Ord GeneralG和Ceils—Ord Gi^＊等指标,结果表明：基于点层面,企业总部主要分布在长三角、环渤海以及珠三角等区域,尤以前两者更显著;基于面的层面,全局空间集聚程度较低,其中热点区布局较稳定,并以长三角和环渤海为主,而珠三角有日益衰退趋势,而其增长格局呈现出极强的随机性和不稳定性;2004-2005、2005-2006和2006-2007年时段增长热点区与冷点区均集中在长三角、环渤海和珠三角。2007--2008年热点区范围与数量远高于前3个时段,而全国大部分区域已由次冷区转为次热区。以此为基础,本文结合城市的服务业水平、基础设施建设、可达性、人力资源以及拥有权力等方面的11个影响因素,并采用Eviews3．1软件对其进行定量测度和分析。     

UCP600的诞生及与UCP500比较分析

国际商会于2006年10月25日通过新版《跟单信用证统一惯例》即UCP600(2007年版本),UCP600将于2007年7月1日正式取代现行十多年的UCP500在国际范围全面实施。认识新的《跟单信用证统一惯例》对于从事外贸跟单业务的工作人员有非常重要的意义,文章简要概述了UCP600的诞生过程及UCP600与UCP500的主要区别,旨在让人们对UCP600有一个整体把握。     

The implied volatility smirk of commodity options

This paper studies the implied volatility (IV) smirks in four commodity markets by adopting Zhang and Xiang's methodology. First, we document the term structure and dynamics of IV smirks. Overall, the commodity IV curves are negatively skewed with a positive curvature. Then we analyze the commodity and S&P 500 returns' predictability based on in‐sample and out‐of‐sample tests and find that the information embedded in IV smirks can significantly predict monthly commodity and S&P 500 returns. For example, the risk‐neutral fourth cumulant (FC) from the crude oil market outperforms all of the standard predictors in predicting the S&P 500 returns.     

新惯例(UCP600)给跟单信用证业务带来的新变化

2007年7月1日,国际商会制定的信用证新规则——UCP600正式实施,UCP600与原有UCP500相比有许多不同。本文介绍了UCP600的产生背景及过程,分析了UCP600给信用证业务带来的新变化。     

广西500kV线路铁塔覆冰倒塌原因浅析及建议

2008年初桂北等地区发生罕见的雨雪自然灾害,导致大量输电线路导线断裂,铁塔折损。文章针对柳桂500kV线路直线与转角塔横担折断情况进行初步原因分析,并针对设计条件提出了新的见解,为以后线路工程的开展提供了理论依据。     

UCP600对UCP500的重大变动分析

UCP600是跟单信用证的第六次修订,取代UCPS00为跟单信用证业务的实务操作提供了新的标准。但UCPS00在进出口商中已根深蒂国,本文从UCP600与UCPS00的比较出发,依据跟单信用证的业务环节,对UCP600在结构和内容上所作的实质性变动进行了梳理,以使进出口商能够在国际贸易中准确理解和运用新的惯例来拓展业务,规避风险。     

EXPLAINING THE GROWTH OF GOVERNMENT SPENDING IN SOUTH AFRICA

What determines government spending in South Africa? The paper estimates the determinants of real per capita government spending in the Republic of South Africa using annual data for the period 1960‐2007, a tumultuous period during which South Africa experienced a variety of internally imposed changes (e.g. the abolition of apartheid, changes in political institutions) and externally generated shocks (e.g. war, oil shocks). Using multivariate cointegration techniques, we find that per capita government spending, per capita income, the tax share and the wage rate are cointegrated, a result that supports the notion that government spending is associated not only with per capita income and the true cost of government service provision as given by the wage rate but also with the fiscal illusion caused by budget deficits. We also find evidence that per capita government spending was positively affected by external shocks. These external shocks seem to play a significant role in explaining the dynamics of government spending growth.     

PROPOSALS FOR STRENGTHENING THE SARB'S INFLATION TARGETING REGIME

This paper proposes a set of criteria for efficient institutions derived form the New Institutional Economics literature and the IMF's Code of Good Practices on Transparency in Monetary and Financial Policie. These criteria are used to evaluate the institutional framework of South Africa's inflation targeting regime. A test for measuring the comprehensiveness of South Africa's inflation targeting regime is used to verify the results of the institutional evaluation. Finally, a matrix of proposed institutional reforms is constructed to address weaknesses identified by the institutional evaluation.
