吉非替尼与厄洛替尼治疗非小细胞肺癌效果的间接比较

目的系统评价吉非替尼与厄洛替尼治疗非小细胞肺癌的临床效果.方法检索国内外公开发表的关于吉非替尼或厄洛替尼治疗非小细胞肺癌的中英文文献,采用Bucher法对纳入的研究进行间接比较.结果共纳入4项吉非替尼vs标准治疗和3项厄洛替尼vs标准治疗的文献进行间接比较.吉非替尼与厄洛替尼治疗非小细胞肺癌的反应率和疾病控制率的 RR 值分别为0.56（P=0.0536）、0.87（P=0.6745）,中位生存期和中位无发展生存期的 MD 值分别为-0.31（P=0.7718）、-3.93（P=0.1443）.结论尽管间接比较存在一定的局限性,但结果表明吉非替尼与厄洛替尼治疗非小细胞肺癌的效果无显著性差异.     

进出口间接作用及其介体与路径——基于三时期参数变结构协整方法的研究

本文运用三时期参数变结构协整方法,着重研究我国进出口对经济增长的间接作用,以及产生间接作用的介体与路径。协整结果发现,大多数考察变量与进出口之间存在显著的参数变结构现象。实证研究得出,进出口通过投资、人力资本、技术进步、消费与经济结构这些介体对经济增长的间接作用有正有负,而加总效应都是正值,出口间接作用的弹性测算值较大,而进口间接作用的弹性测算值较小。     

Connectivity analysis of transshipments at a cargo hub airport

The paper investigates the interconnectivity of airfreight networks as temporal concentrations at airport. The connectivity of freight transshipments depends on both the quality of connections at hub airports and the quality of indirect flights compared to direct flights. Here connectivity of flight schedules is analyzed using a temporal wave structure to estimate the degrees of connectivity and the quality of connectivity.     

欧盟间接税协调对泛北部湾次区域合作的启示

作为中国—东盟自由贸易区框架下＂海上次区域＂经济合作的新平台,泛北部湾次区域已逐渐成为中国—东盟自由贸易区的前沿地带。加强该区域内各国的间接税协调,将对整个自由贸易区的经济一体化发展产生重要影响。本文旨在借鉴欧盟间接税协调的实践经验,对泛北部湾次区域合作的间接税协调进行探讨。     

DEVELOPMENT OF REGIONAL SOCIAL ACCOUNTING MATRICES WITH DETAILED AGRICULTURAL LAND RENT DATA AND IMPROVED VALUE-ADDED COMPONENTS FOR THE USA

We describe a method for creating social accounting matrices (SAMs) with detailed agricultural land rent data for any arbitrary subset of the 48 contiguous states in the USA. Data on land use and land rents from various public sources is merged with national accounts data. The method reorganizes the rental income of persons concept present in national accounts to payments to conventional primary factors of production. This method also reallocates portions of the indirect business tax account to the appropriate sales and import tax accounts. SAMs created using this method should be useful inputs into input–output or computable general equilibrium models explicitly representing a heterogeneous land market and analyzing the economic effects of agricultural, bioenergy, water and climate policies on land-use change, land rents, agricultural commodity markets, trade and households’ welfare. The method's implementation is freely available, enabling others to rapidly create SAMs with their own desired region and sector aggregations.     

中国城乡综合基尼系数测算的一种新改进

城乡综合基尼系数测算是在中国现有统计方式和数据可获得条件下的一个特殊问题,主要表现为如何在仅有城镇和农村各自的分组收入数据约束下更好地估算城乡综合基尼系数（或称城乡合一基尼系数、全国基尼系数）。针对包括城乡加权法和分层加权法等在内的子群分解法无法解决的城乡收入数据重叠难题,函数加总法通过城乡收入分布或密度函数加总形式予以化解,但既有的函数加总方法却又引发了对全国和组内最高收入的依赖问题。本文采取城乡间接洛伦兹曲线加总的形式规避了对两种最高收入的依赖,并以CHIPs2007数据为例对城乡综合基尼系数若干方法计算结果的有效性和稳健性进行了比较。此外,文章还在新改进方法的框架下进一步表达了基尼系数的城乡分解公式。     

有限合伙人、竞争者间接联结与企业创新

基于竞争性信息泄露假说，研究企业通过有限合伙人（LP）形成的竞争者间接联结对自身创新的影响。通过私募通数据库搜集数据，以电子与光电设备行业接受A轮风险投资的企业为研究对象，使用负二项分布模型进行分析，结果发现：通过LP的竞争者间接联结数量对企业创新产出有显著负向影响；通过VC的竞争者间接联结数量、LP参股VC基金的相对金额、VC的合作关系均反向调节上述关系。把竞争性信息泄露假说扩展至LP层面，提醒企业在寻求VC投资时，需要注意通过VC的竞争者间接联结以及更为隐秘地通过LP的竞争者间接联结对自身创新可能带来的阻碍。     

A diagrammatical template for business market demand estimation

This article describes a template that can help guide managers through a minefield of complex product interactions and demand drivers on the way to producing a realistic demand estimation. It is based on many years of consulting and conducting postmortems to find out what went wrong when demand forecasts have gone awry.A menu of troublesome variables that make up a rogue's gallery of the worst offending causes of estimation error are presented. The premise being, if we are aware of the potential trouble spots in demand estimation, we are likely to avoid some of the more serious problems that plague market projections.A diagrammatical template is presented that shows these troublesome variables and where they enter into the demand evaluation process. Next, the template components are introduced to show how the various product interactions and drivers that affect demand estimation are used and how they impact market projections. Throughout, a list of dos and don'ts are provided along with a sufficient number of real-life disaster stories to reinforce the issues.     

Imperfect competition,indirect tax harmonization and public goods

This paper shows that the welfare implications of indirect tax harmonization in a two-country imperfectly competitive framework, are, in general, indeterminate in the presence of public goods: Both countries can be made either worse off or better off. This holds under both the destination and origin principles of taxation and is in sharp contrast to existing results where revenue effects are not present. A consequence of this indeterminacy is that a precise evaluation of tax-harmonizing policies under both tax regimes requires an explicit consideration of the underlying preferences for private and public goods as well as the oligopolistic sectors’ relative cost structures.

Quantitative study on the urban flesh water consumption since Chinese rapid urbanization

The development of urbanization has a close relationship with fresh water resources, especially in the rapid urbanization period. By analyzing the course of the urhanization development and the experience of international urbanization development, the paper confirms the starting time of the rapid urbanization. Based on the ecotogical theory; urban fresh water consumption is composed of three types： the direct, the indirect and the induced water consumption. And the paper constructs calculation model of the indirect and the induced water consumption. Using the related statistics data, the paper makes an empirical research on the changes of the amount and structure of water consumption. Then it discusses the correlation between the water consumption and the amount of urban population, and the result shows that the amount of the water consumption arid the urban population have a remarkable correlation with the exception of the amount of the indirect water consumption, and the curves fake on quadratic functian form. Last, from the urban fimction point of view; the paper anatomizes the cause of the urban water consumption changes.
