研究目标:揭示2000年以来中国参与全球价值链(GVC)的程度、位置、竞争力特征,以及与主要经济体在GVC中的双边联系特征。研究方法:采用新近发展的生产分解模型,从前向联系和后向联系两个视角全面分析。研究发现:中国在GVC中的国际竞争力主要体现在制造业部门,已经具备“制造强国”的基本特征,接近GVC的中上游位置。大多数国家都对中国市场形成了高度的依赖性,同时中国成长为全球中间品的最大供应国,在GVC中扮演着关键的“枢纽”角色。研究创新:在一个统一的核算框架下,本文从多重视角首次对中国参与GVC的特征做出系统性的论述。研究价值:本文对于决策部门评价中国参与GVC的成效,研判国际经济关系,制定对外经济政策具有重要参考价值。 相似文献

The paper reviews recent work on statistical methods for using linkage disequilibrium to locate disease susceptibility genes, given a set of marker genes at known positions in the genome. The paper starts by considering a simple deterministic model for linkage disequilibrium and discusses recent attempts to elaborate it to include the effects of stochastic influences, of drift, by the use of either Writht-Fisher models or by approaches based on the coalescence of the genealogy of the sample of disease chromosomes. Most of this first part of the paper concerns a series of diallelic markers and, in this case, the models so far proposed are hierarchical probability models for multivariate binary data. Likelihoods are intractable and most approaches to linkage disequilibrium mapping amount to marginal models for pairwise associations between individual markers and the disease susceptibility locus. Approaches to evalutation of a full likelihood require Monte Carlo methods in order to integrate over the large number of unknowns. The fact that the initial state of the stochastic process which has led to present-day allele frequencies is unknown is noted and its implications for the hierarchical probability model is discussed. Difficulties and opportunities arising as a result of more polymorphic markers and extended marker haplotypes are indicated. Connections between the hierarchical modelling approach and methods based upon identity by descent and haplotype sharing by seemingly unrelated case are explored. Finally problems resulting from unknown modes of inheritance, incomplete penetrance, and phenocopies are briefly reviewed. 相似文献

随着企业信息化程度的不断提高,越来越多的应用系统被应用到实际的生产工作中来。然而企业中的应用系统之间并不都是相互关联、共享资源的。为了确保系统与系统之间数据是一致的、同步的,类似于BizTalk这种中间件的应用就越发重要了。本文介绍了BizTalk是如何实现仓储管理系统与SAP之间的数据交互的。 相似文献

本文选取2000~2015年全球40支股票指数日收盘价,通过建立收益率网络和DCC MVGARCH模型波动率网络对中国股票市场国际联动性进行实证分析。研究表明,随着经济全球化的加深,全球股市收益率和波动率联动逐渐增强;全球金融危机和欧债危机期间,收益率联动网络具有小世界性;中国与全球股市长期处于割裂状态,但在全球金融危机期间与其他市场联系加强。在全球经济形势复杂多变的情况下,中国应针对性采取措施促进股市发展,以分享全球金融一体化利益。 相似文献

出口贸易的后向链接溢出效应——基于中国制造业数据的实证研究 总被引:6,自引:0,他引:6
本文利用我国1996~2003年17个制造业对16个OECD国家的出口贸易面板数据以及1997年和2002年的投入产出表,实证检验了我国出口贸易企业的水平链接溢出效应和后向链接溢出效应。结果表明,我国出口贸易企业通过向上游产业的非出口部门企业购买中间产品和服务产生了积极的后向链接溢出效应,而出口贸易企业的水平链接溢出效应并不明显。进一步的研究发现,我国制造业出口贸易的后向链接溢出主要来自于对美国和其他14个OECD国家的出口贸易企业。 相似文献

Over the past thirty years, public policy in Rome has failed to effectively address a rising level of socio-economic inequality. Indicators such as level of education or number of household members appear to be geographically concentrated and sensitive to the distance from the city centre. The hypothesis that socio-spatial inequalities strongly influence economic performance and foster political instability has been subject to numerous empirical investigations. Nevertheless, studies of specific urban contexts are not common. The absence of empirical applications at this scale is probably due to the fact that variables used for analysing the economic and social performance of regions are difficult to quantify or inapplicable at the micro level. The purpose of this paper is to examine the spatial distribution of socioeconomic inequalities in the municipal territory of Rome and to explore the conditions that account for them. We will analyse the spatial distribution of urban quality indicators and socio-economic profiles with data from different sources, aggregated at the neighbourhood level. 相似文献

“十二五”时期统筹推进城乡一体化的路径思考 总被引:2,自引:0,他引:2
"十二五"将是中国城乡一体化取得历史性突破的关键时期,要顺应城乡经济社会发展关联度显著增强的新形势,必须积极推进农村改革与城市改革实现由脱节走向互动,构建新型工农、城乡关系.这是统筹城乡发展的关键切入点.也是加快形成城乡经济社会发展一体化新格局的重要突破口.为此,要在系统把握城乡改革联动内涵的基础上,做好改革顶层设计和总体规划,着力打破农村改革对正式制度变迁的路径依赖,积极推动资源要素向农村配置,协调推进城镇化和新农村建设,切实尊重农民合法权益和首创精神.稳步推进城乡体制机制创新. 相似文献

关联方交易的实质及对会计报表信息影响的分析 总被引:2,自引:0,他引:2
本文在现行会计准则关于关联方和关联方交易及其披露规定的基础上,对关联方及关联方交易的实质进行了分析。指出了在企业的交易活动中,交易各方通过隐性的关联方交易来达到某种共同特定目的,这些交易事项并未在会计报表中真实地反映其实质,从而会直接影响会计信息的质量和信息使用者的正确决策。因此,建议企业在其会计报表中真实充分披露隐性的关联方交易。 相似文献

This research develops a framework to estimate the relative efficiency of developing countries in utilizing both their domestic and external resources to achieve the Millennium Development Goals. The analysis highlights distinct efficiency differences across lending groups and geographic regions e.g. between Sub-Saharan Africa and Latin America. The performance of regions exposed to natural disasters and political violence need to be analyzed individually and risk management ought to be an integrated part of development policy. The gap between the Millennium Development Goals and human rights approaches is then examined. Finally, we qualify a country's performance level as potentially sustainable in terms of human, social and environmental welfare, in turn searching for realistic benchmarks and intermediate targets for the relatively inefficient countries. Principal component analysis in combination with data envelopment analysis was applied to solve the problem of efficiency overestimation with multi-dimensional scaling used to present the issue graphically. In summary, the aim of this work is not to rank countries in a league table rather to provide a framework that combines economic, environmental and social issues in order to search for sustainable, pragmatic benchmarks, pushing the boundaries of the Human Development Index. 相似文献

The purpose of this study is to analyze the existing literature on human resource management (HRM) from all the research papers published in The International Journal of Human Resource Management between 2000 and 2012. The authors apply bibliometric methods to identify the main research lines within this scientific field; in other words, its ‘intellectual structure’. Social network analysis is also used to perform a visualization of this structure. The results of the analysis allow us to define the different research lines or fronts which shape the intellectual structure of research on HRM. 相似文献

Abstract After a short history of the concept of human capital (henceforth HC) in economic thought ( Section 1 ), this study presents the two main methods for estimating the value of the stock of HC – the retrospective and prospective one – with a review of the models proposed ( Section 2 ). These methods are linked both to the theory of HC investment as a rational choice ( Section 3 ), the literature analysing the contribution of HC investment to economic growth and the HC estimating method through educational attainment ( Section 4 ). The more recent literature on HC as a latent variable is also assessed ( Section 5 ) and a new method of estimation where HC is seen both as an unknown function of formative indicators and as a ‘latent effect’ underlying earned income is proposed ( Section 6 ). Section 7 concludes. 相似文献
