理工专业英语CET6水平汉译英测试抽样错误分析——以南昌大学为例

在20世纪70年代错误分析理论产生之后,各种类型的错误分析研究便如雨后春笋般涌现,本文以南昌大学大二理工专业高水平英语班级学生为研究对象,以大学英语四、六级新题型段落翻译为实验形式,目的是分析在这种新题型中学生容易出现的典型汉译英错误,并在教学中进行纠正、完善和提升。     

基于“6σ管理”的食品安全政府监管模式研究

在简要论证“6σ管理”对于食品安全政府监管的适应性基础上,构建了基于“6σ管理”的食品安全政府监管模式,并就其定义、测量、分析、改进、控制等工作流程和规制予以阐释,提出了政府食品安全监管“6σ管理”模式实施应注意的问题,包括注重制度和人财物等方面的顶层设计、6σ项目选择应注重问题导向机制、不能仅仅等同于做项目、把握管理工具应用的灵活性与综合性、基础数据要准确全面及时等等。     

空间效应视角下的中国省域工业技术创新效率收敛性研究

本文基于2009—2018年我国30个省份的面板数据,构建非导向、非径向且规模报酬可变的窗口MinDS超效率模型测度各省份的工业技术创新效率,采用全局莫兰指数检验省域工业技术创新效率的空间相关性,然后使用变异系数、建立空间计量模型进行σ收敛、β收敛分析。研究结果表明:我国省际工业技术创新效率的均值为0.7499,东部、中部、西部三大区域差异较明显,依次降低;10年期间东部、中部的工业技术创新效率有降有升,而西部则基本上稳定上升;省域工业技术创新效率的空间分布呈现显著的正向空间相关;全国与分区域均未出现σ收敛,但同时存在绝对β收敛与条件β收敛。本研究明晰了各省份的工业技术创新效率及其收敛性,为缩小工业技术创新效率区域差距、促进工业经济高质量发展提供现实依据与理论借鉴。     

End of double taxation: Is the policy better when announced?

This paper examines the effectiveness of the “end of double taxation” (on dividends) policy in stabilizing an economy. Both announced and unannounced policies are considered. A reduction in double taxation stimulates investment and improves welfare, but its impact on output is moderate and it has a negative effect on work hours. A temporary cut creates an investment boom but also generates an investment slump when the tax cut expires. Announcements of future tax cuts are found to have important effect on output dynamics. Agents respond to the tax policy even before it is implemented. If the tax cut is announced to be temporary, its impact on output is greatly reduced. Our study suggests that a temporary dividend tax cut is most effective in stabilizing a recession stricken economy when the policy change comes as “news” to the economy.     

Social protection assessment‐based national dialogue exercises: Cambodia,Indonesia, Thailand,Viet Nam

Between 2011 and 2013, the International Labour Organization, in collaboration with governments and several United Nations agencies working as part of the Social Protection Floor Initiative, conducted social protection assessment‐based national dialogue (ABND) exercises in Cambodia, Indonesia, Thailand and Viet Nam. The exercises were carried out in order to take stock of existing social protection realities in the respective countries, including social insurance, social assistance and anti‐poverty programmes. These inventories present a comprehensive picture of what elements of national social protection floors (SPFs) are in place, where “holes” in national floors exist, and provide a framework within which to propose recommendations for the further design and implementation of social protection provisions that guarantee at least the SPF to the entire population. This article describes the methodology for conducting ABND exercises, the situational analysis of the SPF in four countries, and the policy recommendations that were formulated for achieving basic health care and income security for children, the working‐age population and the elderly. The results of preliminary calculations of the cost of implementing proposed policy options are also outlined.     

Fiscal policy analysis in the euro area: Expanding the toolkit

The absence of historical quarterly fiscal data has limited the analysis of the macroeconomic impact of fiscal policies in the euro area, including the interactions of fiscal and monetary policies. To overcome this gap, we construct a quite disaggregated euro area quarterly fiscal database for the period 1980Q1–2012Q4, based on a rich set of input fiscal data taken from national sources. We discuss how this dataset has allowed and can allow the profession to tackle new policy-relevant research topics. We also provide stylized facts on the cyclical properties of main euro area fiscal aggregates, focusing on the recent economic crisis period.

Global loss of production capacity caused by the COVID-19 pandemic

The global economy faces a loss of production capacity among the most severe in at least the past half-century as a result of the recession caused by the COVID-19 pandemic. It will take several years of persistent investment efforts to restore the pre-pandemic level of capacity and put global output back to potential. By using a production function based on the incremental capital-output ratio, we estimate the loss of production capacity for the global economy and for the two main world locomotives, the U.S. and China. To do this, we estimate the production capacity implied in our current recession baseline and the capacity that would have existed in the absence of the pandemic (precrisis scenario). The difference between the two estimates is defined as the loss of capacity generated by the pandemic. The results also allow us to extract some policy implications in terms of mitigation measures and investment requirements.
