湖南经济周期阶段的分析与预测

根据湖南1978～2010年相关数据对湖南经济周期阶段进行分析,结果表明:1978～2010年湖南经济经历了5个繁荣时期,分别是1978～1979年、1984～1986年、1991～1993年、1995～1998年、2006～2010年,且繁荣阶段的持续性在不断增强;其余年份经济处于衰退阶段。另外,湖南经济周期阶段预测结果显示:2011～2012年经济依然处于繁荣阶段;2013～2015经济处于衰退阶段,虽然处于衰退阶段,但是其程度并不深,尤其是2015年。     

林业技术效率及其影响因素研究——基于随机前沿生产函数

文章运用随机前沿生产函数估计了林业生产投入要素劳动力和资本的产出弹性,测量了各省区2002～2009年的林业技术效率,并分析了林业技术效率的影响因素。结果表明:林业产业存在明显的技术效率损失,随机前沿生产函数的误差主要是由技术非效率引起;林业产业劳动力和资本的产出弹性分别为0.58和0.47,林业生产仍处于规模报酬递增阶段。总体上,各省区林业技术效率水平相差不大,且林业的平均技术效率水平呈现缓慢上升的趋势;森林病虫鼠害的发生率显著降低了林业技术效率,而基层林业工作站人员文化水平的提高能有效的改善林业生产的技术效率。     

基于县域的粮食安全早期预警方法研究

该文以二熟区典型粮食生产大荔县为例,根据粮食安全预警理论,结合农情监测网络试点县小麦产量时间序列、农情调查和主要小麦品种性状的信息,建立了县域小麦年度间和生长季节内关键生育期的产量预报方法。结果表明:大荔县2006～2007年度小麦播种前(年度预测)、播种～出苗期、出苗～越冬期、越冬～返青期、返青～拔节期、收获(实际产量)等6个生育时期的每667m2的产量分别为258kg、453.1kg、396kg、318.1kg、296.7kg和246kg,其中播种～出苗期、出苗～越冬期、越冬～返青期、返青～拔节期4个时期的产量安全预警系数分别为98、87、80和93,总体为绿色警示,无粮食安全风险警报,但洛河灌区和洛南灌区分别在出苗～越冬期和越冬～返青期出现了黄色警示。此方法为建立中国粮食安全与早期预警系统(CFSIEWS)探索了一条可能的途径。     

The role of international reserves holding in buffering external shocks

An extended literature analyses the accumulation foreign exchange holding observed in many developing and emerging countries since the 2000s. Empirical studies on the self-insurance motive suggest that high-reserves economies are more resilient to financial crises and to international capital inflows volatility. They show also that pre-crisis foreign reserve accumulation explains post-crisis growth. However, some papers suggest that the relationship between international reserves holding and reduced vulnerability is nonlinear, meaning that reserve holding is subject to diminishing returns. This article devotes more attention to the potential nonlinear relationship between the foreign reserves holding and macroeconomic resilience to shocks. For a sample of nine emerging economies, we assess to what extent the accumulation of international reserves allows to mitigate negative impacts of external shocks on the output gap. While a major part of the literature focuses on the global financial crisis, we investigate this question by considering two sub-periods: 1995–2003 and 2004–2013. We implement threshold VAR model in which the structure is allow to change if the threshold variable crosses a certain estimated threshold. We find that the effectiveness of reserve holding to improve the resilience of domestic economies to shocks has increased over time. Hence, the diminishing returns of foreign reserve holding stressed in the previous literature must be qualified.     

Contagion effects of sovereign credit rating revisions on the real economy: is it trade or finance?

We analyse the contagion effects of sovereign credit rating revisions on the real economy, with particular emphasis on the intensity of trade and finance channels. Our findings show that event countries that experienced rating revisions cause substantial contagion effects on the real output growth rates of nonevent countries. Nonevent countries with a high export ratio, high external debt levels, or those that are more dependent on common bank credit relative to other nonevent countries are more likely to be infected by event countries’ adverse credit shocks. The results remain after accounting for alternative real economy indicators, financial liberalization, financial crises, and economic development status.

Quantifying the relative importance of export industries in a small open economy during the great depression of the 1930s: an input–output approach

This paper provides a quantification of the relative importance of export industries in a small open economy using new data provided by input–output tables describing the Finnish economy in 1928. The Finnish analysis of the Great Depression of the 1930s has been particularly focused on the importance of foreign trade. Despite the lack of quantified evidence, it is commonly accepted that the export industries had a major role in the economic development. The basic input–output framework is extended into a production–consumption model to produce a more elaborate model that provides a quantification of changes in final demand of some key industries in the economy. Results suggest that even though the role of export industries was dominant, domestic market industries and private consumption also had a significant role in the depression.

Alternative Approaches of Physical Input–Output Analysis to Estimate Primary Material Inputs of Production and Consumption Activities

In the last few years, a number of studies have been presented that link material flow accounting and input–output analysis (based on monetary input–output tables) for the calculation of direct and indirect resource inputs for production and consumption activities. The compilation of the first physical input–output tables for some European countries in the 1990s opened new possibilities for linking physical accounting and input– output analysis. Physical input–output analysis has so far only been applied for selected materials, but it has not been used for comprehensive assessments of material requirements of economic activities. In this paper, possibilities and limits of this new input–output approach are clarified. We present and discuss a procedure similar to monetary input– output analysis and develop an alternative approach to account for primary inputs and waste otherwise not included in the analysis. Based on aggregated input–output tables for Germany, we present numerical examples intended to compare the alternative approaches of physical input–output analysis.     

Queensland State Impact and Projection Model: The Household Sector

The Queensland Impact and Projection model is an integrated input–output econometric model of the Queensland economy. Its purpose is to complement a conventional input–output model for analyzing economic impacts at the state level. This paper provides an overview of some of the methods used to model the household sector in an input–output framework, before describing the approach taken in the Queensland model. Some results which support the empirical performance of the model are also provided. It is demonstrated that the integrated model is a viable alternative and improvement on the conventional input–output model. The results are consistent with the static input–output model and conform to expectations about how the economy responds in real impact situations.     

对高职院校中全英文教学的几点思考

对于高职的学生来说全英文教学中的输入量过高 ,因而使他们失去兴趣 ,进而使课堂教学和者甚寡 ;而量体裁衣的课程准备更能收到预期的教学效果 ,循序渐进最终才能实现全英文教学的目的。
