SARS危机反映了当前环境问题日渐国际化的趋势,其根源是资源紧缺和经济全球化之间的矛盾。面对这一问题,各国应通力合作、寻求对策,实现环境保护的国际合作。但环境责任在各国间的分配问题阻碍了国际环境合作的进展。本文指出,基于环境和国力的全球合作机制可合理分配各国的代际责任和代内责任,有利于促进环境保护的国际合作,是一种可行的环境保护国际合作模式。要实现这一目标,首先要各国在代际和代内责任的问题上达成共识,二是要增加国际机构、国际公约对合作各方的约束力。  相似文献

企业是开展创新活动的重要主体,加强企业研发经费投入对提升企业技术创新能力至关重要。本文基于《欧盟产业研发投资记分牌(2019)》和调研数据,从研发经费投入及结构视角分析了我国企业创新活动现状,并与世界主要创新型国家进行了国际比较分析。研究发现:我国企业研发经费投入规模不断扩大,企业已经是研发经费投入主体和执行主体;相比国有企业,民营企业更具研发投资动力,是企业研发经费投入主体;我国企业研发经费投入增速较高,但研发经费投资规模和强度低于世界主要创新型国家;我国企业科学研究经费布局明显低于世界主要创新型国家,严重制约企业自主创新能力提升;我国企业基础研究占比偏低与创新特性、企业使命、发展阶段、企业能力、体制机制等因素有关,新时代应重点引导和激励更多企业向"爱迪生象限"和"巴斯德象限"跃升。  相似文献

Several investment-repatriation strategies are added to the standard model of a multinational in which an affiliate is located in a low-tax country and is limited to two alternatives: repatriating taxable dividends to the parent or investing in its own real operations. In our model, affiliates can invest in passive assets, which the parent can borrow against, or in related affiliates which can be used as vehicles for tax-favored repatriations. We show analytically how the availability of alternative strategies can effect real investment throughout the worldwide corporation. We use firm level data for US multinationals to test for the importance of alternative strategies. The evidence is generally consistent with the theory, particularly the strategies using related affiliates.  相似文献

洗钱犯罪具有诸多上游犯罪,腐败犯罪是其中之一。腐败犯罪,特别是跨国腐败犯罪,日益演化成为跨国洗钱犯罪。犯罪行为人利用国际金融快速便捷的汇兑工具,实施转移腐败赃款的活动。通过跨国洗钱活动,可以使犯罪分子获取大量的现金,并进而从事经营活动,聚敛更多的非法财产,获取更多的经济资源,从而为进一步实施腐败活动提供经济支持。为此,国际社会给予高度重视,在腐败资产追回和预防腐败资产转移目标下,探讨反洗钱国际合作,以及犯罪资产分享等理论和实践问题,为腐败资产追回和预防腐败资产转移探索国际合作途径,提高反腐败国际合作成效提供方法上的参考。我国为研究实施《联合国反腐败公约》,投入较大的精力,成立了国家预防腐败局,并广泛开展反腐败国际合作,推动实施《联合国反腐败公约》的步伐。本文就围绕以上问题,从反腐败国际合作实践角度,运用实证思考方法加以研究,以期为反腐败调查、追回腐败资产、开展反洗钱合作提供总结与建议性思想材料。  相似文献

This paper assesses the United Nations Development Program’s (UNDP) Gender-Related Development Index (GDI). Although the GDI has increased attention on gender equality in human development, it suffers from several limitations. A major problem is that it conflates relative gender equality with absolute levels of human development and thus gives no information on comparative gender inequality among countries. Using the same indicators as the GDI, the paper constructs a Relative Status of Women (RSW) index, which demonstrates how using a measure of gender equality that abstracts from levels of development results in very different country rankings. However, the RSW is not an ideal measure of gender inequality. The GDI indicators are not the most appropriate ones for measuring gender inequality and hence both the RSW and the GDI have limited validity. The paper concludes by offering a conceptual framework that provides the basis for an alternative measure of gender inequality.  相似文献

国际油价波动对经济增长的影响——基于中国的实证分析   总被引:4,自引:0,他引:4  
基于1990年1月至2009年3月的月度数据,本文实证分析了我国经济增长与国际石油价格之间的长期变动关系,其特点在于,采用稳健性较强的T-Y因果检验来分析油价与经济增长的Granger因果关系,同时,运用非对称协整技术以考察油价与经济增长之间的非线性关系。研究发现:①长期中油价是我国经济增长的单向Granger原因;②油价与我国经济增长之间存在非对称协整关系,油价上涨对经济活动的负面影响大于油价下跌的积极影响。基于中国经济运行的实际,本文还分析了实证结果背后的原因,并提出当前国际金融危机背景下,油价呈下跌趋势,需抓住有利时机,动用外汇储备,大力购入石油资源,建立起石油战略储备;在经济复苏、油价上涨时,可以启动石油战略储备来减少石油供应冲击,从而有助于及时保证我国经济平稳快速增长的政策建议。  相似文献

Cotton plays a vital role in the Egyptian economy by meeting domestic and export demands,contributing significantly to agriculture,industry,export earnings,and providing a cash income to roughly one million small farmers.This paper examines the competitiveness of Egyptian cotton exports(ECE) in the international market during the period 1990-2006.It mainly aims at investigating the trends in cotton exports over the studied period,analyzing the competitive position of Egyptian cotton by employing several economic and trade indices,and identifying the key factors that influence Egypt's cotton exports to the world.The results revealed that the total quantity of ECE has fallen from 196.8 thousand tons in 2003 to 87.2 thousand tons in 2006.It also shows a high degree of geographic concentration of ECE,into India,Italy,the Republic of Korea,and Japan.Together,these markets imported about 50%of ECE during 1990-2006.The competitive advantage of Egyptian cotton would appear dependent on quality not price.Japan,the Republic of Korea and Italy presented the most stable markets for ECE.Linear regression analysis suggests that a one percent increase in the Egypt-to-USA export price ratio leads to a decrease in ECE by about 27.8 thousand tons.Such analysis has also shown a positive and significant effect of the World Trade Organization on ECE.  相似文献

Abstract

Background:

Many countries have various requirements for local economic analyses to assess the value of a new health technology and/or to secure reimbursement. This study presents a case study of an economic model developed to assess the cost-effectiveness of posaconazole vs standard azole therapy (fluconazole/itraconazole) to prevent invasive fungal infections (IFIs), which was adapted by at least 11 countries.

Methods:

Modeling techniques were used to assess the cost-effectiveness of posaconazole vs fluconazole/itraconazole as IFI prophylaxis in patients with acute myelogenous leukemia or myelodysplastic syndromes and chemotherapy-induced neutropenia. For the core model, the probabilities of experiencing an IFI, IFI-related death, and death from other causes were estimated from clinical trial data. Long-term mortality, drug costs, and IFI treatment costs were obtained from secondary sources. Locally changed parameters were probabilities of long-term death and survival, currency, drug costs, health utility, IFI treatment costs, and discount rate.

Results:

Locally adapted cost-effective modeling studies indicate that prophylaxis with posaconazole, compared with fluconazole/itraconazole, prolongs survival, and, in most countries, is cost-saving. In all countries, the model predicted that prophylaxis with posaconazole would be associated with an increase in life-years, with increases ranging from 0.016–0.1 life-year saved. In all countries, use of the model led to posaconazole being approved by the appropriate reimbursement authority.

Limitations:

The study did not have power to detect differences between posaconazole and fluconazole or itraconazole separately. The risk of death after 100 days was assumed to be equal for those who did and did not develop an IFI, and equal probabilities of IFI-related and other death during the trial period were used for both groups.

Conclusions:

A core economic model was successfully adapted locally by several countries. The model showed that posaconazole was cost-saving or cost-effective vs fluconazole/itraconazole and led to positive reimbursement listings.  相似文献

The identification of the causal effects of educational policies is the top priority in recent education economics literature. As a result, a shift can be observed in the strategies of empirical studies. They have moved from the use of standard multivariate statistical methods, which identify correlations or associations between variables only, to more complex econometric strategies, which can help to identify causal relationships. However, exogenous variations in databases have to be identified in order to apply causal inference techniques. This is a far from straightforward task. For this reason, this paper provides an extensive and comprehensive overview of the literature using quasi‐experimental techniques applied to three well‐known international large‐scale comparative assessments, such as PISA, PIRLS or TIMSS, over the period 2004–2016. In particular, we review empirical studies employing instrumental variables, regression discontinuity designs, difference in differences and propensity score matching to the above databases. Additionally, we provide a detailed summary of estimation strategies, issues treated and profitability in terms of the quality of publications to encourage further potential evaluations. The paper concludes with some operational recommendations for prospective researchers in the field.  相似文献
