论转型时期的社会分化与整合 总被引：1，自引：0，他引：1
王刚 《新疆财经学院学报》2006,(2):30-33
我国当前正处于急速的社会转型时期,社会结构的快速分化对原有的整合方式提出了挑战,以至于在社会分化和整合之间出现了断裂,对我国的社会稳定产生了不可忽视的影响.在新形势下,我们必须建立一种新的社会整合方式以适应社会的急速分化,维护社会的稳定. 相似文献

中国工业企业自主创新的影响因素和产出绩效研究 总被引：13，自引：0，他引：13
在当前经济转型的大背景下,中国工业企业要想在国际竞争中求得生存和发展,自主创新是关键。本文主要围绕我国企业自主创新绩效进行分析。关于企业自主创新的讨论在现有文献中并不少见,但仍存在诸多不足之处。本文提出了较为全面的研究思路来克服这些不足:在使用广义Cobb-Douglas生产函数作为企业创新绩效研究的基本方程的同时,将R&D的累积投入代理企业知识资本;着重讨论R&D内生性问题,结合我国工业企业的特点,对R&D行为决策进行建模分析找出合适的工具变量,从而避免了参数估计值的不一致性。本文实证部分使用了中国2005—2007年度近3万家产值在500万元以上的工业企业数据。研究表明:企业通过产品与技术革新等创新活动,提高了企业的产出水平,其投入产出弹性达到5.5%,修正了常规方法偏低的估计值。 相似文献

Why did some empires endure for centuries whereas others quickly fade? To approach this question, I focus on geography, namely the extent to which an empire abutted a sea. Seas could have allowed for greater opportunities for integration as well as trade with external polities. I consider historical empires from antiquity until 1922 and examine whether those empires with larger coastlines relative to their areas endured longer. Using various estimation methodologies and instrumenting for the length of the coastline, I find support that empires that were more connected to seas lasted longer. Further analysis suggests that the potential for seaways to lead to greater integration provides a stronger explanation than the potential for seas to provide a defensive barrier. 相似文献

AbstractObjective:To perform an economic evaluation of a specific brand of partially hydrolyzed infant formula (PHF-W) in the prevention of atopic dermatitis (AD) among Australian infants.Methods:A cost-effectiveness analysis was undertaken from the perspectives of the Department of Health and Aging (DHA), of the family of the affected subject and of society as a whole in Australia, based on a decision-analytic model following a hypothetical representative cohort of Australian newborns who are not exclusively breastfed and who have a familial history of allergic disease (i.e., are deemed ‘at risk’). Costs, consequences, and incremental cost-effectiveness ratios (ICER) were calculated for PHF-W vs standard cow’s milk based infant formula (SF), and, in a secondary analysis, vs extensively hydrolyzed infant formula (EHF-Whey), when the latter was used for the prevention of AD.Results:From a representative starting cohort of 87,724 ‘at risk’ newborns in Australia in 2009, the expected ICERs for PHF-W vs SF were AU$496 from the perspective of the DHA and savings of AUD1739 and AU$1243 from the family and societal perspectives, respectively. When compared to EHF-Whey, PHF-W was associated with savings for the cohort of AU$5,183,474 and AU$6,736,513 from the DHA and societal perspectives.Limitations:The generalizability and transferability of results to other settings, populations, or brands of infant formula should be made with caution. Whenever possible, a conservative approach directing bias against PHF-W rather than its comparators was applied in the base case analysis. Assumptions were verified in one-way and probabilistic sensitivity analyses, which confirmed the robustness of the model.Conclusions:PHF-W appears to be cost-effective when compared to SF from the DHA perspective, dominant over SF from the other perspectives, and dominant over EHF-Whey from all perspectives, in the prevention of AD in ‘at risk’ infants not exclusively breastfed, in Australia. 相似文献

Background:Venous thromboembolism (VTE), comprised of deep vein thrombosis (DVT) and pulmonary embolism (PE), is commonly treated with a low-molecular-weight heparin such as enoxaparin plus a vitamin K antagonist (VKA) to prevent recurrence. Administration of enoxaparin?+?VKA is hampered by complexities of laboratory monitoring and frequent dose adjustments. Rivaroxaban, an orally administered anticoagulant, has been compared with enoxaparin?+?VKA in the EINSTEIN trials. The objective was to evaluate the cost-effectiveness of rivaroxaban compared with enoxaparin?+?VKA as anticoagulation treatment for acute, symptomatic, objectively-confirmed DVT or PE.Methods:A Markov model was built to evaluate the costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios associated with rivaroxaban compared to enoxaparin?+?VKA in adult patients treated for acute DVT or PE. All patients entered the model in the ‘on-treatment’ state upon commencement of oral rivaroxaban or enoxaparin?+?VKA for 3, 6, or 12 months. Transition probabilities were obtained from the EINSTEIN trials during treatment and published literature after treatment. A 3-month cycle length, US payer perspective ($2012), 5-year time horizon and a 3% annual discount rate were used.Results:Treatment with rivaroxaban cost $2,448 per-patient less and was associated with 0.0058 more QALYs compared with enoxaparin?+?VKA, making it a dominant economic strategy. Upon one-way sensitivity analysis, the model’s results were sensitive to the reduction in index VTE hospitalization length-of-stay associated with rivaroxaban compared with enoxaparin?+?VKA. At a willingness-to-pay threshold of $50,000/QALY, probabilistic sensitivity analysis showed rivaroxaban to be cost-effective compared with enoxaparin?+?VKA approximately 76% of the time.Limitations:The model did not account for the benefits associated with an oral and minimally invasive administration of rivaroxaban. ‘Real-world’ applicability is limited because data from the EINSTEIN trials were used in the model. Also, resource utilization and costs were based on the US healthcare system.Conclusion:Rivaroxaban is a cost-effective option for anticoagulation treatment of acute VTE patients. 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

Financial management in agricultural enterprises is affected by a range of factors that are not present in other sectors. One of the factors that affect the performance of enterprises is the legal or organizational form of the business. In Slovakia, the specific structure of farms is different from that of almost any other member state of the European Union. The aim of this paper is to evaluate the disparities in the financial performance of agricultural enterprises according to the legal form. We analysed and compared two groups of agricultural entities, agricultural cooperatives and business companies, for the period from 2005 to 2014. Based on an analysis of the differences using mathematical and statistical methods, we can conclude that the legal forms are distinguished in all monitored parameters and our hypothesis on the differences in economic performance of agricultural entities according to legal form was confirmed. 相似文献
