会计目标不仅是一个重要的理论问题,亦是一个重要的实际问题。美国是世界上研究会计目标最早、取得研究成果最丰富的国家之一。从美国会计学会1966年发表基本会计理论研究公告算起,美国从事会计目标研究已有30余年的历史。美国会计学会、会计原则委员会、特鲁布罗德委员会、财务会计准则委员会都对会计目标的研究作出过重要贡献,形成了像基本会计理论公告、APB第4号报告、特鲁布罗德报告和企业财务报告的目标等一系列研究成果。通过对美国会计目标研究历史的分析,我们从中可以得到如下三点启示: 第一,会计目标的研究与对会计本质的认识密不可分; 第二,会计目标研究应密切联系一定的社会经济环境; 第三,会计目标研究应采取理论分析与实证研究相结合的方法。  相似文献

The structure and financing of science and technology activities are undergoing a slow, but profound, change. This change can be briefly characterized as a shift from relying and supporting public science to a stronger emphasis on “market-based” incentives for science and technology. In this paper we analyze this shift in a historical perspective, discussing both the theoretical explanations and the empirical trends of the ongoing change. While we do not claim to provide a comprehensive and exhaustive identification of the causes of this shift, we argue that it is largely driven by the perception of a shift of the U.S. policy towards market-based, rather than publicly supported, incentives for science and technology. This, in turn—given the strong economic performance of the United States over the 1990s—has influenced policies in most OECD countries, especially in Europe.We conclude by analyzing the evolution of research in U.S. higher education and find two major trends: an increasing diversity in the number of institutions of different types other than universities and a steady and continuous public funding of the leading U.S. universities. This has allowed the construction of an infrastructure now used largely by the private sector, but it also noted that the United States has not compromised public support for core areas or in those fields in which there is a clear perception that market incentives are not sufficient for meeting the strategic targets of the U.S. policy. The implication is that there is a considerable policy diversity in the U.S. practice and that all aspects of this diversity should be considered when using the United States as a reference.  相似文献

This paper summarizes the results of the first systematic, geographically-specific efficiency assessment of the U.S. experience with national environmental standards and with alternative approaches to establishing those standards. This ex-post evaluation assessed the net benefits that resulted from EPA's regulation of conventional air and water pollutants from the pulp and paper industry between 1973 and 1984. The paper compares the benefit-cost efficiencies of the three dominant regulatory approaches: technology, ambient, and benefits. Unlike previous studies, which assessed benefits and costs on a national basis, the study estimates both costs and benefits on a facility-by-facility basis. The analysis shows how the efficiency of national environmental regulations can vary dramatically at local levels. The authors conclude that the technology-based standards for water pollution management failed as an efficient environmental strategy. The costs clearly exceeded the benefits in the aggregate, as well as in the specific in most situations. Benefits exceeded costs at only 11 of the 68 mills investigated. The ambient based standards for air pollution management succeeded as an environmental strategy in the aggregate, but succeeded in the specific for only one-third of the mills (22 of 60 mills). The benefits-based standards for air pollution management also succeeded in the aggregate as well as in the specific for about one-half of the mills. Benefits exceeded costs at 29 of the 60 mills investigated. The results of the study point to two major conclusions. First, a regulatory policy that is based on some measure of environmental results, either ambient-based or benefits-based, will be more efficient than a policy that ignores environmental results. Second, truly efficient policies for reducing environmental risks require pollution mitigation decisions that take into account local conditions. These include not only the changes in local ambient conditions, but also the number of people who will benefit from pollution reduction decisions. This latter conclusion suggests that national environmental standards per se may be inefficient.Dr. Luken is currently Senior Environmental Advisor to the United Nations Industrial Development Organization (UNIDO) in Vienna, Austria.

目的 乡村衰败是国内外城市化进程中呈现的一种普遍现象,在城市化推进过程中,城市繁荣与乡村衰败形成了鲜明对比。由于较早进入工业化和城市化阶段,国外发达国家及地区的乡村衰败出现较早,其应对乡村衰败的经验丰富且相对成熟,梳理发达国家及地区乡村衰败的应对经验及理论模式对中国乡村振兴战略的实施具有一定借鉴意义。方法 文章首先回顾了美国城市化发展历程,分析其城乡人口流动最新趋势,从人口、就业及物质设施等方面梳理城市化背景下美国乡村衰败的基本特征,总结其应对乡村衰败实践经验及理论探讨。结果 从美国的案例中可以看出,城市对乡村的发展至关重要,至少可从三个方面获得解释。结论 美国乡村衰败应对历程对其他国家乡村问题解决具有多个经验启示,具体包括从城市化历史进程中去理解乡村衰败现象、重视城市对乡村的带动及反哺作用、承认乡村的地域差异并采取不同应对措施、重视互联网技术在乡村振兴中的作用等等,上述经验启示对中国乡村振兴战略实施具有一定借鉴意义。  相似文献

Although many studies have analyzed the behavior of high‐skilled migration to the United States, few have focused on the escalating migration of Mexican entrepreneurs, and particularly on the determinants of this kind of high‐skilled migration. This article addresses this gap through a qualitative approach conforming to quantitative procedures, based on 20 in‐depth interviews applied to Mexican entrepreneurs working and/or living in the United States. Theoretically, a mixed‐embeddedness approach guides this research because it allows examining both the individual characteristics of Mexican entrepreneurs, and the influence of the home and host countries' institutional contexts on their business endeavors. Findings revealed Mexico's institutional weaknesses, such as insecurity, corruption, and bureaucracy, are important drivers of migration but so are the perception of a friendly U.S. fiscal system, the search for a better quality of life, and the appeal of a more transparent business environment.  相似文献

本文通过建立人民币双边实际汇率与中国对美出口的分析模型,运用协整分析、误差修正模型和脉冲响应函数进行实证研究。结果表明:期望通过人民币升值来解决中美贸易失衡问题的愿望很难有效实现,近年来中国对美出口的大幅增长是与美国自身经济发展的需求有较大关联的,而且这种需求有逐渐增强的趋势;短期内,对美出口的增长远胜于通过人民币升值所期望减少的出口;美国国民收入水平有拉动人民币升值的潜在作用。  相似文献

解析美国巨额贸易逆差形成的原因   总被引:1,自引:0,他引:1  
随着近年来经济全球化进程的加快,美国出现了全球所独有的巨额贸易逆差,并呈现出不断扩大的趋势,分析其贸易逆差形成的原因具有十分重要的现实意义。本文结合当今全球贸易的新特点,重点分析了美国制造业商品贸易的变化,指出美国信息产业等诸多产业已经转移到新兴工业化国家,尤其是亚洲国家。这种全球性的产业转移和技术扩散引致美国制造业国际竞争力下降是其巨额贸易逆差形成和扩大的主要原因。  相似文献
