我国上市公司盈余管理行为的实证分析   总被引:5,自引:2,他引:5  
我国证券市场存在较为严重的盈余管理现象.针对该现象,本文从盈余管理动机出发,分析我国上市公司盈余管理的行为特征.本文采用管理后盈余分布法,研究了我国上市公司2001年至2003年净资产收益率(ROE)的分布特征,发现我国上市公司仍然存在很强的盈余管理动机,而且我国上市公司盈余管理的行为受到政府监管的影响.最后,本文在实证研究的基础上提出了治理盈余管理的几点建议.  相似文献

有关刘孝标《广绝交论》的写作时间,学术界主要有天监七年、天监九年两种观点。考察刘孝标在天监年间的行迹不难发现,天监十一年是刘孝标生平思想变化的重要转折点,以此为界,他由之前的汲汲于仕途功名彻底转向拒弃名利、向往隐逸。这一思想心态的蜕变,是《广绝交论》一文的基本创作前提,该文即作于此年。  相似文献

Since the seminal research of O'Reilly, Karen [2000. The British on the Costa del Sol. London: Routledge] and King, Russell, Anthony Warnes, Allan Williams [2000. Sunset Lives: British Retirement Migration to the Mediterranean. New York: Berg Publishers] about British citizens on the Costa del Sol there has been a surge in the publication of lifestyle migration papers, books and research. Nonetheless, there is a part of the lifestyle migration process that has been rarely explored: a return move to the country of origin following retirement migration. Research has indicated a broad increase in the number of older British returnees, yet there has been no substantive research on the topic. This paper therefore attempts to fill this gap by using Spanish registry data to examine the number of British retirees since 2009 who have returned to the UK. In addition, the results of an electronic survey to older British people in Spain are presented which suggest that considerable numbers of British citizens aged over 55 living in the Northern Costa Blanca are likely to return in the next few years. These data therefore indicate the relevance of return migration from Spain to the UK as a significant issue to the academic community as well as to British and Spanish policy-makers.  相似文献

This article proposes that there is added value in moving beyond isolated studies of return-related migration policies in order to consider both deportations and so-called assisted voluntary returns under the common heading of ‘state-induced returns’. Based on official documents and interviews with staff members of the United Nations High Commissioner for Refugees and the International Organisation for Migration, it argues that international actors working in the field of migrant return engage in a type of task-sharing that goes beyond functional complementariness. With regard to the return of rejected asylum seekers, for instance, they legitimise each other's engagement as well as the overarching return objectives of governments, and are, therefore, involved in norm-building regarding the acceptability of state-induced returns. In addition to setting certain minimum standards regarding states' treatment of their immigrant population, international actors assist states in upholding control over them. Rather than merely replacing state-led regulation, international actors thus support domestic governments in reaching their migration control objectives, and thereby contribute to a stabilisation of state sovereignty in the governance of migration.  相似文献

Despite documented benefits of remanufacturing, many manufacturers have yet to embrace the idea of tapping into remanufactured‐goods markets. In this article, we explore this dichotomy and analyze the effect of remanufacturable product design on market segmentation and product and trade‐in prices by studying a two‐stage profit‐maximization problem in which a price‐setting manufacturer can choose whether or not to open a remanufactured‐goods market for its product. Our results suggest that it is optimal for a manufacturer to design a remanufacturable product when the value‐added from remanufacturing is relatively high but product durability is relatively low and innovation is nominal. In addition, we find that entering a remanufactured‐goods market in and of itself does not necessarily translate into environmental friendliness. On the one hand, the optimal trade‐in program could result in low return and/or remanufacturing rates. On the other hand, a low price for remanufactured products could attract higher demand and thereby potentially result in more damage to the environment. Meanwhile, external restrictions imposed on total greenhouse gas emissions draw criticism in their own right because they risk stifling growth or reducing overall consumer welfare. Given these trade‐offs, we therefore develop and compare several measures of environmental efficiency and conclude that emissions per revenue can serve as the best proxy for emissions as a metric for measuring overall environmental stewardship.  相似文献
