企业财务绩效评价方法研究 总被引:1,自引:0,他引:1
证券市场的不完善,监管制度的不健全使得我国中小投资者不能认识到上市公司的真实情况,自身利益得不到保障.为改变中小投资者利益受损的现状,引导投资者运用科学的方法辅助投资决策,有必要建立一套简单易用、便于理解、经济有效的绩效评价体系.本文正是以此为出发点,借鉴沃尔比重评分法,提出一套企业绩效评价方法.为充分利用原始数据的信息量,改进传统综合评价的主观性缺陷,本文运用Spss11.0统计软件中相关分析法进行指标的选取,运用变异系数法确定权数来改进沃尔比重评分法.并运用该方法体系对我国家电业上市公司进行实证分析评价.评价结果表明该体系简单易懂,财务指标容易获得,适合中小投资者使用. 相似文献

投入产出法在高校绩效评价中的运用 总被引:1,自引:0,他引:1
投入产出法以其含义直观易于理解、方法简单易于操作的优势,已被运用于高校绩效评价。投入产出法通过比值反映部门绩效大小,蕴含着经济学中的生产力观点,而且它还是数据包络分析法推导的基础,满足了绩效评价的科学性。采用投入产出法需要在建构指标体系时尽量全面地反映高校办学活动的输入、输出特点,充分考虑所选择指标的可采集性等约束条件,并寻找相对最优的权重确定方法。 相似文献

Government policy stresses partnership as a critical organizational form of the future to support the development of schooling. This article uses intergroup conflict and gaming theory to analyse data from one partnership. The views of young people and staff are explored to establish the nature and extent of conflict and its impact on the partnership. Gaming theory is used to investigate the engagement and expectations of organizations in the partnership. The article challenges Government rhetoric that suggests that as experience and trust grow, partnership will overcome the barriers which exist as a legacy from previous more competitive and isolationist cultures, to the benefit of service users. It further suggests that the availability of adequate resources alone, if ever achieved, would not in itself create the conditions for successful partnership. Far more attention is required to be given to the complex range of conditions which might support partnership and increase the possibility that the interests of learners would not be subordinated to those of organizations. 相似文献

A number of psychometricians have suggested that parallel analysis (PA) tends to yield more accurate results in determining the number of factors in comparison with other statistical methods. Nevertheless, all too often PA can suggest an incorrect number of factors, particularly in statistically unfavorable conditions (e.g., small sample sizes and low factor loadings). Because of this, researchers have recommended using multiple methods to make judgments about the number of factors to extract. Implicit in this recommendation is that, when the number of factors is chosen based on PA, uncertainty nevertheless exists. We propose a Bayesian parallel analysis (B-PA) method to incorporate the uncertainty with decisions about the number of factors. B-PA yields a probability distribution for the various possible numbers of factors. We implement and compare B-PA with a frequentist approach, revised parallel analysis (R-PA), in the contexts of real and simulated data. Results show that B-PA provides relevant information regarding the uncertainty in determining the number of factors, particularly under conditions with small sample sizes, low factor loadings, and less distinguishable factors. Even if the indicated number of factors with the highest probability is incorrect, B-PA can show a sizable probability of retaining the correct number of factors. Interestingly, when the mode of the distribution of the probabilities associated with different numbers of factors was treated as the number of factors to retain, B-PA was somewhat more accurate than R-PA in a majority of the conditions. 相似文献

The swift nature of school reform enacted by the new Conservative-led coalition government has sparked debate over the future of state education in Britain. While the government rhetoric suggests a decisive break with past policies, there is evidence to suggest that these reforms constitute the next stage of a long revolution in education reform, centred around neoliberal market discourse. In the following paper, I examine the current government’s education policy discourse and, by employing techniques of post-structuralist discourse analysis, reveal the government’s attempts to rearticulate education around the logics of market, responsibilisation and self-esteem, which act to shift responsibility for social problems from the state to the individual. Furthermore, I shall argue that such rearticulation has been coupled with an ideological fantasy of ‘empowerment’, which conceals the subordination of actors to these neoliberal logics by constituting the parent and, more recently, the teacher as powerful actors who have been freed from legal and bureaucratic constraints forced upon them by central government. 相似文献
