Two methods, theoretical analysis and calculation and Monte Carlo simulation, are used for the evaluations. By theoreti- cal analysis and calculation, frequency efficiency equation of a relay is introduced and numerical results are calculated. Monte Carlo simulation results also verify that the calculation method is reasonable. The evaluation shows that a relay can increase system performance to a certain level if it is designed appropriately, otherwise it will be harmful for the system performance, even to reduce it.展开更多

This paper is to represent how the company Sichuan Ertan Industrial Corporation （SEICO）, design performance evaluation system to improve its efficiency and effectiveness and satisfy customers＇ needs with the help of BSC principles and methodology. It is found from this case study that the key steps to design performance evaluation system are to： （1） link strategy and performance measurements at company-level; （2） decompose them into all the members in all the units at all the levels of that company; and （3） tie them to an incentive plan. Those steps have not been detailed in publications by Kaplan and Norton.展开更多

The authors use factor analysis, path analysis, and regression model to examine the effects of CAS adoption on the relationship between environmental uncertainty and organizational performance. The findings reveal that the adoption level of CAS is positively associated with organizational characteristics, environmental uncertainty, and organizational performance, and the usage of CAS has a statistically significant mediating effect on the relationship between environmental uncertainty and organizational performance. This paper will be significant to business managers in the decision to adopt CAS.展开更多

This paper examines the impact of the use of information systems （IS） and strategic organization knowledge （SOK） on firm performance in 150 Brazilian companies. The study uses partial least squares structural equation modeling （PLS-SEM） and establishes models to express the relationship among the constructs examined. The study identifies that the direct influence of 1S use on performance is moderately significant. However, when mediated by orientation strategy, the total effect of IS use on firm performance is demonstrated to be highly significant. The model explains 54% of the variability of firm performance and confirms IS use as a fundamental resource to support strategic business processes.展开更多

An unclear understanding of the various issues often results in improper handling counterproductive. Thus, we should analyze human resource performance management problems and their causes, and only on this basis can we establish and implement effective hunlan resource management system dynamic performance during the difficulties and the main factors that should be considered to elaborate.展开更多

The antecedents of green value chain implementations were considered from four dimensions namely regulations, public concerns, expected competitive advantage and top management commitment; green value chain initiatives were considered from three dimensions namely green primary activities, green internal support activities and green external support activities; the results of green value chain implementations were considered from two dimensions namely economic performance and socio-ecologic performance. A model was created according to the objectives of the study and hypotheses were formed. Multiple regression analyses were performed to investigate the relationships between the antecedents and initiatives of green value chain implementations. A relationship was not observed between green primary activities and economic and socio-ecologic performance. While a positive relationship was observed between green external support activities and economic performance, a positive relationship was observed between green internal support activities and both economic and socio-ecologic performance.展开更多

While some believe that privatization is the only solution to SOE inefficiency, others contend that privatization will lead to serious loss of state assets without resolving the problem. This paper examined how performance evaluation system contributed to the innovation and profitability of central SOEs after the implementation of the revised Interim Measures for Assessment of the Operational Performance of Persons in Charge of Central Enterprises in 2009. Using this revision as a natural experiment, this paper conducted a difference-indifference analysis and discovered a significant improvement in the innovation of central SOEs after the implementation of the new policy as compared with private firms not affected by this system. Moreover, the revised performance evaluation system significantly improved the marginal contribution of innovation to corporate value. The above test result indicates that SOEs may become more efficient solely by altering executive incentives without privatization. In this sense, privatization may not be the only solution to SOE inefficiency. This paper offers theoretical insights on the controversies regarding SOE privatization and helps enrich relevant literature on corporate incentives and innovation.展开更多

The paper aims to investigate the influence of corporate governance of the banks that operate in the cooperative credit system on performance and quality of loans, over the years 2010-2011-2012. In order to achieve this aim, the following research hypotheses have been formulated： There is a statistically significant relationship between the size and the structure of the board and banks Performance operating in the cooperative credit system; there is a statistically significant relationship between the size and structure of the board and the credit quality of banks operating in the cooperative credit system. The analysis is conducted on a sample composed of 48 Italian banks, divided into 24 cooperative banks and 24 popular banks. The sample is made up of banks from all over Italy and very different in terms of dimension. For the sample construction, data relative to governance of banks were collected from the balance sheets in the period from June to August 2014. Financial-economic data were collected from the Financial Statements and from Bankscope database. The methodology of analysis is based on multivariate OLS （ordinary least squares） regression models. The main results refer to the presence of significant relationships between board dimension and the quality of loans and among the number of committees and performance and the quality of loans. The presence of a significant and negative relationship between the board dimension and the ratio of impaired loans to gross loans indicates the possibility that enlargement of board dimension allows a better quality of loans. The presence of a positive relationship between the number of committees and the ratio of impaired loans to gross loans signals the possibility that a greater number of committees can produce a worse quality of loans. The presence of a negative relationship between the number of committees and bank performance suggests to limit and manage the complexity of governance in banks operating in the cooperative credit system.展开更多
