上市公司职业经理人薪酬与企业绩效关系的实证研究   总被引:4,自引:0,他引:4  
本文主要讨论了我国上市公司职业经理入薪酬变动与企业绩效变动的关系。本文选取了2002年和2003年的上市公司年报中披露的业绩和职业经理入薪酬的数据,利用线性回归和相关分析法检验了我国上市公司职业经理入薪酬的激励制约机制。研究发现,职业经理入的薪酬变动与上年业绩相关性显著,并且随着经理入是否持股、国有股比例和公司所处地域的影响。而职业经理入本年薪酬变动与本年业绩变动的关系不明显,说明我国的激励机制有待完善。而且,职业经理入薪酬下降时导致本年业绩的下降,说明薪酬的制约机制有待建立。  相似文献

资源在企业的生存、发展、绩效等方面扮演着重要的角色.作为企业一种重要的资源存在形式,组织冗余资源在企业中所起的作用不容忽视.然而,不同学者对冗余资源的作用有不同的理解,既有积极的观点也有消极的观点,这种差异主要是受到研究情境和冗余资源自身类型的影响.冗余资源最主要的作用就是能够缓冲环境变化给企业带来的冲击,保护企业的技术核心,给管理者提供较大的管理弹性,促进企业创新行为和组织变革的发生,帮助企业适应环境.  相似文献

We propose an implementable portfolio performance evaluation procedure that compares a portfolio with respect to the portfolios constructed by an infinite number of Malkiel’s blindfolded monkeys, or equivalently the whole enumeration of all possible portfolios. We argue that this approach exhibits two main advantages. First, it does not require any benchmark portfolios because a portfolio is being compared to an infinite number of portfolios. Second, it is market condition invariant. Since the market conditions are already reflected in the portfolio performances of an infinite blindfolded monkeys, our measure of portfolio performances is invariant to volatile market conditions.  相似文献

This research contributes to the debate about the relevance of Industry 4.0 technologies in improving environmental performance in the manufacturing industry. We employed a qualitative–quantitative approach in which 19 Italian operations managers were interviewed and 260 managers responded to an online questionnaire. The effects of various technologies were ranked using ordinal regression. Comments and suggestions gave context to the quantitative results. Sensors, radio-frequency identification, artificial intelligence and analytics were found to be most relevant in improving environmental performance, whereas simulation software contributed moderately. Additive manufacturing, cobots, robots, automated mobile robots and automated guided vehicles had a negative effect, augmented reality had no effect and other technologies indirectly affected environmental performance. We also found a lack of knowledge and application as well as scepticism about technologies such as artificial intelligence and augmented reality. Finally, there was concern about the disposal of electrical and electronic waste produced by these technologies.  相似文献

Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation.  相似文献

This is the first study to examine the post-IPO stock price performance by differentiating between IPOs and three types of RLBOs (i.e. public-to-private (or re-IPOs), division-to-private, and private-to-private deals). We document that public-to-private RLBOs outperform their industry rivals, IPOs, mature firms in comparable industries, and a propensity-score matched control group for up to five years post-offering. Further, we document that, within RLBOs, public-to-private RLBOs, outperform private-to-private and division-to-private RLBOs. We also find support for the underwriter signaling effect for public-to-private RLBOs. Our analysis identifies for the first time what private period restructuring activities contribute to superior post-re-IPO stock price performance. Further, the beneficial effects of private period restructurings are enhanced for deals associated with prestigious underwriters. Our findings suggest that first IPOs and re-IPOs differ substantially in term of post-offer performance, the impact of prestigious underwriters on performance, and performance over time.  相似文献

为研究单钢板-混凝土组合板在公路桥梁中的应用,提出一种新的钢板与混凝土板组合形式。通过对其进行仿真模拟结合静力试验,研究其裂缝发展模式和破坏形态,分析该模式组合板受弯承载性能。试验结果表明:试件破坏模式为弯剪混合破坏,在试验过程中,试件截面纵向应变沿组合板高度上基本符合平截面假定,在破坏前有明显的变形特征,且承载性能较好。可见该形式的组合板基本能满足使用需求,对实际工程组合板的选型有一定的参考意义。  相似文献

This study looks at the influence of cyclical fluctuations of the consumer confidence index (CCI) and the volatility index (VIX) as early-warning indicators of the variations in restaurant performance. The industry has traditionally focused on past data and on microeconomic influences to anticipate its future performance, a procedure that does not consider possible cyclical fluctuations in restaurant performance metrics. These fluctuations are driven by sentiments of consumers and investors. The study uses the cyclical component of the applied data, followed by unit root and cointegration testing, with subsequent application of the Limited Information Maximum Likelihood technique. The results show both indicators have an effect on restaurant performance, where VIX has an impact on the current, expected, and overall restaurant performance, while the CCI’s influence is only partial (current performance). Policy-makers and planners could benefit from anticipating features of indicators to assess and steer the future performance of the restaurant industry.  相似文献

对于家族企业,实际控制人和家族成员的意志会影响到公司决策,本文考察了具有亲缘关系的家族成员涉入管理职位对公司价值产生的影响,通过对我国沪深两市家族上市公司数据的实证研究,得到以下结论:(1)家族企业实际控制人涉入管理职位与公司绩效正相关;(2)家族其他成员涉入管理职位与公司绩效正相关;(3)以家族涉入者数量及其亲缘关系为测量变量的家族涉入水平指标与公司绩效负相关;(4)家族企业实际控制人拥有的公司控制权与现金流权偏离系数与公司绩效负相关。  相似文献
