本文以2014-2017年我国沪深A股上市公司为研究样本,对上市公司实施员工持股计划与企业创新之间的关系进行了探讨。研究发现,相比未实施员工持股计划的上市公司,实施了员工持股计划的上市公司创新产出更高,员工持股计划有利于促进企业创新。进一步地,员工持股计划持有人数越多,资金规模越大,资金来源于员工薪酬及自筹资金,高管认购比例越高,锁定期越长,越能增加企业发明专利和实用新型专利申请数量,提升创新能力。员工持股计划主要通过降低代理成本、提高企业风险承担能力来促进企业创新。与国有企业相比,非国有企业实施员工持股计划更能增加企业创新产出。论文的研究结论为提高企业创新能力,建设创新型国家提供了经验证据。  相似文献

We investigate the possible predictability of firm growth in Taiwan using cross-sectional data of financial factors for the years 1997 and 2003 via principal component analysis. Our results reveal that the 18 financial variables (sales growth rate, total assets, total sales, return on assets, return on equity, gross margin, operating cost minus depreciation divided by sales plus other trading income, acid test ratio, debt–equity ratio, time interest earned, average receivables per average daily sales, inventory, average payables per average daily sales, working capital, working capital as a fraction of total assets, long-term liabilities as a fraction of total assets, and sales as a fraction of net worth of the firm) that we employ bunch together into five different financial ratios for the years 1997 and 2003 that are stable between these years. These financial factors are short-term liquidity, return on investment, long-term liquidity, firm size and capital turnover. Regressing these ratio groups (extracted principal components) on firm growth, we find return on investment in the year 1997 was positively and significantly related to firm growth, while long-term solvency was negatively related to firm growth. In addition, smaller firms tended to grow faster. By 2003, larger firms grew faster than smaller ones and short-term liquidity was positively and significantly related to firm growth, while return on investment was no longer a significant determining factor. Our findings suggest that firms that finance internally or do not rely too heavily on indebtedness may end up growing slower during boom periods but they are the ones that survive and outperform after the bust.  相似文献

Recent empirical work shows evidence for higher valuation of firms in countries with a better legal environment. We investigate whether differences in the quality of firm‐level corporate governance also help to explain firm performance in a cross‐section of companies within a single jurisdiction. Constructing a broad corporate governance rating (CGR) for German public firms, we document a positive relationship between governance practices and firm valuation. There is also evidence that expected stock returns are negatively correlated with firm‐level corporate governance, if dividend yields are used as proxies for the cost of capital. An investment strategy that bought high‐CGR firms and shorted low‐CGR firms earned abnormal returns of around 12% on an annual basis during the sample period.  相似文献

This study develops a content analysis framework that provides information on the comprehensiveness of corporate social responsibility (CSR) reporting, an important aspect of social and environmental accountability. Comprehensive reporting, as defined here, requires three types of information for each disclosed CSR item: (i) vision and goals, (ii) management approach, and (iii) performance indicators. The feasibility of the framework to assess the comprehensiveness of CSR reporting is demonstrated using the 2005 annual reports of a sample of publicly traded Belgian companies. The content analysis reveals a low level of comprehensive reporting. This finding complements those of prior studies on the completeness of CSR reporting and, therefore, feeds the debate regarding the extent to which CSR reporting can be considered a mechanism for discharging social and environmental accountability.  相似文献

Our study investigates the quality of firms’ continuous disclosure compliance during mandatory continuous disclosure reform, and whether the compliance quality is impacted by corporate governance, using the New Zealand market as the setting. We use a novel coding of different categories of disclosures (non‐routine, non‐procedural and internal), which represents the extent of proprietary insider information inherent in disclosures, to evaluate firms’ compliance quality. Our findings provide evidence that firms’ compliance quality improved after the reform, and this improvement is inconsistently impacted by corporate governance. Our findings provide important implications for regulators in their quest for a superior disclosure regime.  相似文献

The aim of this work is to study corporate governance (CG) in small and medium enterprises (SMEs) from a gender perspective. In particular, we study the participation of women in ownership, management (board and senior management) and external audit in SMEs participating in the Argentinean Securities Market. The results show that participation of women in ownership and in external audit has a significant relationship with financing decisions. However, we do not find evidence of relations among different levels of GC and gender.  相似文献

我国融资融券立易模式的制度选择分析   总被引:1,自引:0,他引:1

尽管国内各项法规已经针对融资融券业务制定了诸多细则,但具有决定意义的融资融券交易模式并未明确。本文着重分析了当前国际市场上的几种主流交易模式的操作方法,并进行了详细的对比。结合中国已有的业务细则,认为设立统一证券金融公司,能够最大程度控制风险的"单轨制专业化"模式将是中国证券市场的合理选择。  相似文献

We study the relationship between investor relations disclosure and analyst forecast properties in Australian firms, a setting dominated by small firms with limited analyst coverage and requiring continuous disclosure of price sensitive information. We find increasing disclosure in the time period investigated is associated with greater accuracy in firms disclosing fewer items. Disclosure was unrelated to forecast dispersion, possibly due to the low analyst following. In periods of uncertainty, the investor relations awards effectively discriminated quality from quantity of disclosure. These findings highlight the importance of active communication with analysts, particularly in firms providing less disclosure and during periods of uncertainty.  相似文献

This paper investigates the differential impact of positive and negative excessive managerial entrenchment on the CEO turnover-performance sensitivity, CEO compensation, and firm performance. We measure the degree of managerial entrenchment using the E-index introduced by Bebchuk et al. (2009). Our findings suggest that an increase in excess CEO entrenchment reduces the likelihood of CEO turnover due to poor performance. We also show a positive association between excessive entrenchment and CEO compensation as managers gain more power and authority when they are entrenched. On the other hand, excess CEO entrenchment has an inverse correlation with firm performance and firm value. Overall, we propose that excessive managerial entrenchment has a converse impact on board monitoring and shareholders’ welfare.  相似文献

We examine how board gender diversity is associated with biodiversity disclosures of a firm, and whether the Global Reporting Initiative (GRI) and the EU biodiversity strategy reinforce this relationship. Using institutional theory and resource dependency theory, our sample comprises 4013 firm-year observations from European corporations covering data from 2002 to 2016. We use panel regressions with country, time and industry dummy variables to analyse the disclosure of biodiversity initiatives (DBI) and logit regressions to explain biodiversity impact assessment (BIA). We find that board gender diversity is positively associated with the DBI and BIA of a firm, and that the GRI framework and the EU biodiversity strategy positively moderate this relationship. Moreover, the GRI framework and the EU strategic plan show positive relationship with the DBI, rather than BIA. Altogether, our evidence suggests that corporate boards with a higher proportion of female directors are more sensitive to the concerns of institutional pressures and respond to those concerns by increasing corporate biodiversity disclosures. Overall, we find that firms tend to comply with the GRI framework and the EU 2020 strategy by undertaking symbolic biodiversity disclosures, rather than providing a comprehensive disclosure of their impacts on biodiversity.  相似文献
