董事会规模与公司价值关系的进一步检验——基于公司规模门槛效应的分析

对于董事会规模与公司价值之间的关系,以往的研究得出了完全不同的两种结论,分析原因可能是因为公司在确定董事会规模时很大程度上取决于公司规模大小。本研究通过检验发现,公司规模对董事会规模具有门槛效果,通过使用门槛自回归模型可以更好地解释董事会规模和公司价值之间的关系,实证研究的结果表明,在公司规模相对较小的门槛区间,董事会规模和公司价值之间存在显著的正相关关系,而在公司规模较大的门槛区间,董事会规模与公司价值之间的关系在统计上不显著,但符号上表现为负相关关系。     

论物质减量化原理在资源价值流计算中的应用

资源价值流计算是评价循环经济的一种重要方法,物质减量化原理是源于生态工业学的一个基本原理,将物质减量化原理与资源价值流计算相结合,不仅是实施循环经济的本质要求,还可以深入企业内部各生产流程,解析其各阶段实施减量化前后企业经济、环境效果的对比。本文以某原生铝厂为例,详细说明了物质减量化原理在资源价值流计算中的应用过程。     

Evidence from China on the value relevance of operating income vs. below-the-line items

This study investigates the value relevance of operating income vs. below-the-line items in the Chinese stock market. The motivations for this study are twofold. First, there is a need for empirical evidence of the value relevance of earnings components given that previous findings of value relevance in China at the aggregate level have often been questioned in the literature. Second, the reporting environment for earnings components in China provides an interesting opportunity to present additional evidence on the pricing of persistent vs. less persistent earnings. Chinese GAAP is more specific in defining the scope and specifying the format of reporting earnings components with different levels of persistence. In addition, differing from the U.S. evidence in the extant literature, below-the-line items in China is overwhelmingly income-increasing and frequently account for a large percentage of a firm's reported net income. By linking valuation analysis with earnings time-series properties, we present additional evidence to support value relevance in China: An earnings component is impounded in stock prices as long as it is persistent and nonpersistent below-the-line items are value irrelevant. However, the time-series properties of earnings components are not fully priced by the market. The earnings-response coefficients are larger for below-the-line items than for operating income, although below-the-line items are less persistent and have lower predictive power. In discussing this pricing anomaly, we identify some unique institutional factors that may be responsible for the results.
