中国制造业上市公司多元化经营与企业价值研究 总被引:1,自引:0,他引:1
上市公司多元化溢价或折价问题一直是学术界研究的焦点,本文选取上市的704家制造企业作为样本空间对这一问题进行分析,发现定性上可以认为多元化有利于企业价值的提升,但是在定量上来看这种提升无法通过显著性检验,而且不同的衡量多元化的指标与不同的衡量企业价值的指标之间得出的结论很可能不同,因此如何选取相应的衡量指标应该是相关研究的首要问题。 相似文献

Automatic order matching systems have emerged as an electronic alternative to traditional markets. In current automatic order matching systems, price and quantity are the only product dimensions used for the order matching. However, a single-commodity market is made up of many heterogeneous goods which are close to each other but different in qualities and delivery conditions. Price and quantity are important but represent only parts of product attributes that commodity traders want to take into account. This study aims to extend current automatic order matching systems by diversifying product dimensions. An intelligent order matching system not only maximizes the total transaction volume based on the price and quantity but also satisfies traders' qualitative preferences over attributes other than price and quantity. The intelligent order matching mechanism combines an economic model with a preference model to incorporate both quantitative and qualitative utility of market participants. Constraint logic programming is investigated as a new information technology to structure and implement the intelligent order matching system. 相似文献

This research examines whether investments in advanced manufacturing technologies (AMTs) such as flexible manufacturing systems (FMS), computer aided design (CAD), computer aided manufacturing (CAM), robotics, etc., are more likely to lead to improved performance if they are supported by improvements in the manufacturing infrastructure of the company. This question is evaluated using data gathered from 202 manufacturing plants chosen from industries generally considered to have relatively high investments in technology.Multiple item scales are developed and adapted from sources in the literature to measure investments in technology, infrastructure, and the performance of the plant. Evidence supporting the reliability and validity of these scales is provided. Hierarchical regression is used to analyze the relationship between technology, infrastructure, and performance. The results suggest that there is an important interaction between the adoption of advanced manufacturing technologies and investments in infrastructure. Firms that invest in both AMTs and infrastructure perform better than firms which only invest in one or the other. Separate analyses on sub-samples of firms with the highest and lowest investments in AMTs show that infrastructural investments have a stronger relationship with performance in the high investment group. Thus, the data indicate that infrastructural investments provide a key to unlocking the potential of advanced manufacturing technologies. 相似文献

This study examines whether independent directors who possess financial expertise and are independent from the CEO (i.e., non-co-opted) are associated with improved outcomes for industry superannuation funds. Our results highlight that independence alone is insufficient to improve fund outcomes. Instead, we find that only non-co-opted independent directors benefit fund members in terms of higher performance and lower fees. Moreover, we find that independent directors' financial expertise is not associated with fund performance and fees. Our study has implications for regulators and superannuation funds who are currently debating the need for one-third independent directors on the board of Australian superannuation funds. 相似文献
