上市公司年报供应链信息披露现状分析

本文认为,供应链信息是对公司进行分析评价的重要依据,而现行体制下的年报规范并不要求直接披露供应链信息,而是通过一些间接指标和情况来反映公司的供应链情况。文章指出,通过供应链特征词词频分析可了解公司对供应链管理的关注程度;通过基于主要交易额的聚类分析可认识上市公司供应链集成度的总体水平和具体公司的供应链集成度。这两种聚类分析原理和方法不同,但结果基本一致,结论可相互印证。总体看来,我国上市公司对供应链管理关注程度不够,综合供应链管理水平偏低;虽然供应链集成度总体水平较低,但在部分供应链环节上,相当多的公司已经具有了较高的供应链集成度;公司年报对供应链信息关注和披露的程度有逐年上升的趋势,少数企业已开始有意识地从供应链视角披露自身重要经营事项。     

供应链集成研究

企业竞争地位、供应链集中度与权益资本成本

本文以2004-2014年沪深A股非金融行业上市公司为研究样本,结合企业竞争地位,系统分析并验证供应链集中度影响权益资本成本的作用机理及可能的传导路径。研究结果发现:供应链集中度越高,企业权益资本成本随之提升;经营风险是供应链集中度影响权益资本成本的一个中介路径,即企业较高的供应链集中度会加剧其面临的经营风险进而导致权益资本成本增加。较高的企业竞争地位能够弱化供应链集中度对权益资本成本的负面影响,且企业竞争地位是通过缓解企业的经营风险这条路径影响了二者之间的关系,即较高的企业竞争地位因其具有较强的抵御风险能力从而缓解了供应链集中度引发的经营风险,继而对供应链集中度与企业权益资本成本之间的正相关关系产生弱化作用。

中国铜行业上市公司效率评价分析

随着我国经济的发展,铜业企业发展迅速,但是我国铜资源不足和日益增长的铜需求之间的矛盾日益突出,因此对于铜类企业的效率情况分析日益重要。从我国铜类上市公司着手,将铜类上市公司按照产业链划分,通过数据包络模型对铜类企业效率进行测算。研究发现,处于生产链上游的铜类上市公司其效率较高,而中下游铜类上市公司效率较低,存在效率不平衡现象。因此需要政府对中下游铜类公司进行有效的引导与支持,从而提高整体的铜类公司效率。

Cross-Sector Competition in Telecommunications

Cross-sector competition in the information and communications technology sectors (ICT sectors) constitutes a key strategic challenge for telecommunications companies. Due to increasing convergence, value creation is resulting in a greater degree of interaction. The diversification potential of telecommunications businesses is therefore changing with respect to associated ICT sectors, such as hardware, software and media. The article analyses cross-sector competition in the telecommunications industry on the basis of the diversification activities of ICT companies. A concentration of competitive interdependence in the ICT sectors is demonstrated using a cluster analysis of 34,142 companies. The cross-sector activities of telecommunications companies are investigated using contingency and dependency analyses, and the diversification-related competition in the telecommunications sector is also analysed. With regard to the telecommunications sector, particularly high level cross-sector competition with the media industry is identified, as well as strong diversification activities in the software sector. The results are used to derive the potentials and risks that have a significant bearing on the structure of the cross-sector competitive environment of telecommunications companies.     

The internationalization journey of a high‐tech cluster

We examine the internationalization processes of a sample of photonics companies, using in‐depth interviews conducted with twenty‐two CEOs. The texts of these interviews were appraised by using content analysis, combined with a grounded theory approach. In this way, the internationalization theory was critiqued and some insights developed into the international strategy process. Some salient findings emerged, such as that cluster externalities had a positive impact on the internationalization of firms within the cluster, and the degree of strategic vulnerability that cluster firms faced from developing‐country competitors. These findings are discussed in relation to their research and managerial implications. © 2005 Wiley Periodicals, Inc.

A Hierarchical Clustering Approach Based on Three-Dimensional Gray Relational Analysis for Clustering a Large Group of Decision Makers with Double Information

Two types of information, collectively referred to as double information, are usually required in management decision-making. The first is preference information expressed in a judgment matrix. The second is reference information expressed in a multi-attribute decision matrix. In this paper, we investigate large-scale group clustering problems with double information in group decision-making. We first establish a novel three-dimensional gray correlation degree index, which integrates the alternative decision-making vector, index vector and alternative preference vector, to fully excavate the correlation between decision makers with double information. We then develop a new clustering procedure combining three-dimensional gray relational analysis and the concept of hierarchical clustering. Moreover, a model for determining clustering centers is established on the basis of the maximum gray correlation degree within each cluster and minimum gray correlation degree among clusters. A heuristic algorithm for the model to identify the core decision maker in each cluster is proposed. Finally, we illustrate the applications of the developed procedures with a practical case. The rationality of the proposed method is demonstrated by comparing results with results obtained using other methods, including the traditional gray clustering method and hierarchical clustering method with single information; i.e., preference information or reference information.     

A Simplified Approach to Teaching the Value of Multinational Diversification

The purpose of this study was to examine the degree to which a specific time-based country experience outside of the subject’s native regional cultural cluster, would be able to explain the subject’s level of cultural intelligence. Using a sample of 143 subjects, the results suggest individuals who have identified the country within which they have spent the most total time to be a non-Anglo country had developed a higher level of cultural intelligence than demographically similar U.S. citizens in the sample who spent their most significant amount of time in an Anglo cluster country. In addition, it was found that those subjects within the Anglo culture cluster group who traveled internationally but spent the greater amount of time in a foreign Anglo culture country (i.e., non-USA), did not significantly differ in three of the four cultural dimensions from those who never traveled outside of the USA. These results suggest country choice can make a difference.

Does family ownership shape performance outcomes?

This paper analyses the effect of family ownership on performance in an emerging economy. Two dimensions represent family ownership: ownership concentration and characteristics of family control (i.e. family involvement in the board of directors). The study also includes the effect of firm institutional relatedness on performance, meaning the degree of informal embeddedness or interconnectedness with dominant institutions. The empirical analysis uses a data set of publicly traded Chilean firms from 2000 and 2003. The evidence indicates that performance depends on ownership concentration and that family control and institutional relatedness also have a significant effect.
