企业能力、竞争强度与对外直接投资动机——基于重庆摩托车企业的多案例研究

本文运用多案例研究方法,选取四家重庆摩托车企业的八次对外直接投资案例,对企业能力、竞争强度如何影响企业对外直接投资动机的形成进行了探讨.研究发现,我国摩托车企业的对外直接投资动机主要表现为寻求海外市场.当企业不具备技术相关能力和市场相关能力的相对优势,面临竞争者增多、价格竞争增强的情况时,企业容易产生防御型市场寻求的对外直接投资动机,并且如果主要竞争者已在目标市场投资,更容易促发企业形成这类动机.当企业具备技术相关能力和市场相关能力的相对优势,同时又面临竞争者增多、价格竞争增强的情况时,企业容易产生进攻型市场寻求的对外直接投资动机,并且如果主要竞争者尚未在目标市场投资,更容易促发企业形成这类动机.

Family Control and Stock Market Reactions to Innovation Announcements

Although family firms are common around the world, studies on family‐controlled business are limited. Prior studies mainly focused on the influences of family ownership on overall firm performance, and the results were mixed. In this study we attempted to explore the impacts of family ownership on innovation by examining the association of family control and stock market reactions to innovation announcements. We found that firms with greater family control experienced significantly more negative stock market reactions to innovation announcements. The results further indicated that divergence of cash flow and voting rights was strongly and negatively correlated with announcement‐period abnormal returns. In addition, the findings suggested a significantly positive moderating effect of institutional ownership. The conclusions were robust under various measures of family control, and remained valid after controlling other influential factors for stock market reactions to innovation announcements.     

I warn you because I like you: Voice behavior,employee identifications,and transformational leadership

Voice behavior refers to the behavior that proactively challenges the status quo and makes constructive changes. Previous studies have explored the antecedents of employees' voice behavior, but to whom employees are likely to voice their thoughts has remained rarely examined. We propose that voice behavior is target-sensitive and that there are two types of voice behavior: speaking out (voice toward peers) and speaking up (voice toward the supervisor). Transformational leadership facilitates both speaking out and speaking up. However, it produces effects on employees via different types of employee identifications. Specifically, social identification predicts only speaking out, while personal identification predicts only speaking up. In contrast, affiliative extra-role behavior is less target-sensitive, and transformational leadership influences affiliative extra-role behavior via both social identification and personal identification. We examined our hypotheses by collecting both self-reported and coworker data from 191 Chinese employees in different organizations. Our hypotheses gained general support from the data. Implications for research and practice are discussed.     

A Risk Analysis Model in Concurrent Engineering Product Development

Concurrent engineering has been widely accepted as a viable strategy for companies to reduce time to market and achieve overall cost savings. This article analyzes various risks and challenges in product development under the concurrent engineering environment. A three‐dimensional early warning approach for product development risk management is proposed by integrating graphical evaluation and review technique (GERT) and failure modes and effects analysis (FMEA). Simulation models are created to solve our proposed concurrent engineering product development risk management model. Solutions lead to identification of key risk controlling points. This article demonstrates the value of our approach to risk analysis as a means to monitor various risks typical in the manufacturing sector. This article has three main contributions. First, we establish a conceptual framework to classify various risks in concurrent engineering (CE) product development (PD). Second, we propose use of existing quantitative approaches for PD risk analysis purposes: GERT, FMEA, and product database management (PDM). Based on quantitative tools, we create our approach for risk management of CE PD and discuss solutions of the models. Third, we demonstrate the value of applying our approach using data from a typical Chinese motor company.     

Tagged Probe Interval Graphs

A generalization of interval graph is introduced for cosmid contig mapping of DNA. A graph is a tagged probe interval graph if its vertex set can be partitioned into two subsets of probes and nonprobes, and a closed interval can be assigned to each vertex such that two vertices are adjacent if and only if at least one of them is a probe and one end of its corresponding interval is contained in the interval corresponding to the other vertex. We show that tagged probe interval graphs are weakly triangulated graphs, hence are perfect graphs. For a tagged probe interval graph with a given partition, we give a chordal completion that is consistent to any interval completions with respect to the same vertex partition.

Blocking Rumor by Cut

In this paper, a rumor blocking problem is studied with an objective function which is neither submodular or supermodular. We will prove that this problem is NP-hard and give a data-dependent approximation with sandwich method. In addition, we show that every set function has a pair of monotone nondecreasing modular functions as upper bound and lower bound, respectively.
