Do ongoing networks block out new friends? Reconciling the embeddedness constraint dilemma on new alliance partner addition

Research Summary: This study addresses a theoretical dilemma regarding how alliance network constraint (reflected by network cohesion) affects a firm’s alliance formation with new partners. Using a network pluralism approach, we separate a firm’s ego alliance network into two activity‐based networks—an exploratory network and an exploitative network—based on the primary value chain activity involved in each alliance. We argue that the cohesion of exploratory or exploitative networks has an inverted U‐shaped effect on the addition of new partners in the same activity‐based network, and a positive effect on the addition of new partners in the other network. Results based on data from the biotechnology industry largely support our predictions with one exception. Our study contributes to both scholarly understanding of network embeddedness and alliance practice. Managerial Summary: The structure of firms’ ongoing alliance networks may have paradoxical implications for their efforts to search for and form alliance with new partners. That is, when a firm’s alliance partners are tightly connected with each other, the cohesive network tends to both encourage and impede the focal firm to add new partners. We resolve this dilemma by showing that when a firm is deeply entrenched in a cohesive alliance network conducting a certain type of activities (e.g., R&D activities), it may not easily add new R&D alliance partners. However, it may still be able to escape from the cohesive R&D alliance network by seeking new partners conducting other activities (e.g., manufacturing activities).     

Does proximity matter in international bond underwriting?

In this study, we analyze a sample of 3982 international bond issues from 31 countries to examine the impact of geographic proximity on the selection of lead underwriter in the international bond market. We find that proximate banks are more likely to lead underwrite risky bonds and non-rated bonds. On average, the total issue cost is lower if the lead underwriter is a proximate bank. The overall results suggest that geographically proximate banks have better access to private information about issuing companies. We also find that the cost reduction effect of proximate underwriting only appears in developed markets. In addition, this cost reduction effect is relatively weak in countries with a legal system that provides good investor protection.     

河南省区域经济差异的实证分析

利用SPSS19.0统计分析软件,采用2008年河南省经济社会发展的统计数据,构建区域经济评价指标体系,通过因子分析法对河南省18个省辖市的区域经济差异状况进行实证分析,结果表明河南省区域经济发展存在着较大差异。缩小差异,促进河南区域经济协调发展应加大对落后地区的支持力度,增加落后地区的投入;强化点轴扩散效应,优化空间开发结构;调整产业结构,促进区域间产业的合理分工与协作。

Beyond symbolic and substantive: Strategic disclosure of corporate environmental information in China

Under increasing regulatory pressure to disclose environmental impacts, corporate environmental information disclosure (EID) is becoming more prevalent. However, the motives for EID and disclosure approaches (i.e., symbolic or substantive) remain controversial. Using a sample of data for 742 listed manufacturing firms in China across 3 years, we provide evidence to show that the level of EID is significantly positively associated with a firm's advertising intensity and that firms in moderately competitive industries have a higher propensity for adopting an EID‐based differentiated strategy than firms in stronger or weaker competitive industries. We also find that firms that are more sensitive to environmental issues strategically understate their environmental impact when directly facing consumers. Our results suggest that the implementation of corporate EID is strategic and that firms have strong market motives, even under regulatory pressure to demonstrate legitimacy. We discuss this study's contributions to research on EID theory and implications for strategic EID management.     

领导力在项目组合管理中的影响研究

项目组合是连接战略和项目的桥梁。区别于以往有关项目管理中领导力的研究,针对高管和项目经理两种层次的领导角色,界定了领导力的内涵,从战略视角出发构建了领导力对项目组合绩效的影响作用模型,并运用偏最小二乘法和实证方法对理论模型进行检验。研究结果表明,高管及项目经理的领导力均对项目绩效、组合绩效有积极的影响,但项目绩效对组合绩效的作用并不显著。结论强化了领导力在项目组合管理中的关键作用,为研究组合绩效的提升机制提供了新的思路和方法。
