Centralization of intragroup equity ties and performance of business group affiliates

Research summary : Although prior research has suggested that equity ties are important for business groups, less attention has been paid to the specific mechanisms through which equity ties create value. We develop a framework that specifies how centralization of intragroup equity ties affects the performance of group affiliates. We use the exogenous shock of the 2008 financial crisis and a difference‐in‐differences analysis of 51,730 observations of business group affiliates in Taiwan to show that centralization of equity ties enhances affiliate performance, but such effects weaken when the environment becomes turbulent. Moreover, we find that listed affiliates obtain fewer benefits from centralization than unlisted affiliates. Overall, our study deepens scholarly understanding of not only how groups create value, but also how value is differentially appropriated among affiliates. Managerial summary : Our research speaks directly to owner‐managers of business groups with respect to creating an optimal equity network structure that binds the affiliated firms of the group. Our findings suggest to managers that the overall structure of equity ties in a business group has major implications for the performance of the affiliate firms of the group, and the network structure within the group should be designed deliberately and thoughtfully on an on‐going basis. In particular, control through centralized equity ties is performance‐enhancing in normal periods, but such control may be counterproductive as turbulence increases in business environments, or as the number of listed group firms increases. Hence, owner‐managers may consider optimizing the network structure by lowering the degree of centralized equity ties under such circumstances, or at a minimum, lowering centralized control.

MANET路由协议在RPGM模型下的性能分析

本文首先对MANET网络中三种典型的路由协议DSDV、DSR和AOVD进行简单介绍,然后利用网络仿真工具NS2对MANET网络中这三种路由协议在RPGM群组移动模型下和不同移动节点数下的平均吞吐量、平均端到端时延、分组投递率和路由开销的仿真结果进行分析。     

客户关系与企业研发投资决策

从企业商业关系网络视角, 探讨客户关系对企业研发投资强度的影响. 研究发现, 客户集中度与企业研发投资强度呈现倒 "U" 型关系. 进一步从企业的集团属性和地区金融发展水平研究发现, 在非集团企业样本中, 客户集中度与企业研发投资的倒"U" 型关系依然存在, 而在集团企业样本中, 客户集中度与企业研发投资则显著负相关;同样地, 在地区金融发展水平较高样本中, 客户集中度与企业研发投资的倒 "U" 型关系依然存在, 而在地区金融发展水平较低样本中, 客户集中度与企业研发投资则显著负相关. 研究表明企业的研发投资作为一种专用性资产投入, 既具有在客户集中度方面的信号传递价值, 还会在不同的融资约束情景下体现不同的投入强度, 彰显其显著的环境调节功能, 有助于企业多角度考量研发投资决策.     

群体纠纷解决机制的最新发展研究

随着世界经济一体化的发展,群体纠纷日益增多。世界各国都在努力寻找解决它的办法,我国也不例外。要解决好群体纠纷,必须明确其类型,以做到具体情况具体对待。同时,我们也要了解世界各国典型的群体纠纷解决类型,并对他们进行比较,只有这样我们才能更好地知道哪种方法适合我们国家。最后,要想更好地解决群体纠纷,就要明确群体诉讼在我国的事实与法律现状以及存在的问题,以求努力解决之。     

Group size and the (in)efficiency of pure public good provision

Are larger groups better at cooperation than smaller groups? This paper investigates, under controlled conditions, the presence and direction of a possible group size effect in pure public good provision by large heterogeneous groups. Employing subjects drawn from the general population and introducing Internet-based procedures to study this question, we collected experimental evidence from 1110 subjects playing a linear public goods game in groups of 10, 40, and 100 members. We find a positive and significant group size effect: Increasing group size by a factor of 10 (4) increased efficiency by 10 (6) percent. The effect arose at the intensive margin and with repetition. Those who contributed contributed more in larger groups. Larger and smaller groups had similar initial contribution levels, but cooperation rates declined more slowly in the larger groups. Free-riding was invariant to group size, despite subjects׳ persistent beliefs of a negative group size effect at the extensive margin. Further econometric examination of the data supports these findings and provides starting points for future theoretical and experimental research on the group size effect.     

天祝县民族地区特色农作物比较优势实证分析

文章采用规模比较优势指数、单产比较优势指数以及综合比较优势指数等方法,对天祝县2003~2012年种植面积较大且地域特色明显的3种主要农作物比较优势进行了横向和纵向比较,并与市内其余县域进行了差异比较分析,以期掌握天祝县主要农作物比较优势状况以及发展变化趋势。结果表明:天祝县马铃薯和油菜具有明显的比较优势,且优势十分明显,可以大力发展;蔬菜作为天祝县一个具有后发优势的产业,规模比较优势明显,单产比较优势和综合比较优势接近于1,具有潜在的发展潜力。建议天祝县特色农作物的发展,要紧紧抓住国家支持藏区建设和建立丝绸之路新经济带的历史机遇,抓住天祝县被列为全国北方油菜优势区和西北马铃薯优势产区的有力契机,走稳定规模优势、扩大产量优势、强化产品质量的良性循环发展之路。同时,要根据天祝县优势农作物产区属于复合型区域的特点,协调各种优势作物的种植规模,形成资源和要素配置合理的配置,在产业发展中要充分发挥高原气候资源优势,全面提高优势农作物的生产效率和产品质量,以实现民族地区特色农业产业健康可持续发展。
