The Importance of Social Capital to the Management of Multinational Enterprises: Relational Networks Among Asian and Western Firms

Social capital is an important concept for multinational firms. Firms operating in global markets rarely have adequate resources to compete effectively in global markets; they access the needed resources through formal and informal relationships with other firms. The cultures in Asian countries have emphasized relationships much more strongly than Western firms. Thus, relational capital, based on guanxi (China), kankei (Japan) and inmak (Korea), provides the framework for business dealings in many Asian countries. As a result, the social capital of many Asian firms gives them a potential competitive advantage in global markets. Western firms must develop social capital and learn to manage relational networks to gain and sustain a competitive advantage in global markets. Western firms can learn how to develop and manage social capital from Asian firms. Alternatively, social capital has some disadvantages. Firms are limited by their networks and thus experience opportunity costs and path dependence. Additionally, while Asian firms often have strong network ties in their domestic markets, they have to develop many more ties globally to operate effectively in global markets. As a result, the development and management of social capital has become of critical importance for competitive advantage in global markets.     

区域技术创新能力影响因素的实证分析——基于全国30个省市区的面板数据

区域技术创新能力的影响因素是理论界尚未系统深入探讨的问题。本文在阐明技术创新机理的基础上,运用经过改进的格瑞里茨和杰菲的知识生产函数模型,对2005—2007年我国30个省市区三大技术创新主体投入产出面板数据进行技术创新能力影响因素的实证分析,并把市场化因素首次设为虚拟变量引入模型考察其作用。分析结果表明,中国区域技术创新二次产出存在多样化差异,R&D在技术创新主体之间和内部的配置,以及创新主体内外制度性因素对技术创新的绩效有重要影响。因此,提高区域技术创新能力需要优化R&D配置和进行技术创新主体的体制机制创新。     

Economic design of an chart for short-run production

The aim of this paper is to present an economical design of an X chart for a short-run production. The process mean starts equal to μ₀ (in-control, State I) and in a random time it shifts to μ₁>μ₀ (out-of-control, State II). The monitoring procedure consists of inspecting a single item at every m produced ones. If the measurement of the quality characteristic does not meet the control limits, the process is stopped, adjusted, and additional (r-1) items are inspected retrospectively. The probabilistic model was developed considering only shifts in the process mean. A direct search technique is applied to find the optimum parameters which minimizes the expected cost function. Numerical examples illustrate the proposed procedure.

‘Globesity’? The effects of globalization on obesity and caloric intake

We examine the effect of globalization, in its economic and social dimensions, on obesity and caloric intake, namely the so –called ‘globesity’ hypothesis. Our results suggest a robust association between globalization and both obesity and caloric intake. A one standard deviation increase in globalization is associated with a 23.8 percent increase in obese population and a 4.3 percent rise in calorie intake. The effect remains statistically significant even after using an instrumental variable strategy to correct for some possible reverse causality and ommited variable bias, a lagged structure, and corrections for panel standard errors. However, we find that the primary driver (of the ‘globesity’ phenomenon) is the ‘social’ rather than the ‘economic’ dimension of globalization, and specifically the effect of changes in ‘information flows’ and ‘social proximity’ on obesity. A one standard deviation increase in social globalization increased the percentage of obese population by 13.7 percent.     

创新团队公平感知与知识共享行为关系研究——以成员信任为中介变量

创新团队组织形式的蓬勃发展使得团队成员的绩效激励方式成为众多管理者的研究课题。团队中掌握独特隐性知识的成员往往不愿意共享自身的有利于团队的创新知识,从而给团队的发展带来困难。如何针对这类员工做出有利于团队整体绩效提升的激励活动,是创新团队管理者和所有创新团队工作模式研究者的共同目标。通过数据模型的回归,得出如下结论:创新团队的成员公平感知与成员知识共享行为正向相关,成员对互动公平的感知对知识共享行为的影响最为显著。验证了创新团队成员信任在成员公平感知与知识共享行为之间的中介效用。     

Fuzzy Pair-wise Dominance and Implications for Technical Efficiency Performance Assessment

Classically, the concept of efficiency measurement is based on the definition of a frontier that envelops the observed production plans. The efficiency score itself is based on the distance of an observed production plan from this frontier. The frontier along with the required technological assumptions (such as convexity) needed for its definition may be replaced with the concept of pair-wise dominance. This concept leads to a classification scheme for all production plans instead of a ranking based on efficiency scores. Also, the traditional assumption of deterministic or crisp production plans may be substituted with the weaker assumption of fuzzy production plans as proposed by fuzzy set theory. This paper merges these two concepts and defines a new classification scheme based on fuzzy dominance.     

企业生产物流中物料搬运方式的优化

企业生产物流中物料的搬运方式一般由所搬运的物料的功能、性质、搬运量等进行选择，仅局限于定性分析。通过建立数学模型，对企业生产物流搬运方式进行定量优化，并通过实例，说明对生产物流搬运方式进行量化分析是可行的。
