一类含四个未知函数的方程的非平凡解的存在性的研究

本文利用亚纯函数值分布论的思想方法,对函数方程f117(z)+f127(z)+f317(z)+f147(z)=z非平凡解的状况进行研究,得到如下结果:函数方程f117(z)+f217(z)+f317(z)+f417(z)=z不存在级小于117的非常数亚纯函数解。

Value Orientations, Income and Displacement Effects, and Voluntary Contributions

Identifying the value orientations of subjects participating in market or non-market decisions by having them participate in a ring game may be helpful in understanding the behaviour of these subjects. This experiment presents the results of changes in the centre and the radius of a value orientations ring in an attempt to discover if the measured value orientations exhibit income or displacement effects. Neither significant income effects nor displacement effects are identified. An external validity check with a voluntary contribution game provides evidence that value orientations from rings centred around the origin of the decision-space explain significant portions of voluntary contributions while value orientations from displaced rings do not.     

Strategies of Korean firms in china's high‐tech market: Striving for a new and sustainable business model

China has become a strategically important market for Korean companies. While cooperating with China is obviously important for their success and survival, a more difficult question lies in finding a new and sustainable business model applicable to China. This paper studies the current challenges and strategies of Korean Small and Medium‐sized Enterprises (SMEs) in the high‐tech market such as the mobile handset and online game industries that are trying to extend their business to China. It focuses on the issue that Korean firms face in order to find a way to survive and integrate with a rising China. By conducting an in‐depth firm level analysis, it examines their successes and failures in terms of what parts of the value chain they specialize in and how they establish a division of labor with China.     

AN ANALYSIS OF SUPPLY CHAIN COLLABORATIONS AND THEIR EFFECT ON PERFORMANCE OUTCOMES

This research examined how operational outcomes, relational outcomes and business performance are affected by a collaboration project between buyers and suppliers in a supply chain. It is hypothesized that interdependence of knowledge and process, supply chain partner insight, and the level of collaboration between the firms affect the outcomes of a collaboration project. Survey data from buyers and suppliers from a wide range of industries and organizations were used in this analysis. Among these participants, higher levels of collaboration led to improvements in operational and relational outcomes, which together led to improvements in asset utilization, competitive position, organizational performance, and profitability.     

全球价值链与国内价值链——基于投入产出表的新方法

价值链作为组织和协调经济活动的微观机制,已使经济全球化和增长模式发生了深刻的变化。本文利用来自投入产出表的新方法,测度了广东省和江苏省全球价值链和国内价值链的水平。结果表明,粤苏两省切入全球价值链的倾向高于切入国内价值链的倾向,而对其它省份关联效应较大的行业基本上是中间品行业,且具有自然资源密集的特征。全球价值链与国内价值链之间的互动关系,则关系到我国产业升级的前景和区域经济协调发展的基础。     

Which Way is “Up” in Upgrading? Trajectories of Change in the Value Chain for South African Wine

Global Value Chain (GVC) analysis uses the concept of upgrading to highlight paths for developing country firms to “move up the value chain,” usually through the lenses of four categories—product, process, functional, and inter-sectoral upgrading. The implicit normative expectation is that these firms move toward producing higher value-added products and/or take on more sophisticated functions along a value chain. In this article, upgrading is approached more broadly as “reaching a better deal,” including a balance between rewards and risk. The case study of South African wine shows that better product quality, improved processes, and some functional upgrading have co-existed with processes of “downgrading,” higher risks, and limited rewards, especially in traditional export markets. A reflection on further conceptual development and directions for empirical research is also provided.
