在日中国留学生异文化适应的社会人类学研究

本文据笔者在日本的实地调查,从社会人类学的视角观察一组来自中国不同地方的留学生的日语基础、学历与毕业后去向的相互关系,用芝加哥学派异文化适应中的"边缘人(marginal man)"概念分析3个不同类型的个案,探究其中因异文化不适应而引发的现实问题,其中除了个人的心理素质、日语基础等个人原因外,日本与中国在文化传统、心理模式的差异是主要原因之一,而这个根本性问题还没有引起日本教育界的普遍重视.所以,虽然日本学校有优良的学习环境,但相当数量的留学生毕业后选择了回国或去第三国.留学生的异文化适应问题的解决,需要政府、学校、社会诸方面的共同努力.本文提出解决此问题的相关建议,论述研究此问题对中国解决外国留学生的异文化适应问题的借鉴意义.     

Competitive and Collaborative Quality and Warranty Management in Supply Chains

Product quality and product warranty coverage are two important and closely related operational decisions. A longer warranty protection period can boost sales, but it may also result in dramatically increased warranty cost, if product quality is poor. To investigate how these two decisions interact with each other and influence supply chain performance, we develop a single‐period model with a supplier that provides a product to an original equipment manufacturer, which in turn sells it to customers. Customer demand is random and affected by the length of the product warranty period. Warranty costs are incurred by both the supplier and the manufacturer. We analyze two different scenarios based on which party sets the warranty period: manufacturer warranty and supplier warranty. Product quality is controlled by the supplier, and the manufacturer determines the ordering quantity. We analyze these decentralized systems and provide the structural properties of the equilibrium strategies. We also compare the results of centralized and decentralized systems and identify the conditions under which one system provides a longer warranty and better product quality than the other. Our numerical study further shows that, in decentralized settings, when the warranty period is determined by the firm sharing the larger proportion of total warranty costs, the supply chain can achieve greater system‐wide profit. Both parties can therefore benefit from properly delegating the warranty decision and sharing the resulting additional profit. We further design a supplier‐development and buy‐back contract for coordinating decentralized supply chains. Several extensions are also discussed.     

基于国外经验的农商行公司治理内外部机制完善

当前,全国农村信用合作社大多已经改制为农村商业银行,改制后其如何服务经济发展仍需持续探索.现实问题在于,乡村振兴战略下的涉农金融供给疲软,"三农"金融需求未得到充分满足.合作金融改革的原因众多,但长期主体地位及法律地位不明确、权利义务责任不对等是主要原因.改制后的农村商业银行应聚焦主业、回归本源,通过完善董事会和监事会制度、加快出台农村商业银行法、健全支农配套体系、差别化监管、落实股东大会法定职权、完善对董事、监事、高级管理人员的任用及议事规定、制定董事、监事、高级管理人员激励约束机制等方式加强公司治理,尤其注重发挥法律的引领及固化作用,努力实现农村商业银行商业盈利性及支农政策性的共生与共赢.     

低碳背景下制造业商业模式创新策略研究——以卡特彼勒公司为例

低碳经济要求制造企业克服经济增长与环境超载之间的矛盾,但在传统商业模式下往往无法达到"双赢"。本文以战略分析和创新理论为依据,论述了低碳约束下制造业商业模式创新的驱动因素、作用机理以及创新要素,设计了理论框架,在此基础上探讨了低碳背景下商业模式创新的难点,提出了三方面的创新策略,并通过对卡特彼勒的案例分析验证了上述策略。结果表明:制造业可以通过改造价值链以建立逆向供应链、增强服务以及构建低碳技术壁垒的方式实现商业模式创新。研究在一定程度上丰富了相关学术成果,为我国现代制造业顺应低碳经济需求提供了具有可操作性的指导。     

The Effects of Competitive Environment on Supply Chain Information Sharing and Performance: An Empirical Study in China

Information sharing in supply chains has become an important topic over the past decade. This study uses data from 617 Chinese manufacturing firms to investigate the relationships among competitive environments, supply chain information sharing (SCIS), and supply chain performance. The results of structural equation modeling analysis show that (i) international competition is positively related to all three types of SCIS whereas local competition is not significantly related to any of the three types, (ii) internal information sharing is positively related to external information sharing with suppliers and customers, and (iii) internal information sharing and information sharing with customers are positively related to superior supply chain performance, whereas supplier information sharing is not significantly related to performance. The findings enhance our understanding of the relationships among competitive environment, SCIS, and supply chain performance in Chinese manufacturing settings.     

Quality Risk Ratings in Global Supply Chains

Extended enterprises face many challenges in managing the product quality of their suppliers. Consequently characterizing the quality risk posed by value‐chain partners has become increasingly important. There have been several recent efforts to develop frameworks for rating the quality risk posed by suppliers. We develop an analytical model to examine the impact of such quality ratings on suppliers, manufacturers, and social welfare. While it might seem that quality ratings would benefit high‐quality suppliers and hurt low‐quality suppliers, we show that this is not always the case. We find that such quality ratings can hurt both types of suppliers or benefit both, depending on the market conditions. We also find that quality ratings do not always benefit the most demanding manufacturers who desire high‐quality suppliers. Finally, we find that social welfare is not always improved by risk ratings. These results suggest that public policy initiatives addressing risk ratings must be carefully considered.     

中国城市经济效率测度研究

文章选取固定资产投资总额、劳动力作为投入变量,地区生产总值、地方财政预算内收入、职工工资总额作为产出变量,运用DEA分析法对中国城市经济效率进行了研究。研究发现,城市的纯技术效率、规模效率与城市所处的地理位置无关。城市规模效率与城市人口呈正相关关系,增加城市规模能够提高城市效率。中国近年来技术进步和技术效率呈轻微下降趋势,城市规模效率呈低速增长。技术进步和全要素生产率较高的城市以东部地区城市为主。在城市经济发展过程中应注意优化资源配置,加快技术进步。     

优化知情选择服务提升知情选择效益

中国自20世纪90年代中期开展避孕方法知情选择以来,知情选择面迅速扩大,计划生育面貌为之一新.但实际考察表明,各地开展知情选择的收效有很大差异,究其原因,主要是当知情选择普及到一定程度后,能否把握好知情选择服务质量成为提高效益的关键.浙江省从2001年起下大力量抓知情选择服务质量,收到明显效益,体现了计划生育以人为本、来自于民和服务于民的宗旨.他们提高知情选择效益的一套做法,有一定参考价值.
