Research on Sustained Development of Supply Network Based on HITS Conception

21st century is a new century with the conception of ＂centralized on customers＂ instead of ＂centralized on products＂. A key feature of nowadays business is the idea that it is supply chains＇ competition, not companies. The present researches to supply chain strategy most concentrated on the operation level. However, the support level which consists of technology, institution, human resource and surroundings is also a factor of cardinal significance to impact the implement of supply strategy. This paper does further research on HITS （Human resource, Institution, Technology and Surroundings） factors to support the supply network sustained development.     

服务外包与产业链长度：来自中国的经验证据*

本文参考Antrs et al（2012）方法，利用中国1997年、2002年、2007年、2012年和2017年投入产出表测度30个省份17个细分行业的产业链长度，并在此基础上分析服务外包对延伸产业链长度的作用。实证结果表明：第一，从整体上看，服务外包对我国产业链长度攀升具有显著促进作用，服务外包每提高10%，可以促进我国产业链长度提升062%。第二，从细分类型的服务外包看，交通仓储外包对产业链长度延伸的促进作用最大。第三，分地区研究发现，服务外包对中部地区产业链长度提升最大，其次是西部地区，东部地区最小。第四，分行业后发现，服务外包对制造业和服务业产业链长度均有提升作用，但是对服务业促进作用是制造业的近2.7倍。     

RECENT PROGRESS IN APPLIED BAYESIAN ECONOMETRICS

Abstract. Bayesian methods are widely used by theoretical econometricians and statisticians but have not won widespread acceptance from applied researchers. After briefly describing the basic of the Bayesian approach, we discuss several issues relating to the empirical application of Bayesian methods. The existing Bayesian empirical literature is also partially summarized. The remainder of the paper offers a non-technical survey of some recent computational advances in Bayesian econometrics. The overall goal is to persuade economists that Bayesian methods are both computationally feasible and easy to implement in empirical research.

Corporate Social Responsibility in Supply Chains of Global Brands: A Boundaryless Responsibility? <Emphasis Type="Italic">Clarifications,Exceptions and Implications</Emphasis>

Corporate social responsibility (CSR) is increasingly becoming a popular business concept in developed economies. As typical of other business concepts, it is on its way to globalization through practices and structures of the globalized capitalist world order, typified in Multinational Corporations (MNCs). However, CSR often sits uncomfortably in this capitalist world order, as MNCs are often challenged by the global reach of their supply chains and the possible irresponsible practices inherent along these chains. The possibility of irresponsible practices puts global firms under pressure to protect their brands even if it means assuming responsibilities for the practices of their suppliers. Pressure groups understand this burden on firms and try to take advantage of the situation. This article seeks to challenge the often taken-for-granted-assumption that firms should be accountable for the practices of their suppliers by espousing the moral (and sometimes legal) underpinnings of the concept of responsibility. Except where corporate control and or corporate grouping exist, it identifies the use of power as a critical factor to be considered in allocating responsibility in firm–supplier relationship; and suggests that the more powerful in this relationship has a responsibility to exert some moral influence on the weaker party. The article highlights the use of code of conducts, corporate culture, anti-pressure group campaigns, personnel training and value reorientation as possible sources of wielding positive moral influence along supply chains.

Adjustable-rate mortgages,household mobility,and homeownership: A simulation study

A semi-Markov model is used to evaluate the effects of adjustable-rate mortgages on housing tenure decisions of recent movers and steady-state homeownership rates. Simulations were undertaken based on household data from the Panel Study of Income Dynamics together with information on FRM-ARM rate spreads and Treasury yield curves. Results suggest that under most interest rate patterns that prevailed in the 1980s, ARMS had little effect on the relative cost of owning to renting and, as a result, had little effect on mover tenure choice and home sales. Moreover, despite some minor projected increase in the percentage of movers that choose to own when ARMs are available, ARM effects on steady-state owner-occupancy rates appear to be largely mitigated by an ARM-induced tilt toward a relatively more mobile steady-state pool of owner-occupiers.     

Performance of cumulative sum schemes for monitoring low count-level processes

In many instances attributes data must be used to monitor a manufacturing (or other) process that, in normal conditions, should operate at very low count levels for defects. Lucas (1989) has directed attention to this problem, and has investigated a new control scheme for low count-level processes. An alternative scheme is proposed, based on a Cumulative Sum (CUSUM) of the number (termed Run-Length) of successive samples having zero count-levels between samples having at least one count. Using the criterion of Average Run Length (the average number of samples until a signal is generated) comparisons of the Lucas scheme and the Run-Length CUSUM scheme indicate that ARL values for the Run-Length CUSUM can be up to 50% lower.     

顾客价值链探析

顾客不仅仅是“经济人”、“消费人”,更是“生活人”,消费行为是其生活活动中的一个环节。研究顾客需求、顾客价值,制定有效的营销战略应该从顾客生活角度出发。生活价值追求形成顾客生活价值链;往往某一生活活动由若干种消费活动组成,各相关消费形成顾客追求生活价值的一个“组合消费价值链”;而某一消费行为是其中一个基本组成单元,单项消费的各有关环节组成“单项消费价值链”,与其他相关生活、消费行为紧密关联。企业的产品经营可以通过顾客价值链营销,提升顾客有关生活价值体系的整体价值水平,来营造良好的产品生态环境,提高顾客满意度和产品营销水平。
