我国粮食对外贸易中的一个“悖论”及其成因探析

按照比较优势理论,我国应净进口粮食这一土地密集型产品。但本文在实证分析后却发现,1997年以来我国已经成为粮食产品的净出口国。粮食产品较低的“可贸易度”制约了市场机制及比较优势作用的发挥。但从中长期来看,粮食产品的“可贸易度”会呈上升态势,发挥国内外“两个市场”的作用对增强我国粮食安全保障具有重要意义。     

Validating new product creativity in the eastern context of Malaysia

This paper examines the etic vs. emic nature of the new product creativity (NPC) construct often used in the strategic marketing and management literatures. The current study compares the NPC measure developed by Im and Workman (2004) in the West in an Eastern context by utilizing data from 172 Malaysian companies. The results show that NPC, which is the combination of new product (NP) novelty and NP meaningfulness, has a different connotation in Malaysia. The findings demonstrate that from the novelty perspective NPC is an emic phenomenon. After the construct validation process, the Western claim that NPC is a seed of firm performance is tested. The results verify NPC's relationship with NP performance as a source of competitive advantage for Malaysian firms and thus suggest that this relationship is etic in nature. These findings have significant implications for firms' global innovation strategies.

Beyond convenience: the future for independent food and grocery retailers in the UK

The UK's independent food and grocery retail sector's competitive advantage of 'convenience' has been eroded in recent years as major retailers increase opening hours and develop their own convenience trading formats. As a result, large numbers of independent retailers are closing. A UK-wide survey was undertaken to identify other sources of competitive advantages, and the changes needed to stop or reverse the decline in this sector. Exploratory semi-structured interviews led to the development of a questionnaire on six major issues affecting the sector. 'Snowball' sampling, using industry partners, provided 142 respondents. The provision of a 'social shopping experience' emerged as a key competitive advantage that could be developed. Improving vertical and horizontal trading alliances, and the wider use of information technology, provided other options.

Second‐Mover Advantages with Asymmetric Costs and Information Updates: A Product Life Cycle Perspective

Two firms with asymmetric costs engage in a Stackelberg game under multiple levels of uncertainty with information updating. A product life cycle perspective is employed to reveal when and why a second‐mover may have an advantage. At early stages in the product life cycle, when uncertainty is the dominating factor, the impact of uncertainty may be either positive or negative. As a result, the Stackelberg leader faces the possibility of either overshooting or losing its market leadership position to the second‐mover. In later market stages, when cost is more important, a process‐innovating second‐mover may accrue higher profits. Copyright © 2011 John Wiley & Sons, Ltd.

人民币汇率升值预期对我国国内生产成本的影响

改革开放以来,我国凭借国内生产的成本优势在国际贸易中获取了大量利益。出口刺激了经济的快速增长,然而持续顺差带来的本币升值问题却成为我国经济发展中的两难。虽然汇率升值可能造成出口部门竞争力下降,但是,理论上讲,汇率的升值也能够缓解国内通货膨胀的压力,并且能够降低进口原材料价格,从而降低国内的生产成本。然而,自汇改以来,人民币的升值并没有减缓通胀压力,相反的,升值一直伴随着物价的上涨,于此同时,人民币汇率、国内资产价格和物价之间的联动越来越明显。本文从人民币汇率预期、资产价格和物价的关系入手,研究人民币汇率升值预期对我国国内生产成本的影响。结果表明,人民币升值预期会导致我国国内生产成本的上涨,即成本优势的丧失。
