Asymmetric Margins in Prices and Retail Supply Chain Integration: The Spanish Vegetable Case

Several studies have observed asymmetric behavior between sale prices in the supermarket and the price paid to the farmer. This article presents the consequences derived from a simplified framework considering a scenario in which the retailer wishes to maintain balanced profits due to external pressures or because the retailers' strategy to differentiate themselves from the competition requires greater integration in the supply chain. It is shown that the price-fixing decision of the distributor may depend on the risk, measured by the relationship between demand elasticity and variable costs, as a result of uncertainty in consumer response to price variations. This risk arises from the existence of supply that is highly changeable in the short term and demand that is unpredictable.

The Role of Guanxi Networks in Vegetable Supply Chains: Empirical Evidence from P.R. China

This study attempts to empirically investigate how the concepts of relationship marketing affect market performance in Chinese vegetable sector. We interviewed 167 vegetable farmers and 84 processing and exporting companies to test our conceptual relationship model. Results demonstrate that personal relationships (called guanxi in China) significantly improve interpersonal trust and transaction-specific investments, which eventually show a significant impact on market performance. Results imply that the impact of guanxi networks differ on farmers and on companies. The study also reveals that transaction-related attributes (such as risk, channel requirements, and transaction conditions) influence trust, investment behavior, and market performance together with guanxi networks. The article ends with several managerial implications regarding the development of relationship marketing in China.     

Supermarkets and Consumers in Africa

Abstract

Supermarkets in urban Kenya have risen from a tiny niche a half decade ago to a fifth of food retail, spreading well beyond the richer consumers to derive more than a third of their sales and half of their customers from low income and poor consumers. This paper explores the patterns and determinants of purchases of the overall food category versus fresh fruits and vegetables, over Nairobi consumer income strata, for purchases from supermarkets versus traditional retailers. Implications are drawn for development programs to help farmers be strategically positioned for change in the food markets facing them.

六种蔬菜对土壤中微量元素富集性的比较研究

研究蔬菜对土壤中微量元素富集性的规律有助于指导海南蔬菜的种植。以建立的该测定方法对6种蔬菜以及土壤中6种微量元素的含量进行比较研究,结果表明:同一蔬菜样品对不同元素生物吸收系数不同,说明富集性不同;不同蔬菜样品对同一元素的生物吸收系数不同,说明富集性不同。     

Determinants of fruit and vegetable consumption in Malaysia: an ordinal system approach*

We examine the socio‐demographic determinants of fruit and vegetable consumption using household survey data from Malaysia. A bivariate ordered probability model is developed by the copula approach. Results for a system of fruit and vegetable servings per week indicate that education, age, ethnicity, income, location of residence, smoking status and health conditions are significant predictors of fruit and vegetable consumption in Malaysia. Policy implications are suggested.     

蔬菜批发市场与蔬菜产业集群的形成与发展——以诸城市龙都街道市场为例

产业集群是一个新的研究领域,但是研究主要是集中在工业集群,对农业集群研究较少,农业集群有一定的特点,决定其有一定的特殊性。本文以山东诸城龙都街道市场为例,从博弈的角度来分析当地的＂怪＂现象,得出交通条件、工业化程度、不同种类的蔬菜、蔬菜品质对蔬菜批发市场的影响并提出了相应的建议。     

蔬菜出口贸易的风险预警：来自重点省份的证据

近年来,山东蔬菜出口规模增长强劲,产业集中度较高,在国际市场上保持较强竞争力,出口市场结构不断优化。但是山东蔬菜出口比重还较小,价格优势正在降低,部分产品竞争力下降,国际市场开拓还不充分。要积极开拓国内外市场实现蔬菜出口市场多元化,实施标准化战略提高蔬菜产品质量,通过调整产品结构和提高蔬菜营销能力增加出口效益,同时要作好风险预警,维护正当贸易利益。
