摘要

不同市场的价格知识在很大程度上决定了市场之间信息流动的有效性,这进一步说明了这些市场对价格预测的效率。本研究根据联邦农业和农村发展部项目协调股36个月的二次数据,调查了埃努古州大蕉和香蕉的价格趋势及其在农村和城市市场之间的反应。所使用的方法是对用于衡量空间市场一体化的回归方法的改进。所使用的方法是误差修正模型的简化形式,它有可能提供有关价格形成因果关系的大量信息。结果表明,农村市场每公斤香蕉的平均价格为32.93奈拉,而埃努古市区为46.50奈拉。农村市场和城市市场的大蕉平均每公斤价格分别为43.10奈和46.50奈。虽然农村价格可以用来预测城市市场的香蕉价格,反之亦然,但我们发现只有城市市场的大蕉价格是外生的。经三次滞后后,香蕉和大蕉的价格分别在10%、5%和1%水平上显著。其含义是,价格在不同市场上一起移动,这表明埃努古州香蕉和大蕉的农村价格和城市价格之间存在完美的信息流。尼日利亚园艺科学杂志Vol. 10 2005: pp. 99-104

Retail Rural: Urban Market Integration of Plantain and Banana in Enugu State
The knowledge about price at various markets determine to a large extent the effectiveness of information flow between the markets which further depicts efficiency of such markets for price prediction. This study examined the trend of prices of plantain and banana and their response between rural and urban markets in Enugu State based on a 36-month secondary data from Project Coordinating Unit of Federal Ministry of Agriculture and Rural Development. The methodology used was an improvement in the way regression is used to measure spatial market integration. The method used was a reduced form of an error correction model, which has the potential for providing considerable information about causality in price formation. Results indicated that the average price of banana per kilogram in the rural market was N32.93 whereas it was N46.50 in Enugu metropolis. It was also revealed that average per kilogram of plantain were N43.10 and N46.50 in both rural and urban markets respectively. While the rural price may be used to predict the price of banana in urban market and vice versa, it was discovered that only urban markets price of plantain is exogenous. The prices of banana and plantain was found to be significant at 10 %, 5 % and 1 % level after first difference with three lags. The implication of this is that the prices move together across markets showing that there is perfect information flow between the rural price and urban price of Banana and plantain in Enugu State.
