摘要

本研究利用1981年至2018年的年度数据，考察了农业国内生产总值(GDP)和进口对尼日利亚粮食商品价格的影响。采用单位根检验、协整检验和自回归分布滞后(ARDL)模型对所得数据进行分析，评估假设变量对食品价格的长期和短期影响。结果表明，玉米进口价值和汇率在短期内显著影响玉米价格。相比之下，滞后的玉米价格、玉米产量和过去的玉米进口价值是影响本报告所述期间玉米当前价格的因素。此外，大米的滞后价格、大米产量和当年进口大米的滞后价值对尼日利亚的大米价格产生了重大影响。此外，研究表明，小麦滞后价格、小麦进口价值和小麦进口滞后价值对尼日利亚小麦价格的影响具有统计学意义。因此，灵活协调汇率变动的政策可加强国内农业绩效。

Factors Influencing the Prices of Rice, Maize and Wheat Prices in Nigeria

This study examines the impact of agricultural Gross Domestic Product (GDP) and imports on Nigeria’s food commodity prices using annual data from 1981 to 2018. Data obtained were analysed using the unit root test, cointegration test and Autoregressive Distributed Lag (ARDL) model to evaluate the long-run and short-run effects of the hypothesized variables on the food commodity prices. The results reveal that maize import value and exchange rate significantly affect the price of maize in the short-run. In contrast, the lagged price of maize, maize output and the past value of maize imports are the factors that influenced the current price of maize within the review period. Also, the lagged price of rice, rice output and the lagged value of rice imported in the immediate year exerted significant influences on the price of rice in Nigeria. Furthermore, the study indicates that the lagged price of wheat, the import value of wheat and the lagged wheat import value were statistically significant in influencing wheat price in Nigeria. Hence, policies for flexibility in the harmonization of exchange rate movements strengthen domestic agricultural performance.
