摘要

该研究实证分析了需求结构和garri在尼日利亚伊莫州的Owerri North L.G.A.的消费,并试图确定影响garri在低、中、高收入水平的月度预算份额的因素,估计garri需求的自身价格、交叉价格和收入弹性,以及确定影响对特定garri品牌偏好的因素。为了实现这一任务,使用简单的随机和判断抽样技术来选择社区,他们的市场和80名受访者。数据收集采用一套预测的结构化问卷。本研究采用多元回归模型、需求弹性指标和logit回归模型作为分析工具。半对数多元回归分析结果表明,家庭规模、garri价格和特定水平下的月收入是影响低收入消费者每月garri预算份额的关键因素。所有变量的综合效应解释了1.0%风险水平下garri每月预算份额变化的77.8%。以指数函数形式作为主导方程的多元回归分析结果显示,中等收入消费者每月教育预算份额的关键和显著决定因素是受教育年限、家庭规模和月收入。所有变量都能解释中等收入消费者每月预算份额的81.8%的变化。garri需求的自身价格弹性为0.03,而garri与fufu、samovita、山药地板和木薯地板的交叉弹性分别为2.3、1.8、1.4和1.4。garri需求的收入弹性为0.3。logistic回归估计表明,价格、颜色感知、年龄和受教育程度是影响鸡鸡偏好的决定因素,在1.0%的风险水平上具有统计学意义。有人建议,不同收入阶层(低、中、高)的所有消费者都有必要光顾各种颜色的肉酱,以推动农民生产更多的肉酱,增加收入。

Demand Structure and the Consumption of Garri in Owerri North Local Government Area of Imo State, Nigeria.
The study analysed empirically the demand structure and the consumption of garri in Owerri North L.G.A. of Imo state, Nigeria and sought to determine the factors that influence the monthly budget share for garri at low, med iu m and high income levels, estimate own price, cross price and income elasticit ies of demand for garri and as well to determine the factors that influence preference for a part icular garri brand. In order to achieve this mandate, Simple random and judgmental samp ling techniques were used to select communit ies, their markets and 80 respondents. A set of pretested and structured questionnaire was used in data collection. Mu ltiple regression model, demand elasticity indicators and logit regression model were the tools of analysis adopted for th is study. The result of the mult iple regression analysis with semi log, as lead equation showed that the critical and significant determinants of monthly budget share for garri among lo w inco me consumers were household size, price of garri and monthly incomes at given levels. The comb ined effect of all the variab les explained 77.8% of the variation in the monthly budget share for garri at 1.0% risk level. The result of the mult iple regression analysis with exponential functional form as the lead equation showed the critical and significant determinants of monthly budget share for garri among the middle income consumers were nu mber of years spent in school, household size and monthly inco mes. All the variables exp lained 81.8% of the variation in the monthly budget share for garri among the middle income consumers. The result also showed that the own price elasticity of demand for garri was 0.03 while cross elasticity of demand fo r garri and fufu, samovita, yam floor and cassava floor were 2.3,1.8, 1.4 and 1.4 respectively. The inco me elasticity of demand for garri was 0.3. The logistic regression estimat ion showed that the determinants for preference of garri include price, colour perception, age and education which were statistically significant at 1.0% risk level. It was reco mmended that there is the need for all consumers in different income strata (low, mediu m and high) to patronize garri of all colours in order to act as impetus to farmers to produce more and increase their inco me.
