Abstract

Rice plays an important role in the food and nutrition security of the Mozambican population and has been importing rice to meet growing consumption needs. There are several studies regarding demand of imported rice worldwide. However, it is noted that despite the importance of imported rice in national consumption, the empirical and quantitative studies on the demand for imported rice in Mozambique are scarce. This study results from the need to contribute to filling the information gap by providing the quantification of the impact of income and price on the consumption of imported rice. Based on monthly rice import data from 2011 to 2020, obtained from INE, the Source Differentiated Almost Ideal Demand System (SDAIDS) model and the Seemingly Unrelated Rules (SUR) approach are applied to estimate demand systems for imported rice. The period was chosen due to availability of data. The results of this study show that the national production of rice still does not cover internal needs, so the country resorts to imports to fill the deficit. The elasticities of demand for rice imported into Mozambique show that all income elasticities of demand are statistically significant, except for “other countries” or Rest of the World. The results also show that when income increases by 1%, the demand for rice increases by 1.2% when coming from “Pakistan”, and by 1.1% when coming from “Singapore”, by 1.03% for “Vietnam”; and in for those from “Myanmar” (1.1%), which suggests that rice from these countries can be classified in the luxury goods category. The results also illustrate that when the price increases by 1%, the quantities demanded decrease, on average, by 1.06% for rice coming from “Pakistan”; by 1.06% for those from “Singapore”; 1.22% for those from “Myanmar”; 0.96% for those from “Vietnam”; by 0.89% for “India”; by 0.79% for “China”; in 0.974% for “Thailand” and in 0.56% for those coming from “other countries”. The low levels of production and productivity show that it is still a challenge to guarantee rice self-sufficiency in Mozambique, and efforts to improve supply must continue, since the country's dependence on imported rice can potentially create conditions of vulnerability and insecurity and adverse market effects have competitive advantages.
莫桑比克进口大米需求量(2011 - 2020 年)
大米在莫桑比克人口的食品和营养安全方面发挥着重要作用,莫桑比克一直在进口大米,以满足日益增长的消费需求。全球有多项关于进口大米需求的研究。然而,我们注意到,尽管进口大米在国民消费中占有重要地位,但有关莫桑比克进口大米需求的实证和定量研究却很少。本研究正是出于填补信息空白的需要,量化收入和价格对进口大米消费的影响。根据从国家统计局获得的 2011 年至 2020 年每月大米进口数据,采用源差异几乎理想需求系统(SDAIDS)模型和看似不相关规则(SUR)方法来估计进口大米的需求系统。由于数据的可获得性,选择了这一时期。研究结果表明,国家的大米产量仍不能满足国内需求,因此需要通过进口来填补缺口。莫桑比克进口大米的需求弹性表明,除 "其他国家 "或世界其他地区外,所有收入需求弹性在统计上都是显著的。结果还显示,当收入增加 1%时,来自 "巴基斯坦 "的大米需求量增加 1.2%,来自 "新加坡 "的大米需求量增加 1.1%,来自 "越南 "的大米需求量增加 1.03%,来自 "缅甸 "的大米需求量增加 1.1%。结果还表明,当价格上涨 1%时,"巴基斯坦 "大米的需求量平均减少 1.06%;"新加坡 "大米的需求量平均减少 1.06%;"缅甸 "大米的需求量平均减少 1.22%;"越南 "大米的需求量平均减少 0.96%;"印度 "大米的需求量平均减少 0.89%;"中国 "大米的需求量平均减少 0.79%;"泰国 "大米的需求量平均减少 0.974%;"其他国家 "大米的需求量平均减少 0.56%。较低的产量和生产率表明,莫桑比克在保证大米自给自足方面仍然面临挑战,必须继续努力改善供应,因为该国对进口大米的依赖可能会造成脆弱和不安全的状况,不利的市场影响会产生竞争优势。
