According to the World Health Organization (2020), many parts of the world have demonstrated potentials for acute hunger and famine. Many countries in Sub‐Saharan Africa (SSA) actively feature in this category due to geopolitical crises and other humanitarian challenges. Despite efforts by SSA governments, agricultural productivity continues to be inadequate in meeting nutritional needs across Africa. Thus, in the presence of economic expansion, vast land, and labor resources, this study investigates the role of mechanization as an important factor for increased agricultural productivity in SSA. Data on 25 SSA countries over 17 years are used. Empirical results from System Generalized Method of Moments show that among other variables, mechanization is a significant factor influencing agricultural productivity. Consequently, in light of the bid for higher agricultural productivity, government investment in mechanization becomes a priority. Also, apart from the fact that many African countries are at the point where more land must be brought under development to satisfy expanded market needs, larger investments in mechanization appear imperative.

撒哈拉以南非洲实现可持续粮食安全的途径：农业机械化的作用

根据世界卫生组织（2020年），世界上许多地方都表现出了严重的饥饿和饥荒的潜力。由于地缘政治危机和其他人道主义挑战，撒哈拉以南非洲（SSA）的许多国家都积极地属于这一类。尽管撒哈拉以南非洲各国政府作出了努力，但农业生产力仍然不足以满足非洲各地的营养需求。因此，在存在经济扩张，广阔的土地和劳动力资源的情况下，本研究调查了机械化在撒哈拉以南非洲地区作为提高农业生产率的重要因素的作用。使用了17年中25个SSA国家的数据。系统通用矩量法的经验结果表明，在其他变量中，机械化是影响农业生产率的重要因素。所以，考虑到提高农业生产率的要求，政府对机械化的投资成为当务之急。此外，除了许多非洲国家处于必须开发更多土地以满足不断扩大的市场需求这一事实之外，机械化方面的更大投资似乎势在必行。
