Despite decades of decline in global malaria rates, trends are beginning to change; in the last few years, progress has stalled and even reversed in some places. The ever-increasing scale of land transformation is likely a factor in contributing to this shift in global malaria progress, as recent research makes links between activities such as agriculture, timber harvest, and aquaculture to mosquito vectorial capacity. We combine these insights with political economy perspectives from sociology to understand the larger structures that facilitate the disproportionate concentration of primary sector activities in poorer countries. We predict that less-developed countries with increasing economic specialization in the primary sector will have heightened incidence of malaria over time. We employ a two-way fixed effect panel regression analysis of 72 malaria-endemic countries from 2002 to 2019. Our results confirm our predictions. This study brings to light the large-scale forces that lead some countries to specialize in economic activities that serve to enhance malaria vulnerabilities.

粮食种植、喂养疾病：欠发达国家初级部门专业化和疟疾发病率

尽管全球疟疾发病率几十年来一直在下降，但趋势正在开始改变。过去几年，进展停滞不前，有些地方甚至出现倒退。不断扩大的土地改造规模可能是导致全球疟疾进展转变的一个因素，因为最近的研究将农业、木材采伐和水产养殖等活动与蚊媒能力联系起来。我们将这些见解与社会学的政治经济学观点相结合，以了解促进初级部门活动过度集中在较贫穷国家的更大结构。我们预测，随着时间的推移，初级部门经济专业化程度不断提高的欠发达国家的疟疾发病率将会升高。我们对 2002 年至 2019 年 72 个疟疾流行国家进行了双向固定效应面板回归分析。我们的结果证实了我们的预测。这项研究揭示了导致一些国家专门从事有助于增强疟疾脆弱性的经济活动的大规模力量。
