Mechanisms of how high-standard farmland construction in mountainous areas promotes income growth among impoverished rural households:A case study of Guizhou
Based on the tracking survey data of 500 poverty-alleviated households in moun-tainous areas of Guizhou,this study empirically examines the mechanism by which the con-struction of high-standard farmland promotes income growth for poverty-alleviated house-holds from the perspectives of resource endowment improvement,agricultural production ag-gregation,and scale effects using a double difference fixed effects model.The results indi-cate that:(1)The fragmented nature of cultivated land in mountainous areas hinders the large-scale planting of high-standard farmland,but centralized agricultural machinery servic-es save labor input,utilize fallow land resources,and expand income sources.(2)Annual damage to high-standard farmland in mountainous areas due to disasters leads to seasonal growth in wage income for poverty-alleviated households through repeated repairs,prompt-ing households to value the limited land resources for ensuring food security and strengthen-ing their willingness to return to hometowns for work.(3)In mountainous areas,the use of agricultural machinery is more significant for daily maintenance,disaster prevention,and re-planting than for cultivation and harvesting,and labor substitution through machinery can promote the scale of farming practices.Therefore,the construction of high-standard farmland in mountainous areas should focus on the characteristics of impoverished households having barren land resources and being located in mountainous areas,utilize agricultural machinery services,diversify income sources,overcome limitations on scaling cultivation,and achieve the scale of operational models.
