摘要: 本文采用2012~2023年西部地区农产品贸易统计数据，运用柯布–道格拉斯生产函数模型，分析农产品出口贸易、农产品进口贸易、农村物质资本投入、农村人均人力资本投入及农业技术水平对农民收入的影响，结果表明：农产品出口贸易、农村物质资本投入及农业技术水平正向影响农民收入，农产品进口贸易对农民收入有显著的负向影响，并提出有效拓宽西部地区农民增收渠道、提升农业效益、推动西部地区农业可持续发展的政策措施。

Abstract: This paper uses statistical data on agricultural product trade in China’s western region from 2012 to 2023 to analyze the impact of agricultural export trade, agricultural import trade, rural physical capital investment, per capita rural human capital investment, and agricultural technology level on farmers’ income, employing the Cobb-Douglas production function model. The results show that: agricultural export trade, rural physical capital investment, and agricultural technology level have a positive impact on farmers’ income, while agricultural import trade has a significant negative impact. Furthermore, this paper proposes policy measures to effectively expand channels for increasing farmers’ income in the western region, improve agricultural efficiency, and promote the sustainable development of agriculture in China’s western region.
