摘　　要：基于马克思主义经济学资本有机构成理论,构建物化技术进步的农业生产函数,探究农业资本有机构成影响农业经济增长的理论逻辑。运用1978—2020年的中国省际面板数据进行实证分析,并检验农业技术进步和农业产业集聚机制。研究表明:1978年以来,中国农业资本有机构成呈上升趋势,并趋向于完全由农业资本存量变动主导;农业资本有机构成对农业经济增长的影响呈现倒“U”型特征,存在最优农业资本有机构成及其决定的最优农业经济增长路径;现实农业资本有机构成与最优农业资本有机构成还存在明显差距,提升农业资本有机构成对于促进农业经济增长仍有可观空间;在中部地区、平原丘陵地区、农业资本有机构成较低地区、非粮食主产区、农业经济规模或农业资本存量较高地区,提高农业资本有机构成能发挥更大的作用。促进农业技术进步、提升农业产业集聚水平有利于增强农业资本有机构成对农业经济增长的作用,但并不会显著改变两者之间的倒“U”型关系特征。Based on Marx′s theory of organic composition of capital,this paper constructs an agricultural production function of materialized technological progress,exploring the theoretical logic of the organic composition of agricultural capital affecting agricultural economic growth,then uses China′s provincial panel data from 1978 to 2020 for empirical analysis,and tests agricultural technology progress mechanism and agricultural industry agglomeration mechanism.Research shows that since 1978,the organic composition level of agricultural capital in China has shown an upward trend and tends to be completely dominated by changes in the stock of agricultural capital.The impact of the organic composition of agricultural capital on agricultural economic growth presents an inverted"U"shape,with the existence of the optimal organic composition of agricultural capital and the optimal path of agricultural economic growth determined by it.There is still a significant gap between the actual level of organic composition of agricultural capital and the optimal level of it.Improving the organic composition of agricultural capital still has considerable space for promoting agricultural economic growth.In central regions,plain and hilly regions,regions with lower organic composition of agricultural capital,non-food producing regions,and regions with higher agricultural economic scale and agricultural capital stock,increasing the organic composition of agricultural capital can play a greater role.Promoting the progress of agricultural technology and enhancing the level of agricultural industry agglomeration is beneficial for enhancing the role of organic composition of agricultural capital in agricultural economic growth,but it will not significantly change the inverted"U"shaped relationship between the two.
