Impact of Labor Aging on Grain Production Efficiency and Its Mitigation Path
Based on human capital theory and farmer behavior theory,this paper establishes a theoretical analysis framework of"human capital-technological progress-grain production efficiency",explains the im-pact mechanism of labor aging on grain production efficiency and the regulatory effect mechanism of agri-cultural mechanization,and then collects the micro survey data of Sichuan province grain growers in 2022 for empirical analysis and test.The results show that:the relationship between labor aging and grain pro-duction efficiency is not a simple positive or negative relationship,but an inverted U-shaped trend with farmers aging,and the population aged 55-60 is the most efficient.When farmers are over 60,the tech-nical efficiency,land productivity and labor productivity of grain production show a downward trend;Ag-ricultural mechanization not only directly improves farmers'grain production efficiency,but also plays a significant positive regulatory role in the impact of aging on technical efficiency,land productivity and la-bor productivity,that is,alleviate the adverse impact of aging on grain production efficiency.Therefore,the government should focus on promoting the high-quality development of agricultural mechanization in the whole process,promoting the organic connection between elderly farmers and modern agriculture,and optimizing the population structure of agricultural labor force by "introducing" and "cultivating" at the same time.
