The Effect Of Labor Structure On Agricultural Production Technical Efficiency Under The Background Of Rural Revitalization

China is a large agricultural country,agriculture is the basis for the development of other industries.Since China’s reform and opening up,more and more rural young labor force “go to sea” business,rural surplus labor force continuously into the city.This process will inevitably bring about changes in the structure of the labor force,which is embodied in the change of the gender structure of the labor force,that is,the degree of gender balance;the change of employment structure,that is,the situation of non-agricultural production personnel,etc.In addition,labor is the most active part of the input factors in the agricultural production process,and the change of labor structure will affect agricultural production.Studying the impact of rural labor structure on the technical efficiency of agricultural production is of great significance for the government to regulate agricultural production,improve agricultural comprehensive production capacity,ensure food security,and promote rural revitalization.Based on human capital theory and labor transfer theory,this paper theoretically analyzes the influence path of labor structure on agricultural production efficiency.Starting from the general requirements of rural revitalization,capital,human and financial indicators are selected,and the principal component analysis method and stochastic frontier method are comprehensively used to measure the technical efficiency of agricultural production in 100 prefecture-level cities in China from 2010 to 2020.Tobit model is used to explore the direct impact of rural labor structure on agricultural productivity,and to observe whether the direct impact effect will be affected by rural revitalization strategy and regional heterogeneity.In this paper,the urbanization level is introduced into the panel model,and the panel threshold regression method is used to analyze the nonlinear mechanism of rural labor force structure on agricultural production technical efficiency.The following conclusions are drawn : the gender structure of rural labor force has a significant positive impact on agricultural production efficiency and there is a double threshold effect.The transfer of rural labor force has a significant negative impact on agricultural production efficiency.Based on the above conclusions,this paper proposes to optimize the allocation of factors and choose the rural revitalization model in line with its own development according to local conditions;improve the quality of the population,strengthen agricultural production technology training;scientific construction of modern agricultural transfer labor employment service platform;increase rural financial support,provide financial security and other targeted recommendations.
