Impact mechanism of optimized agricultural machinery input structure on agricultural output:An empirical analysis from grain farmers in Northeast China
To clarify how the rising cost of agricultural labor and tightening land constraints impact the choice of mechanization pathways, the survey data from 1 526 grain-producing households in the three northeastern provinces of China on 2023 are employed to build a “agricultural machinery input structure-factor reallocation-grain output” framework. Continuous agricultural machinery input structure index (share of outsourced machinery services)is embedded in a translog production function, and third-order interaction terms are introduced to empirically analyze the impact of agricultural machinery input structure on grain output and its underlying mechanism. The results show that:1)Agricultural machinery input structure significantly raises grain output, mainly through land expansion and labor-substitution effects; 2)High quality outsourced machinery services and joint purchase models markedly enhance the yield-boosting effect of agricultural machinery input structure; 3)Heterogeneity analyses reveal that the positive effect of agricultural machinery input structure on grain output is more pronounced for small-scale and part-time farmers. Based on the findings, the following policy suggestions are put forward:the government should shift machinery subsidies from purchase-oriented to application-oriented support, improve the quality of outsourced machinery services, promote joint purchase models, and pay special attention to assisting small-scale and part-time farmers, thereby providing a practical pathway for the coordinated advancement of service scale and land scale farming.
