Synergistic Impacts of Dual Agricultural Scale Operations on Mechanical Utilization: Evidence from Rice Production in Jiangsu, China

The development of diverse forms of agricultural scale operations is widely recognized as a cornerstone of modern agricultural management. Most existing studies largely examine land-scale or service-scale operations in isolation and pay little attention to their potential synergies in achieving economies of scale. Using survey data on 1026 plots from 865 rice farmers in Jiangsu Province, China, this study employs fixed-effects regression models to investigate how land-scale and service-scale operations jointly promote scale economies through agricultural machinery utilization. The empirical results reveal three key findings: (i) both land-scale and service-scale operations significantly reduce per-mu (1 mu = 0.067 ha) machinery costs, thereby generating scale economies; (ii) their synergy further amplifies these economies, providing strong evidence of synergy rather than substitution; and (iii) village governance significantly moderates this relationship, with stronger governance reinforcing the synergistic effects between land- and service-scale operations. These findings suggest that dual agricultural scale operations are mutually reinforcing in promoting mechanization. Policy should therefore prioritize their synergistic development and recognize the coordinating role of village collectives.
