An Economic Analysis of Rice Cultivation Pattern Selection

As the fundamental operational units of agricultural production, farmers make production decisions based on the principle of household income maximization. This study draws on data from a micro-level survey of rice farmers conducted in Jiangxi Province from November 2022 to August 2023, which yielded 1014 valid observations to examine two rice cultivation patterns—double-cropping rice (DCR) and rice–rapeseed rotation (RRR)—in order to analyze the economic effects of farmers’ cultivation choices on rice production. Additionally, a heterogeneity analysis is performed, taking into account labor force size, intergenerational differences, and operational scale. The results indicate that (1) farmers adopting the RRR pattern experience a significant increase in per-unit-area profit, thereby enhancing household income, with gains ranging from 16.95% to 153.20%. (2) The heterogeneity analysis reveals that the economic effects of labor availability, generational differences, and operational scale are not uniform. Ample labor resources strongly support rice production; older-generation farmers’ intensive farming methods are more suitable for RRR, and land expansion is constrained by scale thresholds. Based on these findings, it is recommended to optimize the allocation of production factors such as land and labor, and to guide farmers in adapting their rice cultivation strategies accordingly.
