Study on Relationship Between Moderate Farmland Operation Scale and Irrigation Efficiency
The research on the optimal farmland operation scale and irrigation water use efficiency has always been a focal point in the field of agricultural economy.However,there have been limited achievements in integrating these two aspects into a unified theoretical framework.By reviewing the latest research frontiers on moderate farmland operation scale and irrigation efficiency,studies on moderate operation scale rarely consider irrigation efficiency were identified,while research on irrigation efficiency often included land operation scale as a key influencing variable.It was noted that there existed a positive,negative or'inverted U-shaped'curve relationship between these two factors.Moreover,the primary factors contributing to the negative correlation between these two variables were farmers'self-interested water usage behavior and farmland fragmentation which were uncovered.Conversely,agricultural infrastructure intensification,economies of scale,and optimized cropping structures accounted for the positive relationship.The high cost of water-saving facilities and diminishing returns to scale were responsible for the curvilinear association.Under the context of"small plots merging into a large plot"and accelerating the development of water-saving agriculture,future researches should focus on elucidating the mechanism for optimizing both farmland management scale and irrigation efficiency,conducting empirical studies on this dual-objective optimization,establishing a game framework among different stakeholders involved in the process,and summarizing successful case experiences of moderate farmland management scale at home and abroad.
