摘要
本文对土地经营规模与农业生产效率的关系进行文献分析。研究表明,遗漏土壤质量这一变量将会导致经营规模与效率呈“反向关系”,当考虑这一变量时,土地经营规模会对决定土壤质量的肥料投入产生影响。基于有机肥具备跨期效用,研究从土地经营规模与农业可持续发展和技术采纳的角度进行分析,得到经营规模不同导致农户采用农业技术的成本产生差异,从而使农户农业技术采用行为出现差异,进一步影响土壤质量。针对这一影响机制,未来在进行土地经营规模与农业生产力之间关系的研究中需要考虑土壤质量,尤其是影响其物理指标的肥料投入。
This paper takes soil quality as the starting point to analyze the relationship between land operation scale and agricultural production efficiency.The research shows that missing the variable soil quality will lead to an"inverse relationship"between the scale of operations and efficiency.While this variable considered,the size of the land operation will have an impact on the fertilizer inputs that determine soil quality.Based on the intertemporal utility of organic fertilizer,the study analyzes from the perspective of land operation scale and sustainable agricultural development,technology adoption.To obtain the difference in the cost of farmers adopting agricultural technology due to different operating scales,then find that there are differences in farmers’agricultural technology adoption behavior,and finally affect soil quality.In view of this impact mechanism,in the future,soil quality needs to considered in the study of land operation scale and agricultural productivity,especially the fertilizer inputs that affect its physical indicators.
