摘要: 【目的】水稻生产是中国广大稻区农民收入和减轻贫困的重要途径,而土地细碎化可能是目前进一步提高农业生产率和减轻农村贫困的主要瓶颈之一。【方法】采用详实的农户调查以及作物水平和地块层次的数据,用两阶段法分析了土地细碎化对中国东南部一个水稻主要产区农户技术效率的影响。【结果】研究区早稻的平均技术效率为0.85,晚稻为0.83,而单季稻为0.79。稻田平均地块大小对早、中、晚3种水稻的技术效率都有显著的正影响。此外,家庭规模和农地规模对3种水稻生产的技术效率也有显著影响。人口较多的家庭或规模较大的农场技术效率较小家庭或小农场要高。【结论】在现有技术状态下,水稻小农户的技术效率仍可得到可观的提高。研究揭示,减轻土地细碎度的项目如果能够与促进农村劳动力市场发育的措施结合起来,将是提高水稻生产技术效率行之有效的途径。

Abstract: Rice farming is important for income generation and poverty reduction in large parts of China. The high degree of land fragmentation, however, may constitute a major bottleneck to increasing productivity and reducing poverty. This paper applies detailed household, crop and plot level data to investigate the impact of land fragmentation on rice producers’ technical efficiency in a major rice growing area of Southeast China, using a stochastic frontier model. Average technical efficiency scores are 0.85 for early rice, 0.83 for late rice, and 0.79 for one-season rice production in our research area. This indicates that with the existing technologies, a considerable productivity improvement can still be reached by addressing the factors constraining technical efficiency increases. Land consolidation can be an important option in this respect, as average plots size is found to have a significant positive impact on technical efficiency for all three types of rice.
