摘要:
农户是单独还是联合进行生产经营决策关系到如何细化我国"统分结合"的农业经营体制问题。本文关注了农户在土地投资中的决策模式选择，并认为由于我国地块面积非常狭小，除了土壤改良投资以外，农户们在面积狭小、紧挨着的地块上进行的大部分长期投资（主要是基础设施和改变用途投资）表现出强烈的规模经济、外部性和公共物品特征，联合投资将是他们的合理选择。基于江苏省18县4796个地块样本，本研究一方面揭示农户长期土地投资的联合性，另一方面分析地块规模对农户投资决策的影响。研究发现，农户在地块上进行的基础设施与改变用途投资中接近65%属于联合投资，地块规模扩大可以显著提高农户单独投资的概率，并促进投资项目决策由联合决策向单独决策转变。这说明对这两类投资而言，地块规模扩大是农户进行单独自由决策的前提；小规模地块主要依赖农户间的联合投资决策。相应的政策含义包括：一方面扩大地块规模提高农户单独投资的激励；另一方面则组织、协调好农户的联合投资决策并加强政府的公共投资。而在地块规模充分扩大，集体或联合决策内化为个体自由决策之前，对农户个体地权的强化对于刺激基础设施与改变用途投资的意义可能是有限的。
Abstract:
The issue that farmers make their production decision individually or collectively is related to the boundary between the free market and government regulation. This paper investigated farmers’ decision making mode in land investment area. As China’s agricultural production is characterized by small scale plot and fragmented land, the land investments, such as infrastructure and use-change investment, are characterized by strong economies of scale, externalities and features of public goods for the tiny adja-cent plots. Jointed investment becomes a reasonable choice for them. Based on the sample of 4796 plots collected from 18 counties in Jiangsu Province, this study explores the jointed decision in land invest-ment and the influence of plot scale on it. It finds that 65% of infrastructure and use-change investment decisions are made jointly by farmers. The increase of the plot scale significantly increases farmers’ indi-vidual investment but not the jointed investment. These results indicate that for these investment, free individual decision relies on the scale of plot and the jointed decision-making dominates regarding small -scale plots. The policy implications include:promoting land consolidation to increase individual in-vestment, coordinating the joint investment decision of farmers, and enhancing the role public invest-ment. The significance of individual land rights protection may be limited before the plot scale is big e-nough and the collective or joint decision is internalized into individual free decision.
