JDS | 中国家庭农业的社会交往与溢出效应【转】
摘要简单翻译：
本文旨在测试社会互动和投入溢出效应对混合水稻生产（有机和常规农业）家庭农场农业绩效的影响。利用来自中国村庄的追踪调查数据，我们采用空间计量经济学的空间德宾模型（SDM）来解释社会互动效应与溢出效应和控制技术异质性。我们的分析揭示了负面的社会交互效应，表明邻近地块的产量增加导致地块本身的产量下降。我们还发现输入溢出效应。劳动力，资本成本，水和有机农药具有正溢出效应，而外部营养素（氮和磷酸盐）具有负溢出效应。因此，我们的研究要求更好地了解农民在促进可持续家庭农业方面的社会互动和溢出效应。
Abstract:
This paper aims to test the effects of social interaction and input spillovers on the agricultural performance of family farms in mixed paddy rice production (organic and conventional farming). Using survey panel data from a Chinese village, we adopt a Spatial Durbin Model (SDM) derived from spatial econometrics to disentangle the social interaction effect from spillover effects and to control for technological heterogeneities. Our analysis reveals a negative social interaction effect indicating that an increase in the yield of neighbouring plots leads to a decrease in the yield of the plot itself. We also find input spillovers. Labour, capital costs, water and organic pesticides have positive spillovers while external nutrients (nitrogen and phosphate) have negative spillover effects. Our study thus calls for a better understanding of social interactions and spillover effects among farmers in the promotion of sustainable family farming.
