中文摘要：

基于2010年和2012年中国家庭追踪调查（CFPS）数据，本文考察了农业劳动力老龄化及其与社会网络的交互作用对家庭农业经营的影响。研究结果表明，老龄化对家庭农业经营呈显著的负向影响，而农户社会网络能很好地缓解老龄化对农业经营的不利影响，并且社会网络的这一缓解效应会随着老龄化程度的提高而增强。进一步的扩展讨论表明，社会网络的缓冲作用主要体现在缓解老龄农户的劳动力约束，并且社会网络有助于老龄农户流转出土地。本文的发现不仅丰富了老龄化对农业经营领域的经验研究，还为如何提高老龄农户的农业经营收益提供了初步的经验证据。

英文摘要：

This paper investigates the impact of rural aging labor force and its interaction with social network on household＇ s farming by using the data from China Family Panel Studies （CFPS） 2010 and 2012. The results show that aging has a significant negative effect on household＇ s farming, but household＇ s social network can well alleviate the adverse effect of aging, and the alleviating effect can be enhanced with the increase of the degree of aging. Extended discussions show that buffering effect of social network are mainly reflected in easing old farmers＇ labor constraints, also, the social network can help old farmers transfer land. Our findings not only enrich the empirical studies in the field of aging and farming, but also provide preliminary empirical evidence on how to improve old farmers＇ agricultural earnings.
