英文文献：Technical efficiency in small-scale irrigation cooperative and its determinants from the perspective of social capital heterogeneity–the case of northwestern China-社会资本异质化视角下的小规模灌溉合作社技术效率及其决定因素——以中国西北地区为例最近更加注意小规模灌溉的技术效率，以实现粮食安全和增加农业发展

英文文献摘要：
Increased attention has recently been given to technical efficiency of small-scale irrigation to achieve food security and increase agricultural development. In this paper, the authors classify irrigation supply management methods as cooperative or non-cooperative, introduce social capital by four dimensions (social network, social trust, social reputation, and social participation), and highlight the impacts of both social capital and cooperative agreements on technical efficiency in the context of small-scale irrigation management. Efficiency is assessed using data envelopment analysis (DEA), and the impact of cooperative agreements and social capital on efficiency is estimated using path analysis. The result of DEA indicates that cooperative and social capital can improve technical efficiency of irrigation. Results of path analysis show that the presence of a cooperative has a positive, significant and direct impact on efficiency. Additionally, the effect of social capital on efficiency is estimated to be reinforced via participation in cooperative methods.
本文作者合作和非合作供应管理分类的灌溉方法,介绍社会资本的四个维度(社会网络、社会信任、社会声誉,和社会参与),并强调社会资本和合作协议的影响技术效率的小规模灌溉管理。采用数据包络分析(DEA)对效率进行评估，采用路径分析(path analysis)估计合作协议和社会资本对效率的影响。结果表明，合作资本和社会资本可以提高灌溉技术效率。路径分析结果表明，合作组织的存在对效率有积极的、显著的、直接的影响。此外，社会资本对效率的影响估计通过参与合作方式得到加强。
