中文摘要：

利用铜川地区桃农调研数据,构建随机前沿生产函数模型,将社会资本各维度加入技术效率损失项,测算桃农生产技术效率水平,分析社会资本对桃农生产技术效率的影响。结果表明：桃农的平均生产技术效率为79.38%,存在着一定程度的技术无效率;在社会资本各维度中,关系网络,集体行动以及信息交流的改善能够显著提高桃农生产技术效率,而干群关系、信任与团结对桃农生产技术效率的影响未通过显著性检验。因此,改善桃农关系网络,集体行动,信息交流状况,是提高桃农生产技术效率的有效途径。

英文摘要：

Using the survey data of peach farmers in Tongchuan area,establish the stochastic frontier production function model with each dimension of social capital joining the technical efficiency loss,calculate planting peach farmers＇ production technical efficiency level and analyse the influence of social capital on the technical efficiency of planting peach farmers＇ production. The results show that average technical efficiency of planting peach farmers＇ production is 79. 38%,with a certain degree of technical inefficiency. In all dimension of social capital,the relationship between network,collective action and information communication can significantly improve the technical efficiency of planting peach farmers＇ production,and the relationship between the cadres and masses improve the technical efficiency of planting peach farmers＇ production but no significant,trust and unity is not significant on the technical efficiency of peach farmers＇ production with the negative effect. Therefore,change relationship between network,collective action and information communication are the effective way to improve he technical efficiency of planting peach farmers＇ production.
