使用农户模型侧重解释其间接影响,并利用陕西秦岭山区的调查数据验证了这种新的理论解释。实证结果表明:非农兼业户的农业技术效率较高且相对稳定,纯农户的农业技术效率较低且受到家庭结构等因素的制约;有关农业技术效率的政策应当考虑这两个途径的影响。
Using data from a recent household survey in Qinling,the result shows that: the efficiency of non-farm activity is high and stable;human capital and social capital are important for the household's participation in farm activities,which should be considered in relevant policy making.
