中文摘要：

以江西省为例，在江西26县32乡镇32村1058户农户抽样调查的基础上，应用二元定距相关分析法和多元回归分析方法，定量研究粮食主产区农户家庭劳动力就业非农化行为的主要影响因素。结果表明，农户所处村域环境、户主年龄、户主职业、人均耕地面积、家庭务工收入比、农户种粮风险认知、种粮预期收益评价等因素对农户家庭劳动力就业非农化行为均有不同程度和不同方向的影响，其中家庭务工收入比的正向作用最大，种稻收益预期的反向作用最大。同时在理论与实证研究的基础上，提出因地制宜地引导农户适度规模经营、鼓励青年农民发展粮食生产、完善农业扶持政策等政策建议。

英文摘要：

Based on the survey of 1058 farm households of planting paddy rice in 32 villages of 26 counties,Jiangxi Province,the paper employed the Bivariate Correlations Analysis and Multiple Linear Regression to analyze the main affecting factors of non-farm activities in rural labor employment in farm households in China＇s major grain producing areas.Results from Empirical study show that to some degree and in various directions such farm household-concerning factors may influence non-farm activities as geographic conditions of inhabitation,ages and the professions of farm household heads,the average cultivatable lands per capita,proportion of non-farm income to farm income,risk assessment of grain culture,and expected earning assessment,etc.,and in these factors,the positive effects of non-farm income are the strongest on farm income,while the negative effects of expected earning assessment is strongest.Based on these theoretical and empirical studies,this paper raises suggestions like guiding farm households to develop in a proper scale in line with local conditions,encouraging young farmers to increase grain production,and perfecting agriculture-aid and agriculture-support policies.
