An Empirical Analysis of the Barriers of the Increasing Income of Farmers in Major Grain-producing Areas

农民增收障碍因素定性分析研究的文献很多,可真正计量实证研究的到目前为止还不多。本文以河南省1978～2007年的农民人均纯收入为样本数据,借助计量回归模型和灰色关联分析方法,对影响河南省农民收入的障碍因素进行了实证研究。结果显示:除政策因素外,农业自身、科技投入、教育等非政策因素也是影响农民收入的主要原因。

Studies on increasing farmer＇s income in qualitative way have been done,but the literature about quantitative empirical analysis,especially in factors of barriers on increasing farmer＇s income,have been scarce so far. Using regressive model and gray relational degree method,the factors affecting farmer＇s income are tested through the sample data on the per capita annual net income of Henan farmers between 1978 and 2007. The results show that not only policy factors but also non-policy factors within self agriculture and in both technology and education investment and so on,are main ones.
