农民家庭经营纯收入影响因素分析:基于岭回归的实证研究

Influence Factors of Farmer Families Net Income: An Empirical Study Based on Ridge Regression

研究农民收入问题对"三农"问题的解决具有重要意义。本文以1985～2005年农村居民家庭经营纯收入数据作为研究对象,通过岭回归分析影响家庭经营纯收入的因素,研究结果表明,年末农用机械总动力与农民经营性收入呈负相关关系;国家财政农业支出、农村集体单位固定资产投资、农村居民个人固定资产投资、有效灌溉面积、化肥施用量与农民经营性收入呈正相关关系;其中农作物播种面积是影响农民家庭经营纯收入的最主要因素。

Studies on the farmers income are very important to solution of the problems in ＂Agriculture, Countryside and Farmer＂. The influence factors of farmers＇ income are analyzed with ridge regression using the family business net income data in 1985-2005. The results show that the total power of farm machinery and farmers income is negatively correlated. The farmers＇ income is positively correlated with national agricultural financial expenditure, investment in fixed assets in rural collective units, individual investment in fixed assets of rural residents, the effective irrigated area, and fertilizer application.
