中国省域农民纯收入特征的空间计量经济学分析

提高农民纯收入是解决＂三农＂问题的关键。运用探索性空间数据分析方法对中国农民纯收入特征进行分析,结果表明农民纯收入具有空间相关聚类特性,近10年来并没有明显改变。西部省份之间仍处在低值聚集区,东部省份大都处在高值聚集区,总体上这种不均衡趋势在增强、差距在增大。运用空间计量经济学软件分别进行OLS、SLM和SEM回归分析,探讨农民纯收入影响因素,得知农民纯收入在省域之间不仅存在空间扩散效应,而且影响农民纯收入的因素也具有空间相关性。立足于研究结论基础上,对如何增加农民收入提出一些建议。

A Spatial Econometric Analysis on the Characteristics of Net Income of Farmers of Chinese Provinces

The key to solve the "three rural" issues is to improve the net income of farmers.Characteristic of net income of farmers is analyzed by the method of exploratory spatial data analysis.The results show that the net income of farmers is related to clustering with spatial characteristics.In the past 10 years the situation has not significant change,the western provinces is still in the low accumulation area,but most of the eastern provinces are in high accumulation area.Overall,the imbalance trend and the gap are increasing.Factors affecting the net income of farmers are discussed separately from the OLS,SLM,and SEM by using spatial econometric regression software.The results show that the spatial diffusion effects of farmers net income not only exists between the provinces,but also the factors affecting the net income of farmers have spatial correlation.Based on the above conclusions,some suggestions for increasing the income of the farmers are proposed.
