收入差距不仅是理论研究的热点,也是当前中国面临的重要问题。文章以农村内部收入差距为研究出发点,选取中国1993~2011年相关数据,采用向量自回归模型(VAR)、Johansen协整检验、格兰杰因果检验、脉冲响应、方差分解等方法来定量考察在城镇化及经济增长外部条件下,财产性收入与农村内部收入差距之间的关系。结果表明:传统的城镇化模式及经济增长的非均衡性拉大了农村内部收入差距,农民财产性收入增长缓慢,农民落入“财产性贫困”陷阱的风险正在加大。据此,文章从增加农民财产性收入视角提出,应尽快推进城乡土地市场一体化的新型城镇化,改革土地征用和流转制度,建立和发展农村房产租赁和买卖市场,构建异地(跨区域)宅基地、土地、房屋等财产收益分享机制。
Income gap is not only a hot topic of theoretical researches, but also an important problem for China at present. Beginning from the rural income gap and the relevant data of China from 1993 to 2011, qualitative analysis methods including vector autoregressive model (VAR) ,Jo- hansen cointegration test, Granger causality test, impulse response and variance decomposition are used to analyze the relationship between property income and rural internal income gap under the extemal conditions of urbanization and economic growth. The results show that the traditional ur- banization mode and the non - equilibrium of economic growth widened rural internal income gap, and the property income of farmers grows very slowly, which increased the risks for farmers to go into the "property poverty" trap. Therefore, from the perspective of increasing farmer's property income, the paper proposes that the new - type urbanization which integrates the land of urban and rural areas should be promoted as soon as possible, Land expropriation and circulation system should be reformed, rural house rental and sale market should be established and developed, and the property revenue sharing mechanism of residence land, land and houses across the regions should be established.
