Empirical Analysis on Relationship Between Agricultural Land Intensive Utilization and Income Growth of Rural Residents in Henan Province:1978-2012
基于河南省1978-2012年数据，用遗传算法-BP神经网络测算农业土地集约利用水平，通过协整分析、脉冲响应和方差分解，发现集约利用与农民收入存在长期均衡关系，短期有微弱推动作用。
Based on relevant data from 1978 to 2012 of Henan Province, this paper calculates the levels of agricultural land intensive utilization by using Genetic Algorithm-BP ANN.On this basis, by using co-integration analysis, impulse response function and Variance decomposition, we analysised the dynamic relationship between agricultural land intensive utilization and income growth of rural residents and got conclusions as follows: There exists long-term cointegration relationship between agricultural land intensive utilization and income growth of rural residents in Henan Province.When the agricultural land intensive utilization levels increase of 1 Units,0.4075 Units of income growth of rural residents increase. Agricultural land intensive utilization had faintly impetus for income growth of rural residents in the short term,and they have Granger causal relationship to each other.The impulse response function and variance decomposition shows that with the increase of the agricultural land intensive utilization level,the indices of peasant percapita income will promote too. Enhance its explanation capability of the income growth of rural residents over time.
