农作物机械作业面积与农民收入增长--基于江苏省的协整分析

摘要

Machine-cultivated area, machine-sowed area, machinery plant protection area and mechanical harvest area were used as agricultural machinery operation area indicators from 1990 to 2013 in Jiangsu province, as well as farmer income growth indicator was the per capita net income of rural households.Co-integration test and Granger causality relation test were used to analyze the long-term equilibrium relationship and causal relationship between agricultural machinery operation area and farmer income growth in Jiangsu province.The results indicated the presence of long-term stable equilibrium relationship between agricultural machinery operation area and farmer income growth in Jiangsu province, the role of agricultural machinery operation area in promoting farmer income growth was not significant, but farmer income growth played a significant role in promoting ma-chinery plant protection area and mechanical harvest area.%以1990～2013年江苏省机耕面积、机播面积、机械植保面积和机械收获面积为农作物机械作业面积具体指标，以农村居民家庭人均纯收入作为农民收入增长的指标，利用Johansen协整检验和Granger（格兰杰）因果检验方法研究了江苏省农作物机械作业面积与农民收入增长之间是否存在长期均衡关系及格兰杰因果关系。结果表明江苏省农作物机械作业面积与农民收入增长之间存在长期均衡关系，农作物机械作业面积对农民收入增长的作用不明显，但是农民收入的增长对机械植保面积和机械收获面积作用明显。
