河南省县域农民纯收入增长差异及其演进格局分析

GROWTH DIVERSITY AND EVOLUTION PATTERN ANALYSIS OF NET INCOME GROWTH OF FARMERS IN THE COUNTIES OF HENAN

利用1996—2007年河南省统计年鉴和典型调研资料,从时间、空间及时空三个角度分析了河南省农民人均纯收入增长的区域差异及其演进格局,根据108个县域1996—2002年、2002—2007年农民收入年增长量进行聚类分析和类型区划分,逐类分析各类型区农民纯收入增长变化的特点,并分析了农民收入区域差异格局形成的成因。结果表明:低农民收入低增长速度区位于河南省南部和东部,空间布局近似"Y"字型,农民的收入主要来源于粮食种植收入;低农民收入高增长速度区分散分布于河南省中部、北部、南部、西部,紧邻市辖区,农民收入主要来源于种植业收入和从事非农产业的工资性收入;高农民收入低增长速度区位于郑州都市圈内,紧邻郑州市,近似环状布局,非农产业收入占农民纯收入的比重较大;高农民收入高增长速度区位于郑州市,紧邻郑州市市辖区,农民收入以工资性收入为主,增收渠道逐步多元化。农业生产条件差异、地理区位不同和非均衡的区域发展政策是农民纯收入地区差异的主要原因。

Based on the analysis of Statistical Yearbook of Henan from 1996 to 2007 and typical research data, the paper analyses regional differences and the evolution pattern of per capita net income growth of farmers in Henan from the time, space and space-time point of view. According to 1996-2002 and 2002-2007 annual growth rate of farmers’ net income of the 108 counties, the paper makes the cluster analysis and regionalization to achieve characteristics of the change in every type of region. Results showed that low growth rate districts of the low income of the farmers in Henan are located in the south and east of the province, where space layout is similar to＂Y＂-shaped. In this region farmers’ income mainly comes from grain-growing revenue. The high growth rate areas of the low rural net income dispersed distribute in the central, northern, southern and western Henan province and close to up-built areas. The income of peasants includes grain-growing revenue and wage income of non-farming industries. Low growth rate districts of the high income of the farmers locate within the metropolitan area of Zhengzhou city, which are close to Zhengzhou city and similar to the layout of ring. The non-agricultural industry revenues account for a larger proportion of net income of farmers in these districts. High growth rate areas of the high income of the farmers locate in Zhengzhou city, where farmers income mainly originate from wage income and gradually become diversified. Differences in agricultural production conditions, geographic location and non-balanced regional development policy are the main reasons for regional differences of net income growth of farmers in Henan province.
