The Spatial-Temporal Evolution of Spatial Pattern of Rural Residents’ Net Income at County Level in Jiangsu
运用数理统计和空间统计方法，分析了1995-2010年江苏省县域农村居民人均纯收入的空间差异、极化与自相关趋势，并探讨了收入与增长率的热点演变，为促进农村经济协调发展提供参考。
In the paper,spatial disparity,polarization and autocorrelation trend of rural residents’per capita net-income at county level from 1995 to 2010 in Jiangsu were estimated based on mathematical statistics analysis and spatial statistical analysis methods.And then,spatial pattern of rural residents’per capita net-income and rural residents’income growth rate were discussed by Exploratory Spatial Data Analysis method(ESDA),the evolution trend of rural residents’income and rural residents’income growth rate hotspots were also discussed.Results show that:(1) The regional absolute discrepancy of rural residents’net-income was widening fluctuately,while regional relative discrepancy displayed a fluctuant reduced trend;(2) Rural residents’net-income spatial pattern in Jiangsu showed a strong trend of spatial natural correlation,the similar units clustered in space;(3)Although the spatial pattern of rural residents’net-income growth rate also showed a strong trend of spatial natural correlation,the development of the rural residents’net-income growth framework is likely to be unstable in the aspect of spatial distribution,hotspots areas switching quickly between south Jiangsu and north Jiangsu,the spatial gather trend of every growth type regions decreased while the random distribution situation enhanced.And at last,the driving factors of the evolvement of rural economic development framework were identified from the following aspects: the economic geographical location,industrial and urban-rural structure,regional economic policy and openness economy level and so on,and at last the suggestions were proposed to drive rural economy in Jiangsu comprehensively and harmoniously develop.
