Spatial Statistics Analysis of China's Planting Geographic Agglomeration
基于1980-2012年中国29个省份的农作物播种面积面板数据，运用空间统计方法分析种植业的空间依赖性和异质性，发现其呈现显著的正空间自相关、非随机地理集聚和核心-边缘分布模式。
Based on the panel data of cropsown area of China's 29 provinces during 1980-2012, this paper apply spatial statistics methods to analyzing planting's spatial dependence and spatial heterogeneity at the geographical dimension of province, and further exploring the characteristics and changing trends of planting's geographic agglomeration. Our empirical result follows: in China, planting whether in the overall or local region, shows a significant positive spatial autocorrelation, with significant pattern of non- random geographic agglomeration and obvious spatial correlation and spatial heterogeneity, and with strong spatial spillover effects among provinces; at the same time, China's planting appeared obviouscore- peripheryspatial distribution model, and the core region of high- high agglomeration significantly expanded.
