世界水产品出口空间自相关分析

描述了世界水产品消费情况,阐述了水产品出口对于提高低收入食品匮乏国家人们蛋白摄入水平、增加外汇创收的重要意义。计算了2003-2008年世界水产品出口全局Moran’s I指数,并进行了局部分析,发现世界水产品出口存在显著空间集聚特征,但是集聚程度逐渐下降。估计了世界水产品出口空间滞后函数和空间误差函数,量化分析本国（地区）水产品出口对周边临近国家（地区）水产品出口的空间自相关关系。实证分析表明,本国（地区）水产品出口对周边临近国家（地区）水产品出口正向空间依赖关系显著。

Analysis on Spatial Autocorrelation of World Export of Fishery and Aquatic Products

The paper describes the world consumption of fishery and aquatic products,and importance of fishery and aquatic products export to the low income and food deficit countries in terms of protein intake and foreign exchange accumulation.It calculates Global Moran＇s I indexes and local indicators of spatial association of world fishery and aquatic products export during 2003-2008.The paper also estimates spatial lag functions and spatial error functions of fishery and aquatic products export during the same period of time,and quantifies spatial dependence of fishery and aquatic products export.Empirical analysis reveals that positive spatial dependence of fishery and aquatic products export of a country（region） on its neighboring countries（regions） does exist.
