我国省域乳业发展的空间计量经济分析

Spatial econometric analysis of dairy development in China's provincial regions

以柯布—道格拉斯生产函数为理论框架,运用空间计量经济模型,对2006-2009年我国乳品加工业的区域产出进行了实证分析。结果表明,我国省域乳业产出呈现明显的空间依赖性和空间集聚现象,引入空间效应的空间误差模型克服了普通最小二乘估计设定偏差的问题,对我国省域乳业产值的空间关系具有更强的解释力。

This paper takes Cobb-Douglas production function as the theoretical framework, use spatial econometric model, analyses China＇s regional dairy industry output in 2006 to 2009.The result shows that China＇s regional dairy industry output present significant spatial depen- dence and spatial agglomeration, the Spatial Error Model （SEM） which add spatial effects overcomes the bias of Ordinary Least Squares!OLS） estimation model, and have a stronger explanatory power to the spatial relationships of China＇s regional dairy industry output.
