新疆县域经济空间集聚模式及空间溢出机制研究

A Study of Spatial Agglomeration Mode and Spatial Spillover Mechanism of County Economy in Xinjiang

空间集聚和空间溢出是区域经济差异的两个特征。空间统计中的探索性空间数据分析可以用来探索空间集聚模式,空间计量模型可以发掘空间溢出机制。本文运用探索性空间数据分析和空间计量模型对新疆县域经济进行分析。研究发现:新疆县域经济存在全局空间依赖,而且随着时间的推移,全局空间依赖逐步增加;新疆县域经济的局部空间集聚模式主要是低—低集聚,只有少数县域单位是高—高集聚或低—高集聚;新疆县域经济存在正向的空间溢出,且是经济的直接溢出。

Spatial agglomeration and spatial spillover are the two feature of the regional economic differences. The exploratory spatial data analysis in spatial statistics can be used to explore spatial agglomeration mode and spatial econometric model can explore spatial spillover mechanism. By employing exploratory spatial data analysis and spatial econometric model, this paper analyzes the county economy in Xinjiang and finds that： the county economy in Xinjiang is of global spatial dependence, and with the passage of time, this dependence will gradually increase ; the local spatial agglomeration mode of the county economy in Xinjiang is mainly low - low concentration, only a handful of county unit is either high - high concentration or low - high concentration ; the county economy in Xinjiang has positive space overflow, and the overflow mechanism is the direct overflow of the economy.
