利用空间自相关和空间计量方法，分析了长江经济带城市区域经济差异的时空演变，发现差异先增后减，且经济存在显著空间相关性。研究分两阶段考察影响因素，如财政收入、人口密度、财政支出、经济结构和固定资产投资的作用方向与变化。
This article analyzes the regional economic differences in the Yangtze River Economic Belt, using spatial autocorrelation techniques and spatial econometrics method. The result indicates that the regional economic differences become increasing at first and then decreasing. The economy in this area has significant spatial correlation. Besides, the combined effect is significant in high level and low level. In this article, we analyze the influence factors which lead to city regional economic in two stages.
