公路交通与经济发展空间相关性及收敛性分析

为描述公路交通设施的空间分布状态,评价其与经济发展的空间相关效应,引入空间计量经济学分析中国公路交通设施的空间相关性和收敛性，探讨其与区域经济发展的关系.结果表明，中国公路交通设施在空间上存在显著的空间自相关性，且显著性不断增强，呈现出明显的空间集聚特征，东部沿海地区及中部的长江流域地区聚集程度高，西部聚集程度低，东西差异明显；我国公路交通设施不存在α 收敛和绝对β 收敛，而引入控制变量后，存在条件β 收敛并显著,说明我国公路交通设施发展还取决于其他影响因素；公路交通设施和区域经济发展在空间上呈现正相关并高度显著，显著性高的地方主要集中在川、云、贵地区；我国区域经济发展不存在α 收敛和绝对β 收敛，而引入控制变量后，条件β 收敛显著.说明公路交通设施的发展能够促进区域经济发展.

Spatial Correlation and Convergence between Highway and Economic Development in China

The spatial econometrics theory and method is applied to analysis the spatial difference and correlation between highway and economic development in China. The conclusions are that, there is obvious spatial correlation and convergence between highway and economic development in China. The significance of it becomes more and more strength and has a striking spatial aggregation. The aggregation degree of eastern coastal area and central area of the Yangtze River is much higher than the West of China, and has significant difference between them. Highway traffic infrastructure do not have sigma convergence and absolute beta convergence. But when applies in control variable, it has significant conditional beta convergence. Highway traffic infrastructure and the regional economy development have highly significant positive spatial correlation. And the significant high place mainly in Sichuan, Yunnan and Guizhou. The regional economic development has no sigma convergence and absolute beta convergence, but has obvious conditional beta convergence. It illustrates that the development of highway transportation infrastructure can promote the regional economic development.
