区域经济发展水平与用水效率的空间计量分析
Spatial Econometric Analysis of the Relationship Between Regional Economy Level and Water-Use Efficiency
摘要
Abstract
For the purpose of improving water⁃use efficiency, this paper took the economic development level and geographic factors into consideration to reveal the spatial correlation between the level of regional economic development and water⁃use efficiency. Based on the data of per capita GDP of each region and ten thousand RMB Yuan water consumption of Jiangsu Province in 2012, it built spatial econometric models and compared the analysis results of these three models:ordinary regression model, spatial lag model ( SLM) and spatial error model ( SEM) . The results show that there is a significant spatial correlation between the level of regional economic development and water⁃use efficiency of Jiangsu Province;Moran's I passes the test of significance and R2 is always greater than 0.75, and the spatial lag model ( SLM) fits best;water⁃use efficiency in Jiangsu Province is influenced by the level of local economic development and the water⁃use efficiency in the surrounding urban areas.关键词
