水资源非农化的区域差异及收敛性研究

Research on regional differences and convergence of non-agriculturization of water resources

随着我国工业化、城镇化的快速发展,水资源非农化态势愈发明显。以31个省(市、自治区)为研究对象,应用描述性统计分析、泰尔指数等技术方法系统刻画了2000-2016年间水资源非农化的空间格局及区域差异,同时借鉴经济增长理论中的收敛性检验方法,对水资源非农化的区域差异进行了收敛性检验。结果表明:水资源非农化利用的地区间差异显著,南方地区高于北方地区,东部及中部地区高于西部地区;2000-2016年31个省(市、自治区)水资源非农化利用总体无明显的σ收敛特征,但整体层面及各地区都存在绝对β收敛和条件β收敛。研究结果可为各地政府制定科学合理的水资源配置方案提供参考。

With the rapid development of China's industrialization and urbanization,the trend of non-agriculturalization of water resources is more obvious.Adopting methods of descriptive statistical analysis and their index,this paper systematically studied the spatial evolution and the regional differences of water resources'non-agriculturization in the 31 provinces of China from 2000 to 2016.Meanwhile,convergence test on the regional differences was performed using convergence testing method from theory of economic growth.The results showed that non-agriculturization of water resources is on wavelike rising trend,and the difference of non-agricultural utilization of water resources among regions is significant,the southern region is higher than the northern region,the eastern and central regions are higher than the western region.The result of the estimate with the panel data showed that there is no obviousσconvergence in China's non-agriculturization of water resources from 2000 to 2016,but there are absoluteβconvergence and conditionalβconvergence for both the whole country and each region.
