中部地区水资源利用与经济社会发展关系研究

Research on the Relationship between Water Resources Utilization and Economic and Social Development in Central China

  • 摘要: 中部地区是我国重要的经济枢纽,但"中部塌陷"问题使其可持续发展动力不足。为探究高质量发展背景下该地区资源与社会经济发展的关系,本研究以五大发展理念为基准层构建绿色发展指数,运用SBM模型评估了2003-2018年中部地区水资源利用效率,并利用Tapio脱钩模型探究不同阶段中部地区社会经济发展与水资源的关系。研究表明:中部地区水足迹年际波动明显,在2015年达到最大值6 835.4亿m3;各省绿色发展指数整体呈现稳步上升态势,且在2008年空间差异性最小;中部地区水资源利用效率均值在2006年达到峰值,山西和湖北达到效率最优;水资源与经济社会发展的脱钩关系随时间变化逐渐好转,说明中部地区水资源利用逐渐满足国家高质量发展的要求。该研究可为中部地区水资源利用和经济社会高质量发展提供参考。

     

    Abstract: The central region is an important economic hub in our country,but the problem of“central collapse”makes its sustainable development lack of power. In order to explore the relationship between resources and social and economic development in the context of highquality development,this paper takes the five development concepts as the baseline layer to construct the green development index,which is taken as the expected output,and uses the SBM model to calculate the water resource utilization efficiency in the central region from 2003 to2018. Finally,the Tapio decoupling model is used to explore the relationship between social and economic development and water resources in central China at different stages. The results show that the interannual fluctuation of water footprint in the central region is obvious,reaching the maximum value of 683.54 billion m3 in 2015. The green development index of all provinces showed a steady upward trend,and the spatial difference was the least in 2008. The mean value of water resource utilization efficiency in the central region reached the peak in2006,and Shanxi and Hubei reached the highest value. The decoupling relationship between water resources and economic and social development gradually improved over time,indicating that water resources utilization in central China gradually met the requirements of highquality development of the country. This paper has certain guiding significance for the high quality development of the central region.
