基于投入产出模型的内蒙古水资源利用效益评价与分析

Evaluation and Analysis of Water Resources Utilization Efficiency in Inner Mongolia Based on Input-Output Model

贯彻黄河流域生态保护与高质量发展战略、落实“四水四定”发展理念、合理进行区域水资源配置是当前我国水资源管理的重中之重。利用投入产出模型分别分析并对比了内蒙古2012、2017年各部门的用水效率、用水效益、部门关联性及部门间虚拟水的转移量的实际状况。结果表明,各部门完全用水系数总体呈下降趋势;农业部门产出乘数最高为自治区基础产业;建筑业等工业部门的影响力系数不断增大,对其他部门经济拉动力不断增强,可见主导产业仍为工业;内蒙古虚拟水流向主要为农业到制造业和建筑业,制造业到其他行业,农业部门是最大的虚拟水净输出部门及虚拟水流出源头。研究成果可以分析“十三五”以来内蒙古节水型社会建设成效以及为“十四五”以后水资源配置利用规划提供参考依据。

Implementing the strategy of ecological protection and high-quality development of the Yellow River Basin,realizing the development concept of"Four Waters,Four Definitions",and rationally allocating regional water resources are the top priorities of China's current water resources management.The input-output model paper was used analyze the actual status of water use efficiency,water use effectiveness,sectoral correlation,and inter-sectoral virtual water transfers of each sector in Inner Mongolia in 2012 and 2017,respectively.The results show that the coefficient of complete water use in all sectors is generally on a downward trend;The highest output multiplier in the agricultural sector is the basic industry of the autonomous region;The influence coefficient of the construction industry and other industrial sectors has been increasing,and the pulling power of the economy of the other sectors has been increasing,so it can be seen that the dominant industry is still the industrial sector;The direction of the virtual water flow in Inner Mongolia is mainly from the agriculture to the manufacturing industry and the construction industry,and from the manufacturing industry to the other industries;The agricultural sector is the largest virtual water net output sector and the source of virtual water outflow.The research results can analyze the effectiveness of the construction of a water-saving society in Inner Mongolia since the"13th Five-Year Plan"and provide a reference basis for water resources allocation and utilization planning after the"14th Five-Year Plan".
