摘要
基于SBM模型测算2003—2016年中国省际水-能源-粮食综合利用效率,并结合ESDA方法对水-能源-粮食综合利用效率的空间相关性进行分析,最后利用SLM模型对中国水-能源-粮食综合利用效率的影响因素进行检验。结果表明,中国整体水-能源-粮食综合利用效率不高,且呈现下降趋势,各地区、各省市水-能源-粮食综合利用效率存在明显差异性,总体呈现出东部>东北>中部>西部的格局。中国水-能源-粮食综合利用效率存在显著的正向空间自相关,分布格局不够稳定,前期易发生波动,后期趋于稳定。水-能源-粮食综合利用效率的影响因素有技术进步、受教育程度、基础设施、经济集聚、经济发展水平和城市化。未来应尽快将水-能源-粮食问题上升到战略高度,对其发展进行顶层设计,各区域要建立跨区域的协调组织与相应协调机制,各省市则要结合自身实际情况制定有针对性的措施,并尽快推动经济由粗放式发展向绿色发展转变。
China’s consumption of water,energy and food resources ranks first in the world.How to ensure their utilization with high quality,high efficiency and low pollution has become a key issue in China’s sustainable development.Based on the SBM model,the inter-provincial water-energy-food(WEF)comprehensive utilization efficiency in China from 2003 to 2016 is estimated.The spatial correlation of WEF comprehensive utilization efficiency is analyzed by ESDA method.Finally,the influencing factors of WEF comprehensive utilization efficiency in China are tested by SLM model.The results show:(1)the overall WEF comprehensive utilization efficiency in China is not high,showing a downward trend.There are obvious differences in the comprehensive utilization efficiency of WEF among regions and provinces,with the overall pattern of WEF comprehensive utilization efficiency in eastern region>that in northeastern region>that in central region>that in western region.(2)There is a significant positive spatial autocorrelation in the comprehensive utilization efficiency of WEF in China,and the distribution pattern is not stable enough as it is easy to fluctuate in the early stage and tends to be stable in the later stage.(3)The influencing factors of WEF comprehensive utilization efficiency include technological progress,education level,infrastructure,economic agglomeration,economic development level and urbanization.Finally,some suggestions are put forward,including top-level design,optimization of industrial layout,protection of cultivated lands,promotion of national cultural level,and promotion of technological progress.
