    摘要:

    利用松弛变量度量(slack based measure,SBM)的超效率模型,对污染排放约束下中国2004—2014年23个水稻生产省(市、自治区)的水稻生产用水效率进行测度分析,并通过Tobit模型分析影响水稻生产用水效率的因素。结果表明:在污染排放约束下很多地区的水稻用水效率没有达到生产的前沿面,各地区的水稻生产用水效率存在很大差异,总体上各地区的水稻用水效率呈不断提升的趋势。从水稻生产区域来看,长江中下游地区的水稻生产用水效率最高,而华北地区的水稻生产用水效率多年来一直最低,东北地区和西南地区的水稻生产用水效率的年度波动幅度较大。农村居民人均纯收入、水稻播种面积占比和水稻机械化水平对水稻生产用水效率有显著的正向影响,而水资源丰裕程度、农田水利设施和节水农业发展水平对水稻用水效率并没有显著影响。

    Abstract:

    Using the slack based measure(SBM)super based measure, the rice production water use efficiency in 23 provinces from 2004 to 2014 was analyzed and its influencing factors was discussed by Tobit model. The results showed that the production water use efficiency in many provinces under the constraint of pollution emission did not reach the production frontier. The rice production water use efficiency in different regions varied greatly and showed a rising trend. The rice production water use efficiency in the middle and lower reaches of the Yangtze River was the highest, which was the lowest in North China for many years. The annual rice production water use efficiency in the northeast and southwest regions fluctuated greatly. The per capital net income of rural residents, proportion of rice sown area, and rice mechanization level had a significant positive effect on the rice production water use efficiency. And the water resources abundance, farmland water conservancy facilities and water-saving agriculture development level had no significant effect on the rice production water use efficiency.
