【摘要】：在资源环境成为紧缺生产要素的今天,用水效率可以作为行业水平的重要评价指标之一。采用超对数随机前沿模型,对纺织业用水效率进行评价与分析,从生产函数出发选取固定资产净值年均余额、从业人员年均人数和纺织业年用水量3个指标作为投入,主营业务收入作为产出,评价我国31个省域2006年与2014年的纺织业用水效率;并采用分层聚类法,分析其效率类型。结果显示:31个省域中天津、黑龙江和贵州等8个省域的纺织业用水效率是下降的,而其他省域的效率是上升的;不同省域之间差异较大,其中北京、天津和河北等9个省域效率较高,吉林、辽宁和重庆等14个省域初期效率不高但增长较快,黑龙江、贵州和云南等8个省域效率较低。
[Abstract]:Water use efficiency can be regarded as one of the important evaluation indexes of industry level when resource and environment become scarce factors of production. Based on the super-logarithmic stochastic frontier model, this paper evaluates and analyzes the efficiency of water use in textile industry, and selects three indexes, namely, the average annual balance of net fixed assets, the average number of employees and the annual water consumption of textile industry, as input from the production function. The main business income is used as output to evaluate the water use efficiency of textile industry in 31 provinces of China in 2006 and 2014, and to analyze its efficiency types by stratified clustering method. The results show that the water use efficiency of textile industry in 31 provinces of Tianjin, Heilongjiang and Guizhou decreased, while that of other provinces increased. The efficiency of 9 provinces such as Tianjin and Hebei is high, the initial efficiency of 14 provinces of Jilin, Liaoning and Chongqing is low but the growth is fast, and the efficiency of 8 provinces such as Heilongjiang, Guizhou and Yunnan is low.
