【摘要】：水資源短缺為掣肘安徽省經(jīng)濟(jì)社會(huì)可持續(xù)發(fā)展約束因素之一,提高水資源利用效率是破解其關(guān)鍵。運(yùn)用完全分解模型,就技術(shù)進(jìn)步、結(jié)構(gòu)變動(dòng)因素對(duì)安徽省單位GDP水耗貢獻(xiàn)份額進(jìn)行了測(cè)度,結(jié)果表明:(1)2001~2014年,技術(shù)進(jìn)步導(dǎo)致安徽省單位GDP用水年均下降31.91m3,是提高水資源利用效率關(guān)鍵因素,貢獻(xiàn)率高達(dá)88.69%,三次產(chǎn)業(yè)技術(shù)進(jìn)步貢獻(xiàn)率分別為45.19%、38.59%、4.91%;(2)產(chǎn)業(yè)結(jié)構(gòu)調(diào)整對(duì)安徽省單位GDP用水強(qiáng)度下降貢獻(xiàn)率為11.31%,三次產(chǎn)業(yè)變動(dòng)貢獻(xiàn)率分別為-4.98%、0.62%、15.66%。提高安徽省水資源利用效率核心在于:依靠科技創(chuàng)新,促進(jìn)一、二產(chǎn)業(yè)技術(shù)水平提升,調(diào)整、優(yōu)化產(chǎn)業(yè)結(jié)構(gòu),大力提高第三產(chǎn)業(yè)比重。研究結(jié)果,可為安徽省制定水資源利用效率的政策提供決策參考。
[Abstract]:The shortage of water resources is one of the constraints to the sustainable economic and social development of Anhui Province, and improving the efficiency of water resources utilization is the key to solve the problem. The structural variation factors have measured the contribution share of water consumption per unit GDP in Anhui Province. The results show that the technological progress resulted in an average annual decrease of 31.91m3 per unit GDP water use in Anhui Province from 2001 to 2014, which is the key factor to improve the water resources utilization efficiency. The contribution rate of industrial structure adjustment to the decrease of water use intensity per unit of GDP in Anhui Province is 11.31, and the contribution rate of the third industry change is -4.98 to 0.62and 15.66.The contribution rate of industrial structure adjustment to the unit GDP water use intensity of Anhui Province is -4.98 and 0.620.660.The contribution rate of industrial structure adjustment to the unit GDP water use intensity of Anhui Province is 11.31, and the contribution rate of the third industry change is -4.98 and 0.620.62 respectively. The efficiency of water resources utilization in Anhui Province is improved. The core is: relying on scientific and technological innovation, To promote the technical level of the first and second industries, to adjust and optimize the industrial structure, and to increase the proportion of the tertiary industry. The results of the study can provide a decision reference for the formulation of water resources utilization efficiency policy in Anhui Province.
