In recent years, the rapid development in Guangzhong region has brought enormous challenge to this region of poor water resources. Therefore, it is necessary to analyze the water efficiency of Guangzhong region.This article compared and analyzed the output value and water consumption index comprehensively for nearly a decade (2004-2013) by using disconnected analysis method and water consumption of output valued per 10 thousand yuan.The paper found that Guanzhong region's economic growth is rapid and water use efficiency has been consecutively improved, on the whole the economy of the region is better than that of the national average level, but there is still gaps compared with developed countries.The water efficiency in primary industry has been continuously improved,which has great influence on the whole; the secondary industry is improved significantly but the trend has become slow;the third industry is one with the least water consumption of output valued per 10 thousand yuan, but the index has showed a rising trend and appears the emergence of expanding multiple hook which should arouse vigilance.
