水资源短缺已成为制约我国经济可持续发展的重要因素之一。科学的合理的投资水利工程才能有效地改变我国水资源的分配状况,促进经济可持续发展。文章以长江流域为例,主要通过运用长江流域1994年到2002年各省水利投资的数据,建立GDP与水利投资效益的计量经济模型。通过对水利投资经验数据回归分析,得出水利投资量符合经济增长要求。结果与我国目前财政状况与水利投资实际需要较为一致。
The shortage of water resources has become one of the important factors restricting the sustainable development of our economy. Science and reasonable investment in water conservancy projects can effectively change the distribution of water resources in our country and promote sustainable economic development. Taking Yangtze River Basin as an example, this essay establishes the econometric model of GDP and investment benefit of water conservancy mainly by using the data of water conservancy investment in various provinces in the Yangtze River Basin from 1994 to 2002. Through regression analysis of water conservancy investment experience data, it is concluded that the investment amount of water conservancy meets the requirements of economic growth. The results are in line with the actual needs of China’s current fiscal situation and investment in water conservancy.
