摘要
通过建立动态乘数分析模型,结合历年广东省水利投资额、GDP各项分类数据,采用回归分析的方式,计算广东省水利投资的动态投资乘数,并以此定量分析广东省历年水利投资对国民经济的贡献率。结果表明,2000—2017年间,广东省水利投资的动态投资乘数为2.57,广东省水利投资对GDP的贡献率为0.65%～2.40%。
The investment multiplier model was established through regression analysis of the water conservancy investment data and GDP data over years to calculate the investment multiplier in Guangdong Province.Furthermore,the contribution rate of water conservancy investment to national economy growth was analyzed quantitatively by the calculation results.The results showed that the investment multiplier was 2.57,and the contribution rate of water conservancy investment to national economy in Guangdong Province was between0.65%~2.40%during the year of 2001~2017.
