| 中文摘要: |
| 运用单位根检验、协整检验、格兰杰因果检验及多元回归分析，研究了水利投资、农田水利建设与农业经济增长之间的关系。研究表明，水利投资与农业经济增长之间存在长期协整关系，农业经济增长是水利投资的Granger原因，反之不成立。农田水利建设与农业经济增长之间存在长期协整关系，农田水利建设是农业经济增长的Granger原因，反之也不成立。通过建立农业经济增长模型，进行回归分析表明，农田有效灌溉面积和水土流失治理面积增加能够显著促进农村经济增长；而除涝面积变化不能显著影响农村经济增长。 |
| 英文摘要: |
| This paper studied the relationship among water conservancy investment, construction of water conservancy facilities and agricultural economic development through unit root test, co-integration test, Granger causality test and multivariate regression analysis. It demonstrated that there existed long -term co -integration relations between water conservancy investment and agricultural economic development, and between the construction of water conservancy facilities and agricultural economic development. It was provened that the agricultural economic development was the Granger cause of water conservang investment and the construction of water conservang facinties was the Ganger cause of agricultural economic development. The result of regression analysis based on the agricultural growth mode suggested that
increase of the effective irritation area and water and soil erosion area could notably promote agricultural economic development while waterlogging control had no effect on agriculture. |
