利用省际面板数据，从全国及区域层面研究新增水利投资、各类型水利设施在抗击农业旱灾、水灾中的效果。研究发现：从全国层面看，新增水利投资能有效降低旱灾成灾率、水灾成灾率，但水利投资抗旱效果比抗击水灾效果好。水库能有效抗旱，但加重了水灾成灾率，水闸抗旱效果明显。从区域层面看，东、中、西部地区水利投资抗旱效果都较明显，而水利投资抗御水灾效果东部地区最明显。机井在中部地区对抗旱起到了一定作用，但东部、西部地区机井数量却与旱灾成灾率正相关。水闸抗御水灾的作用在中部地区显著。中部地区堤防长度与水灾成灾率正相关，西部地区机电排灌站装机容量与旱灾成灾率正相关。东...

Based on China' s inter-provincial panel data,the paper evaluates the agricultural drought and flood resisting effect of the newly increased water conservancy investment and various types of water conservancy facilities at national and regional levels. Research results show that the newly increased water conservancy investment can effectively reduce drought and flood disaster rate. However,the drought resisting effect of water conservancy investment is better than flood resisting effect. Reservoirs can effectively reduce drought disaster rate,but increase the rate of the flood disaster. And th...
