河南省农业旱涝防灾动态效率及其分解

The Dynamic Efficiency and its Decomposition of Agricultural Drought and Flood Disaster Prevention in Henan Province

运用DEA-Malmquist指数模型,测算了2005-2014年河南省农业旱涝防灾的动态效率及其分解情况。2005-2014年河南省农业旱涝防灾动态效率(Malmquist指数)平均为0.986,农业旱涝防灾动态效率总体呈现下降趋势,技术变化指数较低是导致动态效率值低下的主要原因。所有区域都面临技术变化指数下降的问题,为此,需要优化农业旱涝防灾投入结构,推进农业防灾技术革新,稳定各地区农业旱涝防灾投入份额,加强农业旱涝防灾配套制度,从而提升农业旱涝防灾的动态效率。

Using the DEA-Malmquist index model, we calculate the dynamic efficiency and its changes of agricuhural drought and flood disaster prevention of Henan Province in 2005 -2014. The average dynamic efficiency （ Malmquist index） of Henan agricultural drought disaster prevention is 0. 986 during 2005 - 2014. The dynamic efficiency of agricultural drought and flood disaster prevention shows an overall downward trend. Low technical change index is the main reason for low dynamic efficiency. All areas are faced with the decreasing technical change index. Therefore, we need to optimize the investment structure of agricultural drought disaster prevention, promote technological innovation of agricultural disaster prevention, stabilize investment share of agricultural drought disaster prevention in different region strengthen the supporting systems of agricultural drought disaster pre- vention, so as to enhance the dynamic efficiency of agricultural drought disaster prevention.
