RESEARCH ON THE EVALUATION AND PROMOTION OF AGRICULTURAL WATER USE EFFICIENCY IN SHANDONG PROVINCE
In order to scientifically evaluate the agricultural water use efficiency of Shandong Province,DEA-BCC-I model was used to calculate the agricultural water use efficiency of Shandong Province,and Malmquist index was used to study the dynamic evolution mechanism of water use efficiency of 16 prefecture level cities in Shandong Province from 2011-2021.The research results indicate that the comprehensive efficiency value of agricultural water use in Shandong Province in 2021 is 0.822,which is relatively high over-all;The order of agricultural water use efficiency from high to low is:Central Shandong>East Shandong>Southwest Shandong>Northwest Shandong;From 2011 to 2021,the total factor productivity of agricultural water use in Shandong Province showed an upward trend,but the comprehensive efficiency of water use showed a downward trend;Technological progress is the main driving force for the improve-ment of total factor productivity of water use in Shandong Province;It is recommended to take measures such as technological innova-tion,promoting balanced development among different regions,improving the matching degree of investment factors,reasonably control-ling investment scale,and regulating water resource prices to improve agricultural water use efficiency in Shandong Province.
