Since 2011,Pudong New Area in Shanghai has implemented a series of subsidy policies for increasing farmers' incomes. To examine the effects of these policies,this paper draws on the DEA-Malmquist Model,based on the input and output data of each town in Pudong New Area in 2011 ~ 2016,to measure and analyze the overall technical efficiency and total factor productivity of these policies. The result shows that if Pudong New Area is taken as single administrative unit and the overall technical efficiency is set at 1,the total factor productivity goes downward first and then upward. It also shows that DEAs are effective in most towns but there is a regional difference in total factor productivity. It concluded that( 1) the subsidy policies in Pudong New Area for the increase of farmers' incomes had achieved remarkable results as a whole;( 2) the policies showed a diminishing marginal functional effect with an L shape of total factor productivity from 2011 to 2016;( 3) there was a regional difference in total factor productivity among different towns,towns in the north being better than those in the south. Based on the conclusions,this paper suggested Pudong government should keep subsidy policies consistent and stable,adjust the structures of the subsidies,and increase subsidies to the southern towns.
