In order to explore the economic effect of organic fertilizer application,the cost efficiency of organic fertilizer application in different scale farms was evaluated scientifically.Based on the survey data of 489 apple growers in Shandong Province,we analyzed and evaluated the production efficiency and economic effect of organic fertilizer application by apple growers by using PSM model and new cost efficiency model.The results showed that:firstly,compared with the control that without organic fertilizer application,the application of organic fertilizer increased the production technical efficiency,labor productivity,land productivity and net profit per unit of land by 4.8％,1111.53kg/person,6786.14kg/hectare and 22,800 yuan/hectare,respectively,on average.Secondly,by comparing the new cost efficiency of farmers with different scales,it was found that the production efficiency of farmers with a planting scale of 0.267～0.533 hectares was relatively higher,and there was an"inverted U-shaped"trend between planting scale and production efficiency.Thirdly,continuous application of organic fertilizer was beneficial to restrain the ineffective loss of input technology and promote the cost saving and efficiency increase of high value perennial agricultural products such as apple.Therefore,it is suggested that the government and other relevant departments should increase the intensity of information intervention,strengthen professional technical training,optimize the allocation of factor input to improve the level of organic fertilizer application,and promote the green development of agriculture.
