The impact of climate change on crop productivity is a hot research topic in agricultural production,and indirect crop simulation models have been evaluated by many researchers.During the years of 1992 to 2012,the apple yield in 8 main producing provinces of China was significantly influenced by the climate change factor,which was indicated by temperature,precipitation and sunshine hours.In this paper,the impacts and contribution of climate change on apple productivity were explored by using stochastic frontier trans-log function with a panel data set from the 8 provinces.The empirical results showed that the apple yield potential increases about 2.38%-2.89%induced by raising per 1℃in temperature factor,decreases about 2.07%-5.43%induced by raising per 10 mm in precipitation factor,and decreases about 1.01%-1.33%induced by raising per 10 hin sunshine hours factor;secondly,the climate factors affect apple yields through interaction with area,the precipitation and sunshine hours have negative effects on the yield,and the temperature has positive effects on the yield;thirdly,the major contributor to the apple yield growth is TFP growth which accounts for 32.98% of apple production growth in the period of 19922012,the average contribution sourced from the input growth is 21%,whereas the climate has a negative contribution at the level of-13.6%.
