Empirical analysis on input-output relationship of apple planting in China

Bssed on analyzing the benefits of apple planting in 1991-2014，the panel date in seven mainly provinces of apple planting were selected and an empirical analysis on the input-output efficiency of apple planting was carried out by DEA data envelopment model. The results showed that the cost and production value profit margins of apple planting declined since 2010，indicating that apple planting benefits were low recently. The empirical analysis showed that the input-output efficiency of apple was not high as a whole and technological progress was the key to improve efficiency. Therefore，it should improve the efficiency of apple planting by enhancing technical capacity.
