摘要
This article analyzed the influence of increasing wages on cropping patterns from theoretical and empirical perspectives.The results showed that the increasing labor cost provided a significant incentive to adjust the grain cropping pattern,which increased the production of the three major cereal grains but reduced the production of other grain crops.Increasing wages had a significant negative impact on cash crops.More laborintensive cash crops experienced a larger negative impact in the context of increasing wages.The increase in labor costs also had a negative impact on the proportion of vegetables produced,which was more evident in northern China.A further mechanism test indicated that factor substitution was a significant reason for cropping pattern changes;this illustrated the substitution of labor by machinery not only between grain crops and cash crops but also among different cash crops.
