摘要：Various types of scale management have played a leading role in modern agriculture. Whether agri- cultural subsidies have scale effect has become an important theoretical and practical issue. Based oncost-benefit and elasticity theory, we analyzed the mechanism of agricultural subsidy policy on landscale management, and using panel data from 2000 to 2014, we find that: (1) Agricultural subsidy has a significant impact on farmers' scale management, themore agricultural subsidies, the more farmers' will. ingness to scale management. (2) The greater the in-come elasticity of demand for agricultural products, the greater the impact of agricultural subsidies on farmers' scale management. (3) The more farmers) non-agricultural income, the more unfavorable to the scale management of farmers, and it is more obvious in the main grain-producing areas. Based on these conclusions, some suggestions are put forward to op- timize the agricultural subsidy policy.
