【摘要】：本文基于2001—2013年我国水稻、小麦和玉米生产的面板数据,采用DEA-Malmquist指数方法测算谷物全要素生产率,分析谷物全要素生产率的动态演进特点,比较水稻、小麦和玉米全要素生产率的区域差异。研究表明,2001年以来我国谷物全要素生产率呈先增后减的态势,主要影响因素是技术变迁与经营规模;主产区谷物生产明显优于平衡区,主销区则以水稻生产为主,规模效率偏低,科技进步显著;水稻的全要素生产率较小麦和玉米相比更具有优势。推进科技创新,因地制宜实施农业科技政策,引导适度规模经营,培育新型农业经营主体,优化粮食功能分区,制定差异化农业发展政策是提高谷物生产效率,增强国家谷物供给能力的有效途径。
[Abstract]:Based on the panel data of rice, wheat and maize production in China from 2001 to 2013, the total factor productivity (TFP) of grain was measured by DEA-Malmquist index method, and the dynamic evolution characteristics of TFP were analyzed and compared. The regional differences of total factor productivity of wheat and maize show that the total factor productivity of cereals in China has increased first and then decreased since 2001, the main influencing factors are technological changes and management scale, grain production in main producing areas is obviously superior to that in balanced areas. The main marketing areas are mainly rice production, low scale efficiency and remarkable scientific and technological progress, and the total factor productivity of rice is more advantageous than that of wheat and corn, so as to promote scientific and technological innovation and implement agricultural science and technology policies according to local conditions. It is an effective way to improve grain production efficiency and strengthen national grain supply capacity to guide moderate scale management, cultivate new agricultural management main body, optimize grain function zoning, and formulate differential agricultural development policy.
