摘 要:基于2006—2019年山东省统计数据,对山东省的粮食安全、农业机械化与农业碳排放的现状进行分析,然后构建联立方程模型并利用最小二乘法进行检验,分析粮食安全、农业机械化与农业碳排放之间的关系。结果表明,提高农业机械化和降低碳排放有利于提高粮食安全,但农业机械化的推广应用与农业碳排放之间呈正相关关系,对碳排放量的约束会影响农业机械化的推广进而影响粮食产量。为了实现粮食安全和低碳经济的兼顾,提出从科技创新和数字化应用视角提高农业机械化率和单位面积粮食产量。Based on the statistical data of Shandong Province from 2006 to 2019,the current situation of food security,agricultural mechanization and agricultural carbon emission in Shandong Province was analyzed. Then a simultaneous equation model was constructed and the least square method was used to test,so as to analyze the relationship between food security,agricultural mechanization and agricultural carbon emission. The results showed that improving agricultural mechanization and reducing carbon emission were conducive to improving food security,however,there was a positive correlation between the popularization and application of agricultural mechanization and agricultural carbon emission. The restriction of carbon emission would affect the promotion of agricultural mechanization and then affect grain yield. In order to achieve the balance between food security and the low-carbon economy,it was proposed to improve the rate of agricultural mechanization and grain output per unit area from the perspective of scientific and technological innovation and digital application.
