【摘要】 运用中部地区湖南14个地州市面板数据所做的经验研究表明,人口城镇化与经济城镇化对提高人均粮食播种面积与人均粮食产量均有着较为显著的正向效应,经济城镇化效应相对更为明显,二者当前均有利于保障粮食安全。提高粮食单产水平,在能显著提升人均粮食产量的同时,对人均粮食播种面积起着负向作用。为此,需加大种粮专业人才队伍建设,提升粮食单产水平,加快土地流转速度,为粮食生产的规模化与机械化创造条件,以减少城镇化对粮食生产所带来的不利影响。更多还原

【Abstract】 The empirical research based on the panel data of 14 prefectures and municipalities in Hunan Province shows that population urbanization and economic urbanization are of the significant negative positive on per capita grain sowing area and per capita grain yield. The effect of economic urbanization is relatively more obvious. Although it improves the level of per unit grain yield in energy by significantly increasing the per capita grain output, it also plays a negative role in the per capita grain planting area. Therefore, it is necessary to strengthen the construction of grain-growing professionals, to raise the level of grain yield per unit area, to speed up the speed of land flow, and to create conditions for the scale and mechanization of grain production, so as to reduce the adverse effects of urbanization on grain production.更多还原
