STUDIES ON THE SPATIAL DISTRIBUTION CHANGING OF CHINA'S RICE PRODUCTION AND ITS INFLUENCING FACTORS
运用区域重心法和空间面板模型，分析了1978年以来中国水稻生产重心从南向北移动的轨迹，发现农业劳动力、化肥、单产、有效灌溉面积和耕地面积有正向影响，农村非农就业机会有负向影响。
The paper firstly uses regional gravity center method to describe the spatial evolvement track of rice production gravity center in China since the year 1978,and then investigates the causes of the regional changes in the rice production by using spatial panel model.The empirical results show that : there is an obvious regional correlation in China's rice production;the rice production in China is moving from south to north.The spatial distribution changing of it is affected positively by the number of agricultural labor,the agricultural chemical fertilizer,the rice yield per unit,the effective irrigation area and cultivated area,and affected negatively by the rural people's non-agricultural employment opportunities.
