Empirical Study on Impact of Natural Disasters on Grain Production In China

摘要

Natural disaster is frequent and has a significant influence on the grain production in China.The paper analyzes the impact of the natural disasters and the grain sown area on grain production by using state space model.The research results show that the grain production will be increased by increasing the grain sown areas or improving anti-disaster ability.The arable land areas are limited in China,so our government must enhance the investment in the agricultural infrastructure construction,and improve the anti-disaster ability and reduce the influence on grain production from the natural disasters,in order to ensure the safety of grain production.
