粮食最低收购价格与农民收入的相关性研究——以湖南省为例

Correlation between policy of minimum supporting price of grain and farmers' income:Set Hunan province as an example

以湖南省为例,根据1995—2010年的统计数据,建立回归模型对粮食最低收购价格与农民收入之间相关性进行实证分析,结果表明:粮食最低收购价格对农民收入具有重要影响,相关系数达0.8,影响系数为4.147 259,提高粮食最低收购价格可以有效地增加农民收入。在深入分析粮食最低收购价格政策实施中存在的主要问题的基础上,提出了完善粮食最低收购价格形成机制、拓宽粮食收购渠道、健全农业生产资料限价、农业补贴机制等政策建议。

Taking Hunan Province for example,a regression model based on the statistic data during 1995-2010 was established to analyze the correlation between minimum supporting price of grain and the farmers＇ income.The results indicate that their correlation coefficient is 0.8 and influence coefficient is 4.147259,which means the minimum supporting price of grain is very important to farmers＇ income,and farmers＇ income will be increased by raising the purchase price.After analyzing the problems existing in the process of grain price policy implementation,the author proposes that some measures should be taken： to perfect the food price formation mechanism,to expand the grain purchasing channels and to improve the agricultural subsidy system.
