河南省农业信息化对农村经济增长的影响

The Impacts of Agricultural Informatization on Rural Economic Growth in Henan Province

农业信息化是农业现代化的制高点,对农村经济增长具有重要影响。采用主成分分析、协整检验和Granger因果分析等方法,探究了河南省农业信息化对农村经济增长的影响。结果显示,农业信息化基础设施对农业信息化的贡献率最大,为51.741%;其次是农业信息化投入水平,贡献率为36.829%。河南省农业信息化和农业总产值之间存在长期均衡关系,农业信息化基础设施、农业信息化投入水平对农村经济增长呈正向推动作用。农业信息化基础设施是河南省农业总产值的Granger原因,但农业总产值不是农业信息化基础设施的Granger原因;农业信息化投入与农业总产值互为Granger原因的关系不明显。

Agricultural informatization is the commanding height of the modernization of agriculture and has an important impact on rural economic growth. The paper used the methods including principal component analysis, cointegration test and Granger causality to analyze the impact in Henan province. The results showed that the agricultural informatization infrastructure contributed the most to the informatization of agriculture, of which the contribution rate was 51. 741%,followed by the agricultural informatization investment, of which the contribution rate was 36. 829%. There was a long-term equilibrium relationship between the level of agricultural informatization and total agricultural output in Henan province. The agricultural informatization infrastructure and agricultural informatization input had obvious positive effect on rural economy growth in Henan province. The agricultural informationization infrastructure was the Granger cause of Henan＇ s total agricultural output value, but the agricultural output value was not the Granger cause of the agricultural informationization infrastructure;the relationship between agricultural information input and agricultural output value was not obvious for each other.
