农业机械化对农村环境影响的实证研究

为了分析农业机械化对农村生态环境的影响关系,研究采用1993-2012年的农业机械化总动力和农村环境综合评价指数进行了格兰杰因果检验。由分析结果可知:从短期看,农业机械化与农村环境之间没有显著的相互影响关系;但从长期来看,农业机械化与农村环境相互存在显著的影响。目前,我国正处于农业机械化对农村环境产生影响的关键时期,今后必须改善农业机械化粗放的发展策略,大大推进节能型和低碳型农业机械的研发。

An Empirical Research on Impacts of Agricultural Mechanization to Rural Environment

In order to explore the relation between agriculture mechanization and rural ecological environment in China , the article selected the total power of agricultural machinery and the index of comprehensive evaluation on temporal change of rural ecological environment in 1993-2012 to make the granger causal relation test .The results show that:firstly , there is little interactional relationship between agriculture mechanization and rural ecological environment in the short run;secondly , there is significant influence concern between agriculture mechanization and rural ecological environ -ment in the long run;thirdly , it is suggested the government should improve the extensive development strategy of agricultural mechanization in the future , and greatly promote the energy-saving and low carbon agricultural mechanization , since China is now in the critical period when agricultural mechanization has an significant impact on rural environment .
