农业机械化、能源消费与经济增长耦合关系研究

农业机械水平一定程度上代表了农业现代化程度,能源作为驱动经济增长的原始物质动力至关重要。本文应用中国1980-2012年的相关数据,基于脱钩理论建立农业机械化、能源消费和农业经济增长之间的脱钩模型,对三者相互脱钩程度进行了详细评价。研究发现:农业机械化和能源消费之间的耦合程度并不高,多数年份处于弱脱钩和强脱钩状态;能源消费和农业经济增长之间的耦合程度较高,多数年份都处于扩张负脱钩状态,表现出农业经济增长对能源较强的依赖关系;农业机械化和农业经济增长之间的耦合关系最强,80%以上的样本数据都表现出扩张负脱钩状态,但脱钩指数绝大多数年份都较高,这也说明我国农业机械化对农业经济增长的拉动效率有待提升。

Linking between Agricultural Mechanization,Energy Consumption and Economic Growth

The level of agricultural machinery represents the degree of agricultural modernization to some extent. Energy is very crucial to economy growth which as a drive of raw material. The paper has established the model of decoupling be-tween agricultural mechanization, energy consumption and agricultural economic growth based on the decoupling theory and has carried on the detailed evaluation on the degree of mutually decoupling in the relative data of China from 1980 to 2012 . Research found that the coupling degree between agricultural mechanization and the energy consumption is not high and most of the years are in the weak decoupling and strong decoupling state. The coupling degree of energy consumption and agricultural economic growth is higher and most of the years are in the expansion negative decoupling state which shows the agriculture economy growth strongly depend on energy. The coupling relationship between agricultural mechani-zation and agricultural economic growth is strongest. More than 80% of the sample data is in negative decoupling state ex-pansion. But the decoupling index is higher in the vast majority of the year which suggests that the efficiency of China's agricultural mechanization driving agriculture economic growth need to be improved.
