南方沿海发达地区农业机械化贡献率分析

Analysis on Contribution Ratio of Agricultural Mechanization in Developed Southern Coastal Areas of China

从宏观经济量增量的角度 ,测算了农业机械化对农村经济不同方面的贡献率大小。结果表明 :在现阶段、机械化对农业产出增长的贡献大于劳动力 ,但小于农业物耗和农业用地 ;在 5个发达地区中 ,机械化对农村经济增长的贡献率大小 ,依次是江苏 >浙江 >广东 >福建 >上海。随着农村经济发展 ,农业机械化对农村经济增长的贡献 ,会经历一个由小变大、再从大变小的过程。农村经济高度发展时 ,贡献率虽然变小 。

The contributing ratios of agricultural mechanization to varied aspects of rural economy were calculated at an angle of macroeconomic increments.The results showed that at the present stage the machanization's contribution to agrictultural output growth was greater than the labor's but less than material consumption's and agricultural land's and that the descending order of the mechanization's contribution to rural economic growth for the five developed regions was Jiangsu>Zhejiang>Guangdong>Fujian>Shanghai.The mechanization's contribution to rural economic growth would go through a process of becoming greater and then returning to smaller with development of rural economy.When rural economy highly developed the contribution would become smaller but agricultural production would depend on the mechanization more deeply.
