中国农业机械化发展对粮食播种面积的影响

The Impact of Agricultural Mechanization on Structure Adjustment of Grain in China

本文利用农村固定观察点的农户调查数据,研究了中国农业机械化发展对农户粮食播种面积的影响。研究结果表明:农户在粮食生产过程中是否使用农业机械化服务,对粮食播种面积都不会有显著影响;但是,不断上涨的每亩农业机械作业费用会降低农户粮食作物播种面积及其在农作物总播种面积中的占比;如果农户地处平原地区,每亩农业机械作业费用上涨对该类农户粮食播种面积及其占比的负向影响将会被削弱。

This article examines the impact of the rapid development of agricultural mechanization in China on the sown area of grain.The study focuses on two questions,namely,whether the use of agricultural mechanization services affects the grain production structure,and whether the unit cost of mechanization services affects the grain production structure.It finds that the use of agricultural mechanization services has no significant impact on the grain production structure adjustment,but the rising unit cost of mechanization services has a positive impact on the structure adjustment.In addition,for households located in plain areas,the rising unit cost of mechanization services is found to weaken the negative impact of mechanization on the structure adjustment.
