【摘要】：基于农业机械化的视角,本文通过构建面板固定效应模型,分析农业机械化对食物消费需求的影响,以期为中国农村居民食物消费之谜提供一种新的解释。研究表明:(1)随着农村居民收入水平的提高,我国农村居民人均食物消费量却呈不断下降趋势,其中粮食消费量下降了28.85%,而猪肉消费仅增长了10.16%;(2)农业机械化对农民的食物消费有着显著的节约效应。耕种收综合机械化率每提高1个百分点,将促进居民总热量摄取降低0.19%,2000—2012年机械化发展带来的粮食节约效应约占农村居民粮食消费下降比重的17.45%;(3)农业机械化促进了食物消费结构的调整。粮食消费量下降作为食物消费结构变动的主因,2000—2012年机械化带来的粮食消费节约量约占总粮食消费量下降比重的11.96%。当前粮食仍作为居民热量摄取的主要来源,农业机械化通过"节流"降低粮食消费需求,能有效保障国家粮食安全。
[Abstract]:Based on the perspective of agricultural mechanization, this paper analyzes the impact of agricultural mechanization on food consumption demand by building a panel fixed effect model, in order to provide a new explanation for the mystery of food consumption of Chinese rural residents. The results show that: (1) with the increase of the income level of rural residents, the per capita food consumption of rural residents in China is decreasing. Among them, the grain consumption decreased 28.855.The pork consumption increased only 10.16. (2) Agricultural mechanization has a significant saving effect on farmers' food consumption. For every 1 percentage point increase in the rate of comprehensive mechanization of farming, The grain saving effect caused by mechanized development in 2000-2012 accounted for 17.45% of the decreasing proportion of rural residents' grain consumption. (3) Agricultural mechanization promoted the adjustment of food consumption structure. The decrease of grain consumption is the main reason for the change of food consumption structure. The grain consumption savings caused by mechanization in 2000-2012 accounted for 11.96% of the decrease in total grain consumption. At present, grain is still the main source of caloric intake of residents. Agricultural mechanization can effectively guarantee national food security by reducing grain consumption demand through "reducing expenditure".
