地块特征对农业机械服务利用的影响分析——基于南方五省稻农的实证研究

Analysis of the Effect of Plot Characteristics on the Utilization of Agricultural Machinery: Based on the Rice Plots Data of South China

本文基于南方五省稻农地块的微观数据,利用固定效应模型分析了地块特征对稻农农业机械利用的影响。地块特征通过4个方面影响农户农机利用:地块零碎化、土壤质量、基础设施便利性、地块来源。研究表明,地块面积越大,稻农越容易采用农机作业。土壤质量越差,越不利于稻农采用农机进行收割。相对于其他因素,地块基础设施对稻农是否采用农业机械生产的影响最大。如果地块灌溉条件不好或机耕路不便使得机器难以抵达田间,则农户使用机器耕整和收割的概率分别下降13.1和41.6个百分点。如果地块是从市场租入,则农户采用农机作业的概率增加。

Based on data of rice farmer's plots in South China with five provinces,the paper analyzes the effect of plot characteristics on the utility of agricultural machinery using fixed effect model. The following four aspects are the probable channels of plot characteristics affecting the use of agricultural machinery by farmers: land fragmentation,soil quality,access to agricultural infrastructures,the ownership of plot. The results show that the bigger the plot area,the farmers are more likely to use machine to cultivate. The poorer the soil quality,the farmers use agricultural machinery to harvest with more unwillingness. Compared with other effects,the effect of road access is the largest. If the irrigation condition is not good or agricultural machine cannot reach the plot,the probability of farmers using machine to plow and harvest will reduce 13. 1% and 41. 6% respectively. If the plots are rented from other farmers,the farmers will more tend to use machine to cultivate. According to these results,the paper puts up some suggestions
