农户甘蔗种植机械化的因素解析：诱因及交互效应
Analysis of Sugarcane Planting Mechanization Factors and Its Interactive Effects

甘蔗是中国食糖的主要原料，近10年甘蔗糖占全国食糖产量的90%以上。我国甘蔗种植机械化率约为6%，较低的种植机械化水平直接影响到甘蔗产业的综合效益和现代农业的发展。本文利用农户微观调查数据研究了影响农户采用机械种植甘蔗的因素，并着重分析土地因素及其交互项的作用。研究发现，总体土地质量、受教育年限、是否参加农机培训、农业劳动力所占比重、是否加入农机合作社、甘蔗专业化程度、甘蔗收入比重、是否平原、家庭人均收入以及地区哑变量对种植机械选择概率具有显著作用；同时是否租入土地、新植面积地块质量和农业劳动力人均新植面积具有正向作用；总体土地质量与某些因素具有交互效应，而土地因素之间具有难以替代的作用。
Sugarcane is the main raw materials in Chinese sugar, more than 90% of the sugar production comes from saccharose in recent 10 years. The rate of sugarcane planting mechanization is only 6%, the low mechanization level of sugarcane planting directly affects the sugarcane industry comprehensive benefits and the development of modern agriculture. Using a sample of households in rural China, this paper studies the factors that affect farmers adopting planter and emphatically analyzes the factors of land and its interaction term. This study found that the remarkable factors to planter selection probability are land quality, educational status, the training of agricultural machinery, the proportion of agricultural labor force, agricultural machinery cooperatives, the degree of sugarcane specialization, the income proportion of sugarcane, plain, average family income and regional dummy variables. At the same time, it has a positive effect on whether to rent the land, the land quality of cultivated area and the planting area per capita of agricultural labor force. Finally, there are interaction effects between land quality and certain factors, and it has irreplaceable role between land factors.
