摘要
农地规模经营绩效的实现与生产者的经营能力息息相关,而农业技术培训是提高经营能力的重要政策工具。因此,将技术培训纳入到经营规模与收入关系的探讨中统一考察,有助于更好把握规模经营主体的收入增长规律。利用江苏省360个粮食类家庭农场调研数据,采用多元回归方法,从单位面积纯收益的维度分析了经营规模、农业技术培训对农场收入的影响,并检验了技术培训所发挥的调节效应。结果表明:经营规模与收益之间呈倒“U”型关系,在6.67~13.33 hm^2区间内纯收益最高,并计算得出样本农场最优规模为8.5 hm^2,在未达到最优规模之前,经营规模每增加1 hm^2将使得收益增加1.7%,超过该规模后收益随着规模的增加而减少;技术培训对农场收益具有显著的正向影响,影响系数为0.031。另外,农业技术培训能够改善农场生产者经营能力与规模的匹配度,对经营规模与收益之间的关系具有正向调节作用。因此,提出加强农地流转市场建设,发挥适度规模效应;培育家庭农场等规模主体要与主体农业技术培训,经营能力提升相结合的政策建议。
Management performance is closely related to farmers’management capability;while agricultural technical training is an important policy tool to improve the management capacity of farmers.Therefore,the integration of technical training into the analytical framework of the relationship between farm operation scale and farm income will help to grasp the income growth mechanism of scale economics in farming.Based on a survey data of 360 family grain farms in Jiangsu,this paper investigates the relationship among farm operation scale,agricultural technical training,and farm income from the perspective of net income per unit area,and tests the mediation effect of technical training.Results show that the relationship between farm operation scale and farm income is an inverted“U”shape:the highest net income per hectare is in the 6.67~13.33 hm^2 scale range.Calculation shows that the optimal scale of the sample farm is 8.5 hm^2,and before the optimal scale,each additional hectare of farm operation will improve income by 1.7%.Agricultural technical training has a significant impact on farm income with influence coefficient of 0.031.At the same time,agricultural technical training also has a positive mediation effect on the relationship between farm operation scale and farm income.Therefore,this paper suggests that the government should strengthen the construction of farmland circulation market to realize moderate scale effect.Meanwhile,cultivating family farms with proper operation scale should be combined with agricultural technical training.
