契约农业对家庭农场采纳环境友好型技术的影响

On the impact of contract farming on family farms’adoption of environmentally friendly technologies

【目的】为测土配方施肥技术的推广提供决策依据。【方法】基于全国1706个种植业家庭农场调查数据,借助Probit模型和倾向得分匹配(PSM)方法实证检验契约农业对家庭农场采纳测土配方施肥技术的影响。【结果】Probit模型结果表明:家庭农场参与契约农业对其采纳测土配方施肥技术具有显著的正向影响,影响系数为0.621;PSM模型结果表明:与未参与契约农业的家庭农场相比,参与契约农业的家庭农场平均处理效应为0.19,技术培训、农场主从事农业规模经营年限、农场主的从业经历、家庭农场具有规范的日常收支记录以及未来扩张意愿对技术采纳也有影响。【结论】契约农业是影响家庭农场采纳测土配方施肥技术的重要因素,政府应进一步加快建立健全契约农业参与机制,支持家庭农场提升资源禀赋水平。图2表3参18。

[Object]It is expected to provide decision-making basis for the promotion of soil testing and formula fertilization technology.[Method]With 1706 family plantations selected as the subjects,this paper,after an investigation of the influence of contract farming on the adoption of soil testing and formula fertilization technology on family farms by means of Probit and propensity score matching(PSM),is aimed to provide decision-making basis for the promotion of such environmentally friendly technologies.[Result]The participation of family farms in contract farming has a prominent and effective influence on the adoption of soil testing and formula fertilization technology with an influence coefficient of 0.621.The average treatment effect is about 0.19 and the adoption of such environmentally friendly technologies is also significantly subject to elements like farmers’participation in soil and fertilizer cultivation technology training,the duration of largescale agricultural operations,farmers’experience,farms’daily records of income and expenditure and farms’intention for future land expansion.[Conclusion]Contract farming is a vital factor affecting the adoption of soil testing and formula fertilization technology by family farms,therefore,efforts are called from the government to further accelerate the establishment of a sound participation mechanism of contract farming and support family farms in the promotion of their resource endowment.[Ch,2 fig.3 tab.18 ref.]
