- 为了测算农业技术培训对农户甜瓜生产效率的贡献程度，基于新疆甜瓜产业技术体系的农户调查数据，考虑到农户参加技术培训及培训频率产生的样本自选择和内生性问题，运用倾向得分匹配法的平均处置效应模型，实证研究农业技术培训及频率对农户土地生产率、劳动生产率、技术效率的贡献。结果表明：新疆甜瓜生产属于劳动密集型产业，现行的农业技术培训偏向于资本节约型；农业技术培训显著提高了农户土地生产率和技术效率，贡献率分别为20.869%、8.892%，技术培训频率对农户技术效率和技术效率贡献率分别为20.616%、11.518%，说明技术培训频率可进一步提高农户生产效率，农业技术培训及频率对劳动生产率贡献不显著；忽视农户参加技术培训及频率的选择性偏差和内生性问题，农业技术培训对农户生产效率的贡献将会被高估。
- Abstract:
- In order to explore the contribution of agricultural technology training to farmers′ production efficiency,based on survey data of melon production in Xinjiang,taking account of the sample self-selectivity and endogeneity of farmer participation in technical training,the propensity score matching mathod was used to study the contribution of agricultural technical training and frequency of participation on output performance and technical efficiency of households.The results showed that the production of melon in Xinjiang was labor-intensive,the current agricultural technology training preferred to be capital-saving.The agricultural technology training significantly improved the land productivity and technical efficiency of farmers,with the contribution rates of 20.869% and 8.892% respectively,the contribution rates of technical efficiency frequency were 20.616% and 11.518% respectively,indicating that the frequency of technical training further increased the production efficiency of farmers,while the contribution to labor productivity was insignificant.The neglect of farmers′ participation in technical training and frequency selective and endogenous problems,the contribution rates would be overestimated.
