赤眼蜂防治玉米螟技术采用影响因素分析——兼论技术特性对技术采用的影响

Analysis on Influencing Factors of Technical Adoption of Trichogramma to Control Ostriniae——Also On Impact of Technical Characteristics to Technical Adoption

基于吉林调研农户数据,采用多个Logit模型比较分析赤眼蜂防治玉米螟技术采用的影响因素,研究发现,赤眼蜂防治玉米螟的技术特性决定了该技术的采用不仅与微观农户技术需求有关,也与技术供给有关,实证也验证了农业技术供给和玉米种植规模对农户技术采用有显著的正向影响。样本数据反映,如此经济、环保又增产的农业技术并未能在我国得到广泛应用,与我国农技推广力度严重不足密切相关。从符合WTO规则及更好地实现我国粮食安全角度来看,我国应加大粮食主产区的农技推广力度。

Based on the survey data of Jilin farmers, this research used four Logit models to compare and analyze the influencing factors of adoption of the technology of trichogramma to control ostriniae. Studies suggest that technical characteristics determine that the technical adoption relates not only to farmer＇s micro technology needs, but also to technology supply. The empirical results verify that the agricultural technology supply and maize planting scale has a significant positive impact on technology adoption by farmer. The sample data show that the agricultural technology that is economic and environmental friendly and can increase production is not widely used in China, that is related to the severe shortage of agricultural technology extension and service in China. From the perspective of realization of food security in China and compliance with WTO rules, China should increase the promotion of agricultural technology in the major grain producing areas.
