摘要:

为了解中国小麦种植户生产性服务外包对测土配方施肥技术采纳的影响，运用7个粮食主产区826户微观数据，通过内生转换概率模型(ESP)讨论了农户将生产服务外包时对其测土配方施肥技术采纳的影响。结果表明:1)生产性服务外包对测土配方施肥技术采纳有显著正向影响，且农户具有减量施肥需求会更倾向于将服务外包；2)随着服务外包程度的提升，测土配方施肥技术采纳的效果更好；3)此外，生产性服务外包对经营规模较小的农户测土配方施肥技术采纳的带动效果更明显。因此，应当考虑发展各地生产性服务市场，并提升小农户对生产性服务外包的认识，促进中国农业生产减量施肥与可持续发展。

Abstract:

To analyze the impact of production service outsourcing by Chinese wheat growers on the adoption of testing soil for formulated fertilization technology of Chinese wheat growers, a micro data of 826 farmers in 7 main grain producing areas was used and the endogenous switching probit model(ESP)was adopted. The results show that 1)The outsourcing has a significant positive impact on the adoption of testing soil for formulated fertilization technology, and farmers who have the need to reduce fertilization are more inclined to outsource; 2)With the improvement of outsourcing, the effect of adopting testing soil for formulated fertilization technology is better; 3)In addition, outsourcing has a more obvious driving effect on the adoption of soil testing and formula fertilization technology for farmers with smaller scales. Therefore, it is necessary to consider the development of productive service markets in various regions, and enhance smallholder farmers' awareness of outsourcing, so as to promote the reduction of fertilization and sustainable development of agricultural production in China.
