Extension services and the technical efficiency of crop-specific farms in China

Liu, Qian; Jiang, Yongmu; Lagerkvist, Carl-Johan; Huang, Wei

Sammanfattning

China operates the world's largest system of extension services, but knowledge about its effectiveness is limited. Using farm survey data and a stochastic meta-frontier production function, this study investigates the impact of extension services on the technical efficiency of crop-specific farms in China. Results reveal that extension services have a statistically significant and strongly correlated relationship with farm technical efficiency and that different sources of extension have an inconsistent impact on it. Crop-specific farms require distinct extension provision whose content is designed to match farmers' needs, and hence a pluralistic and well-functioning system of extension provision should be developed.

    • Globala målen

      SDG1 Fattigdom omfattar fler dimensioner än den ekonomiska. Fattigdom innebär bl.a. även brist på frihet, makt, inflytande, hälsa, utbildning och fysisk säkerhet.
      SDG4 Säkerställa en inkluderande och likvärdig utbildning av god kvalitet och främja livslångt lärande för alla
