Abstract: We study the relationship between technology spillovers from trade, domestic research and development (R&D) spending, and the growth in green total factor productivity within the agricultural sector. An empirical illustration is provided using a sample of 48 countries involved in China’s Belt and Road Initiative from 2000 to 2019. Our findings highlight the important role of agricultural imports as a positive driving force behind green productivity growth, while the impact of domestic R&D expenditures on agricultural productivity lacks statistical significance in our sample. Furthermore, we find that trade-related technological spillovers drive environmentally sustainable agricultural growth in economically developed nations, but this effect is weaker in developing countries. Conversely, greater domestic investment in agricultural research and development programs helps promote green productivity growth in relatively rich countries, but its influence diminishes in middle-income and developing countries. Lastly, a positive impact of importing vegetable and edible oil products on productivity is observed.
