International Comparison of the Efficiency of Agricultural Science, Technology, and Innovation: A Case Study of G20 Countries

Xiangyu Guo, Canhui Deng, Dan Wang, Xu Du, Jiali Li, Bowen Wan · 2021 · Sustainability

Summary. This study measures agricultural science, technology, and innovation (ASTI) efficiency across G20 countries using data envelopment analysis. Developed G20 nations show declining efficiency trends but stronger innovation capacity, while developing G20 countries demonstrate rising efficiency but lower capacity. R&D spending redundancy and insufficient agricultural research output constrain efficiency gains. Technological change drives most productivity improvements across both groups.
