公共部门是农业研究的重要来源，因为许多生产者是无法承担研究和开发费用的个体农民。被称为Kohsetsushi的公共实验、研究和推广机构通过各种技术转移渠道帮助当地农业和制造业生产者提高生产率。基于农业创新系统的概念，本研究考察了一个地区的农业寿司的研究努力是否顺畅地响应了该地区专业化的变化，他们的研究努力是否有利于创新，他们的研究活动的决定因素和影响是否在不同的产品上有所不同。面板估计的结果表明，研究努力的分配对地区专业化的变化做出了反应，这表明该地区的推广人员参与了反馈机制。农业寿司是农产品创新的重要来源，不同领域的研究人员在不同产品上表现出不同程度的弹性。
The public sector is an important source of agricultural research as many of the producers are individual farmers who cannot bear the cost of research and development. Public institutes for experimentation, research, and extension called Kohsetsushi help local producers in agriculture and manufacturing improve productivity through various technology transfer channels. Based on the concept of the agricultural innovation system, this study examines whether research effort allocation of agricultural Kohsetsushi in a region smoothly responses to changes in specialization of the region, whether their research efforts are conducive to innovation, and whether determinants and impacts of their research activities vary across products. The results of panel estimation reveal that research effort allocation is responsive to changes in specialization of a region, which suggests the feedback mechanism mediated by extension staff in the region. Agricultural Kohsetsushi act as a significant source of agricultural product innovations, with researchers allocated in different fields exhibiting different levels of elasticity across products.
