This paper analyses the economic impact of agricultural research on productivity in France over the period 1959-2012. Adopting a dynamic time series model, we provide evidence that the impact of French agri- cultural research is in the range of values estimated for other countries, with the estimated long-run elasticity being 0.16, which corresponds to an internal rate of return of 22%. The estimated elasticity decreases at the beginning of the 1970s. Complementary analyses are developed to take into account the evolution of the priorities of public agricultural research (reorientation towards more fundamental objectives and focus on broader objective than productivity enhancement).

评估农业研究对生产力的长期影响：来自法国的证据

本文分析了 1959-2012 年间农业研究对法国生产力的经济影响。采用动态时间序列模型，我们提供证据表明法国农业研究的影响在其他国家的估计值范围内，估计的长期弹性为 0.16，对应于 22 的内部收益率%。估计的弹性在 1970 年代初下降。开发补充分析以考虑公共农业研究优先事项的演变（重新定位到更基本的目标并专注于比提高生产力更广泛的目标）。
