采用的概念是衡量非洲农业技术变化的核心，在评估农业研究和技术开发投资回报方面发挥着重要作用。然而，采用的概念，因为它是在文献和发展研究实践中常用的，是严重缺陷，并导致不准确和误导性的结论。作者概述了替代概念的设计规范，这将为农业技术开发和推广投资的经济，社会和环境影响的可靠实证研究提供更好的基础。他们提出，这一新概念有助于更好和更细致地了解技术开发干预措施的影响。
The notion of adoption is central to efforts to measure technological change in African agriculture, and plays an important role in the evaluation of return on investment in agricultural research and technology development. However, the adoption concept, as it is commonly used in both the literature and development research practice, is seriously flawed and leads to inaccurate and misleading conclusions. The authors outline a design specification for a replacement concept that would provide a better basis for robust empirical research on the economic, social and environmental impacts of investment in agricultural technology development and promotion. They propose that this new concept can contribute to a better and more nuanced understanding of the impacts of technology development interventions.
