我们回顾了信息和通信技术（ICT）的状况及其对发展中国家农业发展的影响，记录了过去十年发生的快速变化。尽管城乡之间的接入水平仍存在较大差距，但移动电话在农村地区的普及导致了农业领域的重要变化。我们发现，手机的普及总体上改善了宏观层面的农业市场表现；然而，微观层面的影响好坏参半。关于通过手机提供的市场信息系统 (MIS) 对农产品价格和收入的影响的证据有限，但证据表明存在强烈的异质影响。同样，通过信息通信技术推出的推广计划仍处于早期阶段，关于此类计划影响的研究很少。
We review the state of information and communication technologies (ICTs) and their impact on agricultural development in developing countries, documenting the rapid changes that have taken place over the past decade. Although there remains a wide gap in access between rural and urban areas, the spread of mobile phones in rural areas has led to important changes in the agricultural sector. We find that access to mobile phones has generally improved agricultural market performance at the macro level; however, impacts at the micro level are mixed. Evidence regarding the impact of market information systems (MIS) delivered through mobile phones on farm prices and income is limited, but the evidence points to strong, heterogeneous impacts. Similarly, the rollout of extension programs though ICTs is still in an early stage, and little research is available regarding such programs' impacts.
