摘要

提高中低收入国家(LMICs)的农业生产力是减少贫困和粮食不安全的重要渠道。信息和通信技术(ICT)通过降低交易成本和增加获取信息的机会,具有提高农业生产力的潜力。尽管有一些微观层面的研究分析了信息和通信技术对农业生产率的影响,但在全球和地区层面探讨信息和通信技术对农业生产率的作用的研究却很少。利用来自 86 个国家 2000 年至 2019 年的数据,并采用可行的广义最小二乘法进行固定效应面板回归,我们发现,在全球范围内,信息和通信技术的采用与农业的土地和劳动生产率之间存在显著的正相关关系。然而,在每种情况下,其影响程度都远远小于其他重要的决定因素,如人力资本、获得投入或环境因素。在地区层面上,非洲和亚洲的信息与通信技术应用与土地生产率之间的关系并不显著,而我们发现其对劳动生产率有显著影响。这一结果表明,虽然信息和通信技术可以为土地管理提供有价值的信息和工具,但在这些地区对土地生产率的影响可能不那么直接。最后,我们再次探讨了信息和通信技术的发展是否会加大高收入国家与低收入和中等收入国家之间的农业生产率差距这一问题。与以往的研究不同,本研究没有发现信息和通信技术对高收入国家和低收入国家的土地和劳动生产率的影响存在显著差异。

Assessing the potential of ICT to increase land and labour productivity in agriculture: Global and regional perspectives

Assessing the potential of ICT to increase land and labour productivity in agriculture: Global and regional perspectives

Increasing agricultural productivity in low- and middle-income countries (LMICs) is an important channel for reducing poverty and food insecurity. Information and communication technologies (ICT) have the potential to boost agricultural productivity by lowering transaction costs and enhancing access to information. Even though there are several micro-level studies analysing the effects of ICT on agricultural productivity, there is scant research addressing the role of ICT in agricultural productivity at the global and regional levels. Using data from 86 countries for the period 2000 to 2019 and utilising a fixed effect panel regression with a feasible generalised least square approach, we find that globally there is a positive and significant association between ICT uptake and both land and labour productivity in agriculture. In each case, however, the magnitude of the effect is much smaller than other important determinants, such as human capital, access to inputs or environmental factors. At the regional level, the relationship between ICT uptake and land productivity is not significant in Africa and Asia, while we find a significant effect on labour productivity. This finding indicates that while ICT can provide valuable information and tools for land management, the effect on land productivity might be less immediate in these regions. Finally, we revisit the question of whether ICT expansion increases agricultural productivity gaps between high-income nations and LMICs. In contrast to previous research, this study does not find significant differences in the effects of ICT on land and labour productivity between higher-income and lower-income countries.

期刊介绍: Published on behalf of the Agricultural Economics Society, the Journal of Agricultural Economics is a leading international professional journal, providing a forum for research into agricultural economics and related disciplines such as statistics, marketing, business management, politics, history and sociology, and their application to issues in the agricultural, food, and related industries; rural communities, and the environment. Each issue of the JAE contains articles, notes and book reviews as well as information relating to the Agricultural Economics Society. Published 3 times a year, it is received by members and institutional subscribers in 69 countries. With contributions from leading international scholars, the JAE is a leading citation for agricultural economics and policy. Published articles either deal with new developments in research and methods of analysis, or apply existing methods and techniques to new problems and situations which are of general interest to the Journal’s international readership.
