摘要

认识到由于数据的非随机性造成的潜在选择偏差，本研究对具有全国代表性的第五次综合家庭调查(IHS5)的数据使用倾向得分匹配，以调查农业推广服务对马拉维玉米农民技术效率的影响。采用随机前沿模型估计技术效率水平。结果表明，大部分农户技术效率较高，平均技术效率为63%。这表明，在相同投入水平下，玉米产量仍有可能提高37%。倾向得分匹配结果显示，获得农业推广服务可显著提高玉米农民的技术效率，约提高4%。这一证据不仅为农民提供了机会，也为相关政策制定者提供了机会，让他们认识到利用农业推广服务提高种植玉米农民生产能力的潜力。

Influence of agricultural extension services on technical efficiency of maize farmers in Malawi

Recognising potential selection bias due to non-randomness of the data, this study used propensity score matching on data from a nationally representative fifth Integrated Household Survey (IHS5) to investigate the effect of agriculture extension services on the technical efficiency of maize farmers in Malawi. Technical efficiency levels were estimated using the stochastic frontier model. The results show that most farmers are technically efficient, with an average technical efficiency of 63%. This indicates that there is still a possibility to increase maize output by 37% using the same level of inputs. The results of the propensity score matching reveal that having access to agricultural extension services significantly increases maize farmers’ technical efficiency, by about 4%. This evidence presents an opportunity not only for farmers, but also for the relevant policymakers, to realise the potential of using agricultural extension services to enhance the production capacity of maize farmers.

期刊介绍： The African Journal of Agricultural and Resource Economics (AfJARE)/Journal Africain d’Economie Agricole et des Ressources (JAEAR) is a publication of the African Association of Agricultural Economists (AAAE). The journal publishes original research about how African agriculture interacts with local and global economic systems and policy regimes in its impacts upon people. The scope of the journal covers the roles of markets, technology, policy, institutions and the natural environment in shaping the lives of well being of Africans engaged in agricultural activities. The journal strives to nurture and enhance the capacity of African professionals to conduct and publish scientific research and provides a venue for communicating and disseminating their findings. Multi-disciplinary, problem-oriented articles are encouraged. Submissions may deal with teaching, research extension, consulting, advising, entrepreneurship and administration. The Chief Editors and Editorial Board, under the general direction of the AAAE President, Executive Committee and Council are charged with implementing Journal policy to serve members of AAAE. The main section of the journal publishes technical research articles while a small section is devoted to publishing brief notes with important policy content and book reviews. The journal is a quarterly publication.
