摘要

本研究旨在为持续采用可持续农业实践(SAPs)对农民技术效率和利润效率的影响提供实证证据。以前的研究仍然没有得出结论，是否采用SAPs对玉米农民的效率有任何影响。目前的研究引入了持续采用的概念，并比较了一次性SAP采用者和持续采用者之间的效率水平。本研究采用Cobb-Douglas随机前沿模型分析玉米农户的技术效率和利润效率，并采用两阶段tobit模型控制内生性。研究发现，一次性采用SAPs对玉米农户的技术效率没有影响，而持续采用SAPs可显著提高玉米农户的技术效率和利润效率。该研究建议转向促进可持续采用sap，为农民带来可持续利益。

Responding to inefficiencies on smallholder maize farms: Can sustained adoption of sustainable agricultural practices make a difference?

This study aimed to bring forth empirical evidence of the effect of the sustained adoption of sustainable agricultural practices (SAPs) on the technical and profit efficiency of farmers. Previous studies remain inconclusive about whether the adoption of SAPs has any bearing on the efficiency of maize farmers. The current study introduced the concept of sustained adoption and compared levels of efficiency between one-time SAP adopters and sustained adopters. Using a sample of 2 100 households, the study employed the Cobb-Douglas stochastic frontier model to analyse both the technical and profit efficiency of maize farmers, and a two-stage tobit model was used to control for endogeneity. The study found that the one-time adoption of SAPs has no effect on the technical efficiency of maize farmers, whilst sustained adoption significantly improves the technical and profit efficiency of maize farmers. The study recommends a shift towards promoting the sustained adoption of SAPs for sustainable benefits for 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.
