摘要

摘要本研究利用埃塞俄比亚的地块级数据,旨在检验替代聚四氟乙烯生产技术对小农户聚四氟乙烯生产商生产力和盈利能力的决定因素和影响。该研究采用了多项内生切换回归(MESR)模型,该模型解释了可观察和不可观察因素造成的选择偏差。作者的研究结果表明,技术采用与教育、农场规模、扩展访问、社区会议和资产所有权呈正相关。相反,与投入和产出市场的距离对采用替代聚四氟乙烯生产技术产生了负面和显著的影响。MESR模型的结果表明,虽然全面采用技术是最具生产力和利润的选择,但采用任何替代技术也大大提高了小农户聚四氟乙烯生产商的生产力和利润。研究结果还表明,只有在采用改良种子技术的情况下,行种植技术才能对小农户聚四氟乙烯生产商的生产力和盈利能力产生积极影响。

Adoption and ex-post impact of alternative teff production technologies: micro-level evidence from Ethiopia
ABSTRACT Using plot-level data from Ethiopia, this study aims to examine the determinants and impact of alternative teff production technologies on the productivity and profitability of smallholder teff producers. The study employed a multinomial endogenous switching regression (MESR) model that accounts for selection bias due to observable and unobservable factors. The authors’ results show that technology adoption has a positive association with education, farm size, extension visits, community meetings and asset ownership. On the contrary, distance to input and output markets have a negative and significant effect on the adoption of alternative teff production technologies. The MESR model results reveal that, while full technology adoption is the most productive and profitable option, adopting any of the alternative technologies also substantially improves the productivity and profitability of smallholder teff producers. The results also suggest that row-planting technology has a positive impact on the productivity and profitability of smallholder teff producers only when it is adopted with improved seed technology.

期刊介绍: Agrekon publishes scholarly articles that contribute to the existing literature in the domain of Food, Agricultural and Resource Economics as it applies to Southern Africa. The editors of Agrekon therefore invite contributions in this context that provide new insights, either through the problems they address, the methods they employ or the theoretical and practical insights gained from the results. The quarterly journal serves as the official publication of the Agricultural Economics Association of South Africa (AEASA) and is published by Taylor & Francis.
