摘要

埃塞俄比亚是非洲牲畜数量最多的国家之一。2016-2017年,活体动物、皮革和肉类在该国出口总额中的份额达到9.6%。本文旨在通过向量自回归和向量纠错模型来确定埃塞俄比亚畜产品出口的决定因素。多元时间序列用于建模研究中埃塞俄比亚牲畜出口产品之间的关联。向量自回归和向量误差校正模型用于建模和推理。结果表明,活体动物、肉类和皮革出口量之间存在长期相关性。肉类出口量在短期内受到活动物出口滞后的严重影响。因此,每个季度调整3.7%的皮革出口量短期失衡。建议畜产品出口商适当利用埃塞俄比亚的牲畜资源。另一方面,政府应向出口商提供不同形式的支持,尤其是那些专注于出口增值产品的出口商。

Determinants of livestock products export in Ethiopia
Ethiopia has one of the largest livestock populations in Africa. In 2016–2017, the share of live animals, leather, and meat in the total export of the country reached 9.6%. This paper aims to identify the determinants of the export of Ethiopian livestock products by means of vector autoregressive and vector error correction models. Multivariate time series is used to model the association between the products of the Ethiopian livestock export included in the study. Vector autoregressive and vector error correction models are used for modelling and inference. The results indicated the existence of a long term correlation between the volume of live animals, meat and leather exports. The volume of meat export is significantly affected by a lag occurring in the export of live animals in the short-run. Therefore, 3.7% of the shortrun imbalance in the volume of leather export is adjusted each quarter. It is suggested that the exporters of livestock products should properly utilise the Ethiopian livestock resources. On the other hand, the government should offer different forms of support to exporters, especially those focusing on exporting value-added products.

期刊介绍: Statistics in Transition (SiT) is an international journal published jointly by the Polish Statistical Association (PTS) and the Central Statistical Office of Poland (CSO/GUS), which sponsors this publication. Launched in 1993, it was issued twice a year until 2006; since then it appears - under a slightly changed title, Statistics in Transition new series - three times a year; and after 2013 as a regular quarterly journal." The journal provides a forum for exchange of ideas and experience amongst members of international community of statisticians, data producers and users, including researchers, teachers, policy makers and the general public. Its initially dominating focus on statistical issues pertinent to transition from centrally planned to a market-oriented economy has gradually been extended to embracing statistical problems related to development and modernization of the system of public (official) statistics, in general.
