Abstract

This study assesses the extent of structural transformation within the manufacturing sector by discomposing the source of labour productivity and TFP growth, shares of capital, and employment among other indicators. For the sake of the analysis, the manufacturing sector is classified into three categories: resource-based, low technology, medium and high technology. Labour productivity and TFP growth were estimated using data between 1982/83–2017/18 to assess the reallocation of resources among industrial groups. The findings show that resource-based industries still hold the largest share of output and capital in the manufacturing sector, and remains to be the most productive group. Low technology industries continue to maintain the largest percentage of workers although there has been high rate of growth of workers in medium and high technology industries in recent years. Albeit the prevalence of a slight movement of workers from lower productive to higher productive industrial groups with a given productivity level, there is no evidence of dynamic reallocation or a movement of labour driven by productivity changes across industries. Static comparative advantages or natural resource endowments seem to induce the establishment of most industries in Ethiopia, although these same industries heavily rely on imported inputs. In addition, government policies tend to favour resource-based and low technology industries in the form of, for instance, the provision of working premises and infrastructural facilities such as power through the establishment of industrial parks. Thus, there is a need to improve institutional and policy enablers to address existing binding constraints and strengthen inter-sectoral linkages not only to efficiently tap the available domestic resources, but also pave the way for the growth of medium and high technology industries as a pathway for faster pace of industrialization and economic development.

埃塞俄比亚制造业的结构转型
本研究通过对劳动生产率和全要素生产率增长的来源、资本份额和就业等指标进行分解,评估制造业的结构转型程度。为便于分析,将制造业分为三类:资源型、低技术型、中技术型和高技术型。利用1982/83-2017/18年间的数据对劳动生产率和全要素生产率的增长进行了估算,以评估各产业群体之间的资源重新分配情况。研究结果表明,资源型产业仍占据制造业产出和资本的最大份额,并且仍是生产率最高的群体。虽然近年来中、高技术产业工人的增长率较高,但低技术产业仍然保持着最大的工人比例。尽管在给定的生产率水平下,工人从生产率较低的行业组别向生产率较高的行业组别略有流动,但没有证据表明存在动态的重新配置或由生产率变化驱动的劳动力跨行业流动。静态比较优势或自然资源禀赋似乎促成了埃塞俄比亚大多数产业的建立,尽管这些产业严重依赖进口投入。此外,政府政策往往倾向于资源型和低技术型产业,例如通过建立工业园区提供工作场所和电力等基础设施。因此,有必要改进体制和政策促进因素,以解决现有的约束性限制,并加强部门间联系,这不仅是为了有效利用现有的国内资源,也是为中高技术产业的增长铺平道路,以此作为加快工业化和经济发展步伐的途径:D24 J63 L63 O490
