Can Africa grow its manufacturing sector & create jobs?

Over at the World Bank Francois Steenkamp and Christopher Rooney write:
Over the past decade and a half, Sub-Saharan Africa has experienced rapid economic growth at an average annual rate of 5.5%. But since 2008, the share of manufacturing in GDP across the continent has stagnated at around 10%. This calls into question as to whether African economies have undergone structural transformation – the reallocation of economic activity across broad sectors -- which is considered vital for sustained economic growth in the long-run.

It is often argued that the process of manufacturing-led structural transformation results in employment growth characterized by the creation of good, high-productivity, good-paying jobs. The kind of jobs that can break the cycle of poverty and address inequality.

So if most African countries haven’t experienced manufacturing-led structural transformation, what is it that has constrained the manufacturing sector over this relatively robust period of economic growth?
