I am trying to get an updated (ideally 2016, but at least 201x) picture of the proportion of GDP accounted for by the Regional Ethnic Chinese in Southeast Asian economies. The last estimates of their contributions to GDP I have seen are from the early 2000s. I have done an extensive web search.
Would anyone know of newer data for the region? This could be proportion of GDP accounted for, but also alternative measures such as ownership of businesses or proportion of total accumulated wealth in society.
All the best,
Michael
