Studies on violence and anti-Chinese had been done by some experts in these was; Jamie Mackie (1976), W. F. Wertheim (1964), The Lars Giap (1966), Mary player Somers Heidhues (1965) and Takashi Shiraishi (1997), Charles Coppel (2002), and of course was also Jumma Purdey (2006).
The experts used the theory of economic competition and political manipulation to understand the incidence of anti-Chinese violence (Purdey, 2013: 34). Coppel argued that economic competition theory into the causes of the emergence of anti-Chinese in Indonesia. Coppel said,
“One can accept the importance competition economy as one of the factors of anti-Chinese sentiment in Indonesia, without the need to ignore other things as 'rationalisation" (Coppel, 1983:28; in Purdey, 2013:33).”
The Siauw Giap also used the theory of economic competition, which according to The economic competition and Giap Siauw especially the role of intermediary traders played by ethnic Chinese constitute factors caused the only occurrence of violent anti-Chinese in Indonesia (She, 2013:34).
Wertheim also used economic competition theory to explain the emergence of anti-Chinese in Indonesia. Werthein stated that economic factors dominated the relations between ethnic Chinese and the majority population that then explained why the most violent anti-Chinese occurred in a period of transition or economic crisis (Purdey, 2013:34).
