“…A dependence power advantage is one of the most cited antecedents of opportunism in the inter-firm relationship literature (Grandinetti, 2017 ; Hawkins et al, 2008 ; Tangpong et al, 2015 ; Wang & Yang, 2013 ). Previous studies had shown that opportunism’s association with other variables could be curvilinear, for example, opportunism and performance (Lado et al, 2008 ), opportunism and goal exceedance (El Meladi et al, 2018 ), opportunism and punishment severity (Xiao et al, 2019 ), and opportunism and guanxi (Shen et al, 2019 ). Drawing on the long-term perspective of Dabholkar et al ( 1994 ) and the relationship development cycle (Dwyer et al, 1987 ), opportunism is expected to be low at the relationship initiation stage but, as the relationship develops and power relations become obvious, the partner or its agent with the higher power could easily use the power advantage to exploit the weaker partner.…”
