Coordination of economy, environment and social performance is a key component of energy companies. This paper uses coupling theory to establish a coupling coordinated development system of economy-environment-social(EES) performance of energy companies, and their evaluation index system and comprehensive evaluation methods for the three factors respectively. Coupling model and coupling coordination model are built in terms of coordination of economy, environment and social performance of petroleum companies as a basis to weigh their coordination. In terms of the ChinaPetro's panel data from 2007 to 2018, this paper discusses its coordination as to verify the feasibility of coupling theory on the triple performance evaluation. ChinaPetros coupling coordination lies between 0.6 to 0.8, at a medium level. Its coordination development has been promising but descending recently. Its triple performances suppress each other. Improvement of environmental and social performance can boost its economic performance, which, if unstable, also can impact companies' comprehensive performances. Economic performance is the basic precondition of coordinated development of companies triple performance.
