On the basis of structural characteristics and general tendency analysis on energy consumption and carbon emission about Chinese service industry during 1991—2011，the methods of OECD and Tapio decoupling indicator were applied，the interactive relations and associated effects were described among GDP，energy consumption and carbon emission in service industry. Results indicates as follows：as a whole，GDP，energy consumption and carbon emission were yearly growth of potential; The change of energy intensity and carbon intensity about service industry had strong consistency and synchronization，and they were declined of potential；The consumption proportion of coal was roughly decreasing of potential，but the consumption proportion and total amount of natural gas，thermal and power were yearly growth trend；traditional high carbon energy proportions, such as coal and oil were accounted for 80% above；OECD decoupling factor were rendering out absolute decoupling state，and performed for fluctuations type rose of potential every year; Tapio decoupling elasticity indicators showed volatility on the overall rising trend. Based on the above conclusions，some policy recommendations of energy saving and carbon reduction about service industry were put forward.
