Taking proactive improvement into the relationship of interaction orientation and service innovation performance, an empirical research is implemented with structural equation model analysis to explore the new way of improving service innovation performance under the new times background based on interaction orientation. The results show that Interaction orientation has both direct and indirect positive effect on service innovation process performance. Interaction orientation only has indirect positive effect on service innovation result performance. Interaction orientation has direct positive effect on proactive improvement. Proactive improvement has direct positive effect on service innovation process performance and has a mediating effect between interaction orientation and service innovation process performance. Proactive improvement has direct positive effect on service innovation result performance and has partial mediating effect between interaction orientation and service innovation result performance.
