Dynamic capabilities are regarded as a strategic premise to creating, maintaining and upgrading sustainable competitiveness. Considering organizational leing as a mediator variable, this study tests the relationship between entrepreneurial orientation and dynamic capabilities, and identifies paths to develop dynamic capabilities and the components of these capabilities. More specifically, the factor analysis method was employed to verify that dynamic capabilities are comprised of four dimensions, i.e. environmental sensing capabilities, change and renewal capabilities, technological and organizational flexibility capabilities. It was found that dimensions of entrepreneurial orientation have a significantly positive effect on dynamic capabilities to different extents, while organizational leing, which has significantly positive effect on dynamic capabilities, plays a partial mediating role between the two. These findings indicate that companies can build dynamic capabilities through different levels of organizational leing in the context of innovative and proactive atmosphere.
