Especially, organizational routines have the influences on the two factors of building up dynamic competitive advantages-strategic change and strategic flexibility and further influence the establishment of dynamic competitive advantages. This paper involves detailed analysis on the influences of organizational routines and on the approaches of establishing dynamic competitive advantages and puts forward the relevant countermeasures.展开更多
