The present investigation analyzes how the dynamism of the environment affect the relationship be-tween the capacity of adaptation and the pioneering behavior in the companies of the tourism sector in Peru. The empirical study was carried out in 238 tourist companies located in the cities of Lima, Arequipa and Cuzco considered as a cultural heritage of Perú. Regarding to the results achieved in the study, the proposed model allows detecting a direct, significant effect between the ability to adapt and pioneering behavior, whose relationship is accentuated through market dynamism and technological dynamism, and is weakened by competitive intensity. This work contributes to the ex-isting theory and demonstrates through practical application the linkage of the dimensions of the dy-namism of the environment as drivers of adaptive capacity in companies in the cultural tourism sec-tor that are necessary to obtain advantages for a behavior Pioneer in an existing competitive market.
