Abstract: This paper aims to explore how top management team (TMT) behavioral integration affects business model innovation through the mediating role of boundary-spanning search. Therefore, the hypotheses of the relationship among TMT behavioral integration, boundary-spanning search, and business model innovation are proposed, and these hypotheses are tested by using hierarchical regression analysis with data collected from 177 firms. The results show that TMT behavioral integration affects business model innovation positively; supply-side search, demand-side search, and spatial boundary-spanning search affects business model innovation positively. The results also show that TMT behavioral integration affect business model innovation through the mediating role of supply-side search, demand-side search, as well as spatial boundary-spanning search. This study contributes to developing the theory of the antecedents of business model innovation and expanding the theory of the relationship between TMT and business model innovation. This study has implications for TMT to advance business model innovation and enhance firm performance.

Key words: top management team behavioral integration, boundary-spanning search, business model innovation
