In the post-epidemic era, in order to avoid market uncertainty, the choice of strategic alliance partners is particularly important. Taking the strategic dual orientation as the starting point, according to the theory of resource dependence, and taking the strategic alliance enterprises in the Yangtze River Delta region as the research sample, this paper constructs and verifies the theoretical framework of strategic alliance partner selection, alliance cultural capital, and alliance performance. The research results show that (1) strategic alliance partner selection (relationship orientation and market orientation) has a significant positive impact on alliance performance; and (2) alliance cultural capital (alliance leadership ability, trust mechanism, and alliance values) plays an important role in strategic alliance partner selection (relationship-oriented and market-oriented), and alliance performance play a partial mediating role.
