Abstract: Faced with the dilemma of resource constraint, it is very important for entrepreneurial firms to choose an appropriate market entry mode to explore new markets. Based on the theoretical perspective of bricolage, this paper takes four unicorns as the research objects and adopts the method of multi-case analysis to explore the market entry mode of entrepreneurial firms. The research found that: firstly, the higher the level of entrepreneurial enterprise resources, the more stable bricolage they adopt, the lower the operating risk they face, and the more inclined to choose the market entry mode with high degree of equity involvement; Secondly, as the growth of enterprises continues, entrepreneurial firms are faced with increasing operational risks and tend to choose the market entry mode with low degree of equity involvement. Thirdly, the higher the degree of materialization of the industry in which entrepreneurial firms are located, the more stable bricolage they adopt and the lower the operational risk they face. They are more inclined to choose the market entry mode with high degree of equity involvement.
