DescriptionIn this dissertation, I begin with three goals. First, I seek to extend the bricolage-innovation relationship by considering the role of resource constraints. Second, I aim to explore the influence of bricolage on entrepreneurial orientation (EO). Third, I seek to assess how individual-level factors affect bricolage in the resource-constrained environment. To realize these goals, I conducted three studies that led to three essays. The first essay’s purpose is to extend the relationship between bricolage and innovation. Based on the literature that connects resource constraints and innovation as well as the literature that links bricolage and innovation, I added resource constraints as the antecedent of bricolage-innovation link. Different from prior studies that treat resource constraints as a one-dimensional variable, I operationalized it from two dimensions, namely knowledge constraints and financial constraints. I argued that knowledge constraints and financial constraints are triggers of innovation of new firms and that bricolage plays a full mediating role in these relationships. In addition, I also proposed different effects of parallel bricolage and selective bricolage on innovation. The survey data from 183 entrepreneurs showed that bricolage fully mediates the relationship between knowledge constraints and innovation and partially mediates the relationship between financial constraints and innovation. The purpose of the second essay is to examine the influence of bricolage on EO. The literature of EO and bricolage suggests that bricolage might be related with EO. In particular, I investigated the influence of bricolage on the three components of EO, namely innovativeness, proactiveness, and risk-taking. The results suggested that bricolage is positively related to innovativeness, whereas bricolage is negatively related to risk-taking. However, bricolage was found no impact on proactiveness. The third essay’s purpose is to examine the moderating effects of creativity cognitive style in the relationship between resource constraints and bricolage. Drawing on cognitive psychology research, I posited that entrepreneurs’ divergent thinking positively moderates the relationship between resource constraints and bricolage, whereas entrepreneurs’ convergent thinking negatively moderates this relationship. The results supported both hypotheses. The practical implications and future research directions are discussed.
