Modelo de avaliação da influência dos fatores contextuais e da confiança na governança da cadeia de suprimentos e no seu desempenho

Abstract

The decision about when to employ contractual and/or relational mechanisms to govern supply chain relationships is likely driven by the key characteristics of the relationship, as well as the context in which they are needed, which makes the area of supply chain governance fertile. for research, enabling the exploration, combination, and integration of various factors, mechanisms, and expected results in interorganizational relationships. Thus, the objective of this thesis was to develop a model to analyze the influence of contextual factors and confidence in GCS and its effect on supply chain performance. To achieve this objective, research was carried out with a qualitative and a quantitative stage. In the qualitative stage, a systematic literature review was first carried out, using 4 combinations of keywords in 11 databases and without time restriction until August / 2018, resulting in 126 selected final articles. From a thematic analysis of the articles, it was identified and explored which are the main elements related to each of the proposed constructs (contextual factors, trust, supply chain governance, and supply chain performance), making possible the development of a conceptual model and an initial research instrument. Subsequently, two case studies were carried out in Brazilian multinational companies to validate and refine the constructs of the conceptual model and research instrument through a thematic analysis. In the quantitative stage, a survey was carried out with 264 participating Brazilian companies and from the application of structural equations modeling by partial least squares, it was possible to validate the conceptual model and analyze the research hypotheses. As a result, a direct and positive influence was identified between power asymmetry and contractual and relational governance. In addition, it became evident that the relationship history and interdependence have a direct negative effect on contractual governance and the perceived risk has a direct negative effect on relational governance. These results indicate that the use of mechanisms to govern relationships in the supply chain is influenced by the context in which they occur. In addition, interorganizational trust had a mediating effect between some contextual factors (perceived risk and power asymmetry) and contractual and relational governance. And finally, both contractual governance and trust have a direct and positive influence on supply chain performance. Therefore, it is suggested that supply chain managers should develop confidence in both the affective and competence-based approach to promote the use of governance mechanisms and improve the financial, operational, and market performance of the supply chain.
