本文主要介绍了国外基于产业组织理论、行为金融理论、公司治理理论和资本结构理论融合发展的最新研究成果。从中不难发现,关于资本结构理论的研究正向着综合化和微观化的趋势发展。这对我国关于资本市场的一些政策的制定以及企业融资决策的实践具有重要启示意义。 This article mainly introduces the latest foreign research results based on the integration of industrial organization theory, behavioral finance theory, corporate governance theory and capital structure theory. It is not hard to find that the research on the theory of capital structure is moving toward the trend of integration and miniaturization. This is of great significance to our country’s formulation of some policies on the capital market and the practice of corporate financing decision-making.
