关于资本结构影响因素的理论和实证研究存在很多相互矛盾的结论,人们通常把这个问题归咎于外部因素的影响,而没有怀疑责本结构理论自身的稳健性;本研究发现相互矛盾的研究结果并非由外部因素引起,而是由于资本结构理论本身缺乏较强的稳健性。因此,侍统的资本结构理论并不适用于指导我国企业的融资实践,应该从企业外部,而不是过去理论强调的“从企业内部”去寻找影响资本结构的因素。
There are many contradictory arguments in the theoretical and empirical studies on the factors affecting firm's capital structure. And it is often attributed to the influence of outer factors, instead of the robustness of capital structure theory itself. This paper finds out that such contradictory arguments are not caused by outer factors, but by the lack of robustness in capital structure theory. Therefore, traditional capital structure theory does not apply to the financing practice of Chinese firms; factors responsible for capital structure should be identified from the outside of firms, instead of from inside, as emphasized by the traditional theory.
