公司对外担保属公司商行为,需遵循相应的决定程序。但对外担保的有效性未明确,有关担保法条过于简洁致使规则的不确定性,而相关工商登记监管制度未紧密配套,使得公司法的对外担保制度难如立法所愿。 Company external security is a company business, to follow the appropriate decision-making process. However, the validity of external guarantee is not clear. The relevant provisions of the guarantee law are too concise, which leads to the uncertainty of the rules. However, the relevant regulatory system for business registration is not closely matched, making it difficult for the external guarantee system of the Company Law to be as legislated.
