Bank Competition and Access to Finance: International Evidence
基于74个国家不同规模企业的数据，研究发现银行集中度会加大企业融资障碍，但仅在经济和制度发展水平低的国家；外资银行占比高和高效的信用登记机构能缓解这一影响，而政府干预和国有银行占比高则会加剧。
Using a unique database for 74 countries and for firms of small, medium, and large size we assess the effect of banking market structure on the access of firms to bank finance. We find that bank concentration increases obstacles to obtaining finance, but only in countries with low levels of economic and institutional development. Alarger share of foreign-owned banks and an efficient credit registry dampen the effect of concentration on financing obstacles, while the effect is exacerbated by more restrictions on banks' activities, more government interference in the banking sector, and a larger share of government-owned banks.
