摘要

Geographic dispersion of depositors, borrowers, and banks may prevent funding from flowing to high loan demand areas, limiting credit access. Using bank-county-year level data, we provide evidence of geographic imbalance of deposits and loans and develop a methodology for investigating the contribution to this imbalance of branch networks, market power, and scope economies. Results are based on a novel measure of imbalance and estimation of a structural model of bank competition that admits interconnections across locations and between deposit and loan markets. Counterfactual experiments show branch networks, scope economies, and local competition affect credit flow to disadvantaged markets.

存款人、借款人和银行在地理分布上的分散性可能会阻碍资金流向贷款需求旺盛的地区，从而限制了信贷的可获得性。本文利用银行-县域-年份层面的数据，证明了存款和贷款在地理分布上存在不均衡的现象，并开发出一种方法，用以研究分行网络、市场力量和范围经济对这种不均衡状况的影响。研究结果基于一种全新的衡量不均衡的方法，以及对银行竞争结构模型的估计，该模型考虑到了不同地区之间以及存贷市场之间的相互关联。反事实实验表明，分行网络、范围经济以及地方竞争会对资金流向处于不利地位的市场的信贷流动产生影响。
