【报告内容简介】
To address the global challenge of small business finance, China has launched a fintech program that offers unsecured loans to small firms, using tax credit and tax payment information from the tax bureau and digitalization technology. We find that this program effectively improves small firms' access to loans, increasing both the probability of obtaining a loan and the loan amount. It also leads to better firm performance, including higher revenue, return on assets, and survival rate. The success of the program depends on its general inclusiveness among creditworthy taxpayers, which allocates loans based on tax information, prioritizes new borrowers, and reduces the impact of traditional financial metrics and geographic distance from banks. The positive loan effects on firm performance increase with tax credit and payment and are often stronger among the new borrowers. Therefore, it may be social optimal to spare credit rationing on expensive private information for small firms.
