摘　　要：区域创新效率是区域高质量发展的重要支撑,也是实现产业优化升级的必要保障。现代市场经济是信用经济,信用活动在经济发展中发挥着愈加重要的作用。为衡量各类信用主体的信用规模对区域创新效率影响的内在机理,选取2008—2022年中国283个城市作为研究样本,从理论和实证角度分析信用总规模及其子成分对区域创新效率的影响机制。研究结果表明:第一,信用规模扩张可以显著促进区域创新效率提升,且这一结果在利用工具变量的内生性检验及更换被解释变量和计量模型后的稳健性检验中依旧显著。第二,政府部门、金融机构、企业、个人等信用主体的信用规模扩张对区域创新效率的影响均表现出显著的正向空间溢出效应,其中政府部门的影响作用占主导地位。第三,信用规模扩张对区域创新效率的影响存在非线性过程,在城市创新效率不同的情况下,信用规模扩张的作用有所不同。Regional innovation efficiency is an important support for regional high-quality development and a necessary guarantee for industrial optimization and upgrading.The modern market economy is credit economy and credit activities are playing an increasingly important role in economic development.In order to measure the intrinsic mechanism of how the credit scale by various credit entities affects the regional innovation efficiency,283 Chinese cities from 2008 to 2022 were selected as research samples to analyze the influence mechanism of total credit scale and its sub-components on regional innovation efficiency from both theoretical and empirical perspectives.The research results show that:First,credit scale expansion can significantly promote the improvement of regional innovation efficiency,and this result is still significant in the endogeneity test of instrumental variables and the robustness test after replacing the explained variables and the econometric model.Second,the credit scale expansion of government departments,financial institutions,enterprises and individuals all exhibit significant positive spatial spillover effects on regional innovation efficiency,with the impact of government departments playing a dominant role.Third,the influence of credit scale expansion on regional innovation efficiency is a non-linear process,and the roles of credit scale expansion are different in the case of different urban innovation efficiency.
