This paper analyses the data on Chinese A-share listed companies from 1996 to 2019, using fixed-effect regression and the double-difference method to systematically examine the impact of commercial credit on enterprise technological innovation. The study found that the acquisition and provision of commercial credit has promoted the number of enterprise technological innovations and significantly improved their quality. In particular, the innovation of highly constrained companies is promoted by financing. Our findings help to solve the obstacles enterprises face in breaking through financing constraints and improving the efficiency and quality of their innovative efforts. The financing system has a significant influence on promoting the sustainable development of innovative enterprises.

The study estimates the impact of cluster commercial credit on manufacturing total factor productivity from the perspective of county-level clusters. The data were collected from 1998 to 2015 from the Chinese Industrial Enterprise Database. Various econometrics methods were used to approach the study objectives. The study found that cluster commercial credit can significantly increase the total factor productivity of manufacturing. Through the analysis of the theoretical mechanism, it was found that improving the level of innovation and improving the efficiency of the capital allocation are important ways for cluster commercial credit to positively promote the total factor productivity of the manufacturing sector. The analysis of heterogeneity found that cluster commercial credit promoted the total factor productivity of state-owned enterprises, large-scale enterprises, capital-intensive industries, high-tech industries, and enterprises in coastal areas to a great extent. By constructing a quasi-natural experiment, using the method of multi-period double difference and PSM-DID to solve the problem of cluster commercial credit endogeneity, it passed the parallel trend, placebo, and other tests. Finally, this article further describes the relationship between corporate commercial credit and corporate total factor productivity from the enterprise-to-enterprise level and found that the use of commercial credit by enterprises has a significant and positive role in promoting corporate total factor productivity. The research results of this paper provide a reference for promoting the high-quality development of the country’s economy from the perspective of informal finance.
