The influence of the guidance on building a green financial system on environmentally friendly firms' total factor productivity in China.

With China's proposed green development strategy, environmental protection investment needs are growing exponentially, and government funding alone is inadequate to meet the massive demand. To encourage social investment in green industries and achieve green development goals, the authorities implemented the major green finance policy entitled the Guidance on Building a Green Financial System (GBGFS) in late 2016. Whether this policy effectively promotes the development of environmentally friendly (EF) firms is an essential under investigated question. This study employs a difference-in-differences approach to explore whether and how the GBGFS affects EF firms' total factor productivity (TFP) with a sample from 2012 to 2021. Our benchmark regression and robustness tests demonstrate that the GBGFS effectively promotes EF firms' TFP. We also obtain three notable research findings with a number of additional analyses. (a) Although there is a certain lag, the policy effect was obviously enhanced with the passage of time. (b) Our threshold effect analyses reveal that the enhancing effect of the GBGFS on EF firms' TFP only becomes significant when research and development (R&D) investment, profitability (ROA), and government subsidies (GSF) exceed certain values. Further analysis demonstrates that firms with higher ROA and more GSF can effectively increase R&D. (c) Finally, GBGFS implementation has a greater impact on firm TFP in China's more developed region than its less developed regions. The findings suggest that regulatory authorities should persist in enforcing the GBGFS policy and encourage corporate R&D investment. In addition, the central government should design targeted policies based on the characteristics of different regions to improve the policy effect. • The Chinese authorities implemented the GBGFS on August 31, 2016. • The GBGFS effectively promotes EF firms' TFP (this result is robust). • The policy effect gradually expanded as the GBGFS was enforced over time. • The policy effect becomes significant when R&D, ROA and GSF exceed certain values. • The GBGFS has a greater impact in more developed region than less developed regions.
