Can Sci-Tech Finance Pilot Policies Reduce Carbon Emissions? Evidence From 252 Cities in China

Abstract

It is widely believed that science and technology (sci-tech) finance can pave the way to combat environmental degradation by promoting innovation in environment-related technologies. However, limited research is available to support this argument, and literature is silent on how sci-tech finance pilot policies influence carbon emissions in China. Therefore, this study investigates the impact of technology and financial integration pilot policy (TFIP) on carbon emissions and its dynamic effects, heterogeneity, and mechanisms in 252 cities in China. To do this, the yearly data from 2006 to 2019 were used in the propensity score matching–difference in differences (PSM-DID) method. The results unveiled that 1) the TFIP can effectively reduce the scale and intensity of carbon emissions in pilot cities. The TFIP shows a U-shaped distribution with CO2_Size and CO2_intensity, reaching a minimum in the fifth year. The TFIP has a lagging effect on carbon emissions, which significantly reduces carbon emissions in the second year. The robustness test verifies our conclusion. 2) The heterogeneity test results show that the effect of the TFIP is heterogeneous depending on the spatial and city attributes. The TFIP can effectively reduce carbon emissions in the eastern region and resource-based cities. However, in the central, western, and non-resource–based cities, the reduction effect of the TFIP is not obvious. 3) The impact mechanism finds that the TFIP reduces the scale of carbon emissions by enhancing the green innovation capacity and rationalizing the production structure in the pilot cities. Several policy recommendations are proposed based on the findings such as vigorous development of sci-tech finance to achieve sustainable development of the economy.

“…In addition, another study found that the mechanisms between different pollutant emissions and industrial structure may be completely different, and show a U-shaped, inverted-N-shaped (Kaufmann et al, 1998) or N-shaped (Friedl and Getzner 2003) relationship. Specifically, a study by Ying Lu et al (2022) found that problems with the industrial structure were mainly responsible for environmental deterioration in Northwest China, and a high proportion of the secondary industry will aggravate the pollution of water resources. Zhang et al (2020) used Chinese provincial panel data to prove that a reasonable industrial structure can reduce smog emissions, but the optimization of industrial structure to reduce such pollutant emissions has not been confirmed.…”

“…In 2020, Zhongguancun built China's first STF innovation centre and strived to realise the effective docking of capital and science and technology. However, current research on STF mainly revolves around STF policies and the efficiency of STF, but there are still relatively few analytical methods using networks [11,12]. With the deepening of research on STF and its role in promoting technological innovation, STF has shown new development trends and gradually presented diverse and complex relationships among various subjects.…”
