Corporate green-technology innovation (GTI), an inevitable choice for sustainable development in China and the world, has attracted widespread attention in academic circles. However, prior studies have ignored the critical impact of informal institutions on GTI. The present study introduces the concept of regional integrity, as an important informal institution. It analyzes whether, how, and the extent to which levels of regional integrity can influence GTI in firms. Based on data derived from people known to have defaulted on orders issued by the Supreme People's Court and green patent-licensing data from listed companies between 2013 and 2020, we show that a decline in regional integrity levels can significantly inhibit GTI. We use instrumental-variable method to overcome a potential endogeneity problem; after a series of robustness tests, the conclusions remain valid. Further analysis shows that lower levels of regional integrity can hinder corporate GTI by reducing the willingness of firms to disclose environmental information and diminishing the impact of environmental regulations. We also find that, for firms whose directors and general managers do not hold concurrent posts, state-owned firms, and utility patents, lower levels of regional integrity have a more significant inhibitory effect on GTI.

Economic development and ongoing urbanization are usually accompanied by severe haze pollution. Revealing the spatial and temporal evolution of haze pollution can provide a powerful tool for formulating sustainable development policies. Previous studies mostly discuss the differences in the level of PM2.5 among regions, but have paid little attention to the change rules of such differences and their clustering patterns over long periods. Therefore, from the perspective of club convergence, this study employs the log t regression test and club clustering algorithm proposed by Phillips and Sul (Econometrica 75(6):1771–1855, 2007. 10.1111/j.1468-0262.2007.00811.x) to empirically examine the convergence characteristics of PM2.5 concentrations in Chinese cities from 1998 to 2016. This study found that there was no evidence of full panel convergence, but supported one divergent group and eleven convergence clubs with large differences in mean PM2.5 concentrations and growth rates. The geographical distribution of these clubs showed significant spatial dependence. In addition, certain meteorological and socio-economic factors predominantly determined the convergence club for each city. [ABSTRACT FROM AUTHOR]

This paper uses the number of green patents granted of listed companies and the number of fintech companies in prefecture‐level cities in China from 2011 to 2018 to investigate the impact of fintech development on corporate green technology innovation and its mechanisms. We find that fintech can significantly promote corporate green technology innovation. Specifically, the promotion effect of fintech works through three channels: alleviating financing constraints, gathering scientific and technological talents, and optimizing environmental regulations. Heterogeneity tests find that its promotion effect is more significant for the eastern region, invention patents, state‐owned enterprises, and low environmental uncertainty. [ABSTRACT FROM AUTHOR]

As the economy enters the new normal in China, more and more intellectuals are concerned about the energy consumption in the economic green transformation and development process; this article computes the energy consumption embodied in various final demand types by the utilization of the environmentally extended input-output (EEIO) model during 2000–2014. Then, the structural decomposition analysis is adopted for exploring energy consumption changes' driving factors considering various final demand categories. Furthermore, the decoupling between economic growth and energy consumption embodied in various final demand categories is revealed by the application of the Tapio model in China. The results indicate as below: (1) the energy consumption embodied in various final demand categories increased significantly during the study period; (2) the gross fixed capital formation (GFCF) was most conducive to the growth of energy consumption, while the construction department emerged as the greatest energy user in GFCF; (3) coal and oil were two main energy sources consumed regardless of any final demand categories; (4) in the three drivers, the scale effect had a primary contribution to increasing energy consumption. The intensity effect made a crucial contribution to mitigating energy consumption. The structural effect had a mild contribution to the energy consumption changes; (5) the five final demand categories were roughly characterized by the weak decoupling over the period 2000–2014. GFCF determined the decoupling index between economy growth and energy consumption largely. Finally, this article put forward implied policies concerning the reduction of energy utilization in China.

To address global climate change, achieving carbon peak and carbon neutrality has become a global consensus. However, the means to simultaneously achieve carbon reduction and promote green economic development, particularly in developing countries, require further investigation. This study evaluates the impact of e-commerce on CO 2 emissions. Through an examination of the effects of the National E-Commerce Demonstration City (NEDC) policy from 2006 to 2017, this paper reveals that e-commerce growth facilitated by the NEDC policy resulted in a 7.89% reduction in total CO 2 emissions and a per capita reduction of 1.1146 tons in the pilot cities. Mechanism analysis demonstrates that the upgrading of industrial structure, development of digital finance, and the growth of innovation and entrepreneurship serve as primary pathways for this impact. The robustness of the findings is supported by parallel trend tests, placebo tests, and additional sensitivity analyses. Furthermore, the research reveals that the NEDC policy exhibits a more significant reduction in CO 2 emissions in cities with higher levels of economic development and non-resource-based cities. Welfare analyses show that the NEDC policy has significant socio-economic effects. These findings provide new evidence on the environmental effects of the digital economy and offer insights into achieving carbon neutrality. • The National E-commerce Demonstration Cities (NEDC) policy reduced CO 2 emissions. • Optimizing industrial structure, enhancing digital finance, and promoting innovation and entrepreneurship are mechanisms. • The effect is more pronounced in cities with high economic levels and high resource dependence. • The NEDC policy substantially enhanced social welfare by reducing CO 2 emissions.
