Green development is an essential requirement for the high-quality development. In the context of the new round of technological revolution, the digital economy has injected new momentum into China's high-quality economic development. This article aims to clarify the relationships among digital economy, green innovation, and green development using Westerlund and Edgerton (2007) cointegration test as well as pooled mean group (PMG) estimation and utilizing yearly data from 274 cities in China from 2011 to 2019. Overall, the results confirm the existence of cointegration relationships between green development and green innovation, between green development and digital economy, as well as between digital economy and green innovation, and support that digital economy and green innovation can affect the green development in the long-term positively. Additionally, while digital economy positively affects the green development in the short-run, green innovation cannot affect the green development. Furthermore, while the long-run positive impact of digital economy and green innovation on green development is generally established among eastern, central, and western regions, the short-run impact of such two factors on green innovation varies among different regions, seeing as both two variables exert no significant impact on green development in western region. Empirical findings offer important policy implications for the policymakers to attach more importance on the emerging economy model such as digital economy or green innovation, which can bring about long-term green development.

This research explores the impact of monetary policy on the growth rate of total factor productivity (TFPG) and innovation efficiency (IE) through panel data of 30 countries from 1983 to 2018 by the bias-corrected fixed-effect dynamic (BCFE) model. We find that tight monetary policy negatively impacts the growth rate of total factor productivity (TFPG) and innovation efficiency (IE), which is still valid after a series of robustness tests. We then perform sub-sample regressions, and the results show that countries with higher government efficiency, higher financial development, and stricter environmental policy can reduce the negative impact of tightening monetary policy on total factor productivity and innovation efficiency. Our research illustrates that a tightening monetary policy not only adversely impacts total factor productivity but also influences the main driving force of its growth-innovation efficiency.

Renewable energy development is essential to energy structure transition and environmental emission reduction, and promoting renewable energy development via green financial instruments has been an effective approach to attain the objective of carbon neutrality in China. This research explores the bi-directional cointegration relationship between green finance and renewable energy development by adopting provincial data of China from 2005 to 2018. Results indicate a long-run bi-directional comovement exist between green finance and renewable energy development. This cointegration relationship appears in the eastern and central provinces of China, but is absent for western provinces. The pooled mean group estimators show that green finance cannot promote renewable energy development in the short run, whereas it does so in the long run for both the eastern and central provinces. Our research presents implications for emerging economies to initiate and design green financial instruments and renewable energy measures. [ABSTRACT FROM AUTHOR]

Countries around the world are facing enormous challenges in their economic and social development as COVID‐19 continues to spread, resulting in slower economic recovery in the post‐pandemic era. Considering the impact of economic growth on future sustainable development in this new era, green economic recovery (GER) can achieve a win‐win situation between economic recovery and environmental improvement and bring forth environmentally sustainable economic growth. This research first lists related COVID‐19 literature surveys and GER policies in the post‐pandemic era in China. Based on a comparative study of the international experience of GER policy practices, this paper then analyzes the opportunities and challenges China faces for GER and puts forward countermeasures and suggestions on how to promote its sustainable development in the post‐epidemic era. We believe our research presents useful enlightenments for sustainable economic and social development in the post‐epidemic era. [ABSTRACT FROM AUTHOR]

This study first investigates different types of sanctions on energy security by employing data from a panel of target countries covering the period 1996–2014 and using the panel fixed effect model. Our evidence indicates that international sanctions do significantly negatively influence the energy security of target countries in some cases. Specifically, unilateral sanctions, U.S. sanctions, economic sanctions, and the intensity of sanctions have a significantly negative impact on energy security. However, plurilateral sanctions, EU sanctions, UN sanctions, and non-economic sanctions have no significant impact on the energy security of target countries. The results of endogeneity concerns are also consistent with the results of the basic regression analysis. Overall, our empirical findings merit particular attention from policy makers of target countries to ensure their energy security when facing international sanctions. [ABSTRACT FROM AUTHOR]
