Based on an extended three-step CDM model, this paper addresses the impacts of research and development (R&D) and information and communication technology (ICT) on firm productivity for the World Bank innovation survey data of China. The study includes ICT investment and R&D as the two main inputs into innovation and productivity. We find that R&D and ICT investments positively affect product innovation and process innovation, with R&D being more important for innovation and productivity, and ICT being more important for innovation and no direct effect on productivity. We conclude that R&D and ICT investments increase the probability of product innovation and process innovation, which increase firm's productivity, suggesting that R&D and ICT investments indirectly affect productivity through innovation.

The digital economy has become important in the world's major economies. Improving energy efficiency is the key to achieving stable and sustainable economic growth and carbon emissions reduction. However, the impact of the digital economy on energy efficiency remains unclear. Accordingly, this study examines the relationship between the digital economy and energy efficiency from the Environmental Kuznets Curve (EKC) perspective. In doing so, this study confirms that the digital economy follows the EKC in energy utilization efficiency, and there is a U-shaped relationship between the digital economy and energy efficiency, although this relationship differs from one region to another. This study also discusses the moderating effects of environmental regulation and innovation capability in this U-shaped relationship, confirming that they have a moderating effect on this relationship, reducing the inflection point of the U-shaped relationship, and reducing the negative influence of the digital economy on the energy efficiency and enhancing the positive impact. This study can serve as a reference for policymakers and professionals in emerging economies, helping them achieve a win-win situation for economic development and reducing carbon emissions.

Chief executive officers (C.E.O.s) play a dominant role in firm decision-makings and operations, and their characteristics will affect firm sustainable growth. This study investigates whether C.E.O. academic experience affects firm sustainable growth. Using a sample from China, we find that C.E.O. academic experience is positively related to firm sustainable growth, and the effect is pronounced for high-tech firms. Further analyses demonstrate that the results are robust to alternative measures and controlling for endogeneity problems. Finally, the channel analysis shows that the effect is partially driven by firm innovation and internal control. [ABSTRACT FROM AUTHOR]
