Study on the evolution of green innovation city network and its carbon emission effect in Yellow River Basin cities

Against the background of increasing urbanization rate and intensifying global warming, conflicts between humans and the natural environment continue to arise, and regionalized forms of spatial organization have become an important research direction. This paper constructs a green innovation city network. It empirically tests the evolution process of the green innovation city network and its carbon emission effect by combining the social network approach and the spatial Durbin model. The conclusions are as follows: (1) the strong ties among green innovation city networks are mainly distributed in and around the provincial capital cities and the middle and lower reaches of the Yellow River Basin; the density of green innovation city networks has been strengthened, and the degree centrality and closeness centrality have been improved. (2) The carbon emissions of cities in the Yellow River Basin are generally increasing. Still, the rate of increase is slowing down. The carbon emissions from liquefied petroleum gas show a decreasing trend yearly, and the energy structure tends to improve. (3) The impact of the green innovation city network on carbon emissions mainly comes from its externality's direct and indirect effects; the increase of degree centrality will reduce the total carbon emissions in the region and the network-associated regions.

Complementarity Between Investment in Information Technology (IT) and IT Human Resources: Implications for Different Types of Firm Innovation

Innovation is an important means by which firms generate new revenue streams for topline growth. Given the information intensity of innovation, a key question that managers face is: How do we organize our IT-related resource investments to promote innovation performance? This is a consequential question because different types of innovation incur varying levels of upside potential, failure risk and investment costs. In this research, we aim to answer this question by distinguishing four types of innovations—incremental, radical, non-IT related and IT related—that firms aim to produce and examining the extent to which each of these types benefits from complementary investments in IT human resources and IT compared with either type of investment alone. Using patent data from the U.S. Patent and Trademark Office, our analysis of 36,812 firm-year observations reveals that complementary investments in IT human resources and IT are associated with a 117% increase in incremental innovation, a 155% increase in radical innovation, a 173% increase in non–IT-related innovation and a 161% increase in IT-related innovation. The results of this study can be helpful in enabling managers to make informed decisions about how to organize and get the most out of their resource investments based on their innovation objectives.
