This paper reviews the literature on environmental innovation (EI) and systematizes it by means of an original methodology identifying the main directions in which the literature on EI has developed over time. In order to do so, two algorithms are adopted and used to analyze a citation network...

This paper investigates the optimal environmental policy (the mix of emissions tax and R&D subsidy) when two firms, producing differentiated products, compete in the output market over time. Firms compete over supply schedules, which encompasses a continuum of market structures from Bertrand to...

This paper introduces the evolving understanding and conceptualization of innovation process models. From the discussion of different approaches towards the innovation process understanding and modeling two types of approaches to the evolution of innovation models are developed and discussed....

Using a world multi-sectoral, multi-regional trade model, this paper has investigated the economic and environmental implications of climate control coalitions cooperating on R&D investment that triggers low cost environmentally friendly technologies. We start with the Kyoto scenario where all...

Over the last century and a half, global technological leadership has shifted from Great Britain to the United States. In this paper we argue that China is positioning itself to assume global leadership in technology within the coming few decades. We identify three sources of competitive...

The literature on environmental R&D frequently studies innovation as a two-stage process, with a single R&D event leading from a conventional polluting technology to a perfectly clean backstop. We allow for uncertainty in innovation in that the new technology may turn out to generate a new...

We study the optimal R&D trajectory in a setting where new technologies are never perfect backstops in the sense that there is no perfectly clean technology that eventually solves the pollution problem once and for all. New technologies have stings attached, i.e. each emits a specific stock...

This study considers spatial and nonlinear perspectives to examine the heterogeneous role of green technology innovation in the economic development and air quality of Chinese cities. We find that green inventive technology innovation benefits economic development and air quality improvement,...

The original intention of the government was to provide financial subsidies to firms by implementing innovation support policies. In turn, this will encourage these firms to carry out technological innovation activities. However, there are still differing views in the academic community on...
