Green technology innovation is an effective way to overcome the constraints of combining resources and environment. This paper focuses on the impacts of media attention and corporate environmental information disclosure on green technology innovation of China’s 487 listed heavily polluting companies from 2007 to 2019. The corporate environmental information disclosure was measured using text analytics and data mining and considering the impacts of political connections. The results indicate that: (1) both positive and negative media attention and the quality of environmental information disclosure significantly contribute to corporate green technology innovation, with negative media attention having a more substantial impact than positive media attention; (2) The environmental information disclosure of China’s heavily polluting industries acts as a mediator in the impact of negative media attention on enterprise green technology innovation; (3) Political connection as a moderating factor has a major suppressive impact on the mediating model. This paper enriches the research relevant to the drivers of green technology innovation in enterprises. It also provides new ideas for exploring the research on the influence on green technology innovation behavior from the perspective of political connections.

We examine the driving effects of various factors on technological innovation to renewables (TIRES), focusing on a set of 29 provinces in China, and apply a dynamic panel approach. China has become a leading player in research and development spending in renewables, and the dynamic panel estimators we use prove themselves to be suitable in handling the persistent effect on TIRES. The level of TIRES in the previous periods is positively and highly correlated with that in the current period and confirmed the need for a stable and consistent policy support for renewables. Electricity consumption is the most important driver for all renewables and wind energy, but the driving effect was weaker for solar energy and biomass. Research and development intensity is the most important driver for biomass, but is only the second most important driver for all renewables, solar energy and wind energy. Unexpectedly, electricity price has had significant negative impacts on TIRES, which reveals that lowering electricity prices will lead to higher innovation in renewables. The driving effect of renewable energy tariff surcharge subsidy is not significant, which means that Chinese subsidy policy has not played the desired role. The driving effect of installed renewable energy capacity is also minimal, which may be due to the fact that overcapacity will hinder TIRES in China. This paper may help policy-makers and the industry understand how to promote TIRES in China effectively based on these above influential factors.
