The heterogeneous effects of different technological innovations on eco-efficiency: Evidence from 30 China’s provinces

Eco-efficiency (EE) is an important indicator to reflect the level of sustainable economic growth. This article places contribution to the existing literature by examining the relationship between innovation and eco-efficiency by incorporating three different innovation indicators: invention patent,...
