Quantity or quality? Regional innovation policy and green technology innovation

Mitigating environmental pollution in China: Unlocking the potential for high-quality innovation

“…Zheng et al. 51 revealed that China’s national innovation strategy effectively contributes to technological innovation quantity and quality. Han and Mao 52 showed that intelligent transformation improves innovation quality through human capital, research and development (R&D) expenditure, information sharing, and factor allocation.…”

“…Moreover, current studies have widely examined technological innovation, including green innovation, at the national level, 40 , 59 with a particular focus on China. 46 , 51 However, significant differences exist in ED level, population size, industrial structure, and other factors among different provinces, which may impact the performance of technological innovation. Therefore, this study measures China’s HI among different provinces from innovation environment and output perspectives, demonstrating that HI is an internal driving force for environmental protection and sustainable development in China.…”

Impact of National Innovative City Policy on Enterprise Green Technology Innovation—Mediation Role of Innovation Environment and R&D Investment

“…Measures of green patents granted were the dependent variable, including the total number of green patents (pataut), green invention patents (pataut-invention), and green utility patents (pataut-utility) [15,35]. Compared to patent applications, patents granted are a better indicator of green technological innovation because the innovation quality has been officially certified [36,37]. Invention patents typically embody more significant technological breakthroughs than utility patents, so they can better represent the quality of green innovation [38,39].…”
