Research on regional differences and influencing factors of green technology innovation efficiency of China’s high-tech industry

Effects of Regional Innovation Capability on the Green Technology Efficiency of China’s Manufacturing Industry: Evidence from Listed Companies

“…Economic development provides abundant capital support for the rise of green technology efficiency, and regions with high levels of economic development having higher levels of industrialization and relatively complete environmental policies. Hence, regional GDP was used to measure the level of urban economic development [39]. The cooperation between local and foreign enterprises, and as a result, the knowledge and technology spillover effect in mutual exchange may promote the improvement of production efficiency.…”

“…The improvement of the economic development level will inevitably bring about an increase in government revenue. The government builds a complete green ecology for the manufacturing industry through fiscal and tax policies [39]. The waste treatment rate (WTR) variable was obtained using the entropy method to comprehensively calculate the three indicators of general industrial solid waste: comprehensive utilization rate, centralized treatment rate of the sewage treatment plant, and harmless treatment rate of domestic garbage.…”

Study on the Regional Differences and Promotion Models of Green Technology Innovation Performance in China: Based on Entropy Weight Method and Fuzzy Set-Qualitative Comparative Analysis

“…Second, in terms of GTI efficiency. Liu et al [20] measured the GTI efficiency of China's hightech industrial clusters from input and output. Huang and Wang [21] incorporated environmental pollution in the measurement and investigated the impact of high-speed rail on green innovation efficiency.…”

Measuring Green Innovation Efficiency for China’s High-Tech Manufacturing Industry: A Network DEA Approach

“…Despite a large multitude of literature on innovation efficiency in China's high-tech manufacturing industry, few studies have estimated green innovation efficiency in the high-tech manufacturing industry while considering environmental factors [17,18]. A small fraction of literature did consider environmental pollution when estimating innovation efficiency in the high-tech manufacturing industry, but, in these studies, the overall innovation system was treated as a "black box" without further analyzing the internal structure of the innovation system [19][20][21][22]. Has there been any volatility in green innovation efficiency in China's high-tech manufacturing industry after the implementation of environmental regulations?…”
