Abstract:
Sustainable material science innovation (MS) is crucial for achieving circular economy goals, but environmental and technological factors influence its effectiveness in responding to economic growth. This study presents a comprehensive macroeconomic-environmental framework for analyzing how economic performance affects MS in various contexts. Utilizing a dynamic Autoregressive Distributed Lag (ARDL) simulation model and global time-series data from 2000 to 2017, we evaluate the moderating effects of plastic waste (PW), eco-technological innovation (ETIN), carbon emissions (CO), and renewable energy consumption (REC). Our results show that GDP has a significant positive effect on MS in both the short and long term. Nonetheless, unmanaged PW diminishes this relationship, whereas ETIN, CO, and REC enhance it. These findings underscore that economic growth alone cannot drive sustainable innovation; it must be supported by effective environmental governance, targeted technological policies, and the integration of renewable energy. By incorporating ecological pressures, technological capacity, and economic performance into a cohesive econometric framework, this research provides new empirical insights into sustainable production systems. The findings inform policies that blend incentives for green R&D, waste valorization strategies, carbon regulation, and renewable energy initiatives to advance Sustainable Development Goals 9, 12, and 13.
