New Research Highlights Importance of Investment in New Infrastructure for Economic Development and Technological Innovation

Research presented in a new study from Liaoning University emphasizes the significance of investment in new infrastructure supported by information technology for the economic development and technological innovation of developing countries. The study employed a comprehensive index of China's sustainable innovation ecosystem and established a spatial Durbin panel regression model to empirically test the spatial spillover effect of new infrastructure investment. The findings indicate that new infrastructure investment has a positive impact on the sustainability of regional innovation ecosystems.

Key Takeaways:

• The study used panel data from 31 provinces and cities in China from 2010 to 2023 to analyze the impact of new infrastructure investment on sustainable innovation ecosystems.
• The research found that for every 1% increase in new infrastructure investment under the neighborhood matrix, economic matrix, and geographic matrix, the comprehensive index of the sustainable innovation ecosystem increases by 0.049%, 0.022%, and 0.060%, respectively.
• The study identified two important pathways through which new infrastructure investment enhances the sustainability of regional innovation ecosystems: R&D capital agglomeration and human capital agglomeration.
• The research concluded that public investments in education, social security, and environmental protection have a positive moderating effect on the sustainability of new infrastructure investment and innovation ecosystems.
• The study is an interesting topic with reference value for enhancing the sustainability of innovation ecosystems in developing countries.
• The research was conducted by Zhian Yang from the School of Economics at Liaoning University, and additional authors include Pingzhang Lv.
