The Penetration of New Generation Information Technology and Sustainable Development of Regional Economy in China—Moderation Effect of Institutional Environment

Sustainable economic development is an important force to enhance the comprehensive national strength. It mainly depends on the breakthrough and innovation of science and technology. The new generation of information technology (NGIT) is the most active field in scientific and technological innovation. It is of great significance to deeply consider the relationship between the new generation of information technology and the sustainable development of a regional economy. In this study, 29 provinces and cities in China from 2009 to 2018 were selected and use the feasible generalized least squares (FGLS) method to empirically analyze the impact of the new generation of information technology on the sustainable development of regional economy. Simultaneously, it analyzes the differences between NGIT and economy sustainable development of the regional economy under different institutional environments. According to the research results, there is a positive correlation between new-generation information technology and the sustainable development of a regional economy. There is a positive U-shaped relationship between the penetration depth of NGIT and the sustainable development of a regional economy. Simultaneously, the higher the institutional environment’s level, the stronger the positive relationship between the penetration of NGIT and the sustainable development of a regional economy.
