RESEARCH ON THE IMPACT OF TECHNOLOGICAL INNOVATION ON CARBON EMISSION INTENSITY: EMPIRICAL ANALYSIS BASED ON CHINESE PROVINCIAL PANEL DATA

Abstract

Accelerating technological innovation and constructing a green and low-carbon economic development system is crucial for China to realize carbon emission reduction and then reach the goal of "double carbon"。 Utilizing data from 30 provinces in China spanning 2005 to 2019, this study examines the influence of technological innovation on carbon emission intensity. This investigation employs the STIRPAT model in conjunction with a spatial econometric model. Furthermore, the study introduces an upgraded industrial structure, selecting three key dimensions—rationalization, advancement, and ecology—to assess the industrial structure's level holistically. The objective is to delve into its mediating role between technological innovation and carbon emission intensity. The study's findings indicate that technological innovation markedly curtails carbon emission intensity. The upgraded industrial structure serves as a partial mediator between the two, with the advanced industrial structure exhibiting the most profound impact. Additionally, the regional carbon emission intensity in China displays a notable positive spatial correlation. Moreover, there's a discernible spatial spillover effect associated with technological innovation's influence on carbon emission intensity.
