Abstract
Technological innovation is regarded as an important means to improve carbon efficiency. However, there is no consensus on this view. Meanwhile, few studies have considered how technological innovation affects carbon efficiency. To this end, this study investigates the influencing mechanism and effects of technological innovation on carbon emission efficiency from the perspectives of industrial restructuring and R&D element flow. It establishes the influencing and mechanism model and then deeply studies the impact and paths of technological innovation on carbon emission efficiency, using panel data from 30 provinces in 1999-2020. Results show that (1) technological innovation improves carbon emission efficiency. (2) Regional differences in the impact effects of technological innovation are evident, with a greater contribution to carbon emission efficiency in eastern region. (3) Innovation improves carbon efficiency through two paths: advanced industrial structure and industrial structure rationalization. (4) The moderating effect demonstrates that the technological innovation's influence is gradually enhanced with the interregional mobility of R&D personnel and capital. Hence, decision-makers should correctly guide the orderly flow of R&D factors and further improve the carbon emission reduction effect by increasing innovation support and helping optimize the industrial structure.
