A STUDY OF THE IMPACT OF LAND USE CHANGE AND THE DIGITAL ECONOMY ON GREEN INNOVATION IN 30 CHINESE PROVINCES, 2013-2022

Green Innovation (GI) is an inevitable choice to achieve sustainable development under the dual carbon target.In the context of the "dual-carbon" strategy, there is an urgent need to clarify how the digital economy and land-use change can synergize to drive green innovation in order to break the dual dilemma of unbalanced regional development and resource and environmental constraints.This study utilizes the Super-SBM (Super-Slack-Based Measure) model to assess green innovation (GI) from 2013 to 2022.Using the Spatial Durbin Model, it reveals the impact of digital economy and land use on GI, and draws the following conclusions: (1) China's regional average GI index is at a low to medium level, but it shows a gradual upward trend with obvious regional differences.There is a decreasing trend from southeast to northwest.(2) The GI of each region shows obvious agglomeration, and some regions show polarization and return effects.(3) The spatial conduction effect is significant.Land use change has obvious direct negative effect on GI, and indirect effect offsets part of the direct effect, resulting in the overall effect is not significant.Digital economy has an obvious direct positive effect on GI, but the indirect negative effect is stronger, resulting in a negative overall effect and a more obvious interregional spatial spillover effect.
