Research on technological progress and carbon emission reduction efficiency in the Yangtze River Delta under carbon neutrality targets
The key factor in improving carbon emission reduction efficiency towards achieving car-bon neutrality goals is of technological progress.In order to conduct a theoretical and practical re-search on the improvement of carbon emission reduction efficiency under the carbon neutrality goals,this article incorporates technological progress into the framework of sustainable develop-ment theory and establishes a dynamic computable general equilibrium(CGE)model for simula-ting and analyzing carbon emission reduction efficiency in the Yangtze River Delta region.The re-search focuses on the impact of sustained investment in technological progress on the dynamic evolution of carbon emission reduction efficiency in the region.The study finds that:① Increas-ing investment in technology can effectively increase the total carbon emission reduction in differ-ent stages in the Yangtze River Delta.In the given scenario,the three provinces and one city in the Yangtze River Delta will invest approximately 8.2 trillion yuan in technology research and de-velopment from 2023 to 2060(based on the 2023 price level),which can achieve a CO2emission reduction of approximately 111 million tons in the region by 2060;② Sustained investment in technological progress has a consistent impact on the dynamic evolution of GDP,carbon emission intensity per unit of GDP,and carbon emission reduction efficiency in the Yangtze River Delta.Especially,the former shows an increasing trend with the continuous injection of funds,the stronger investment,the more robust the incremental development trend;③ Key technological progress in carbon emission reduction can improve the proportion of fossil energy such as coal and oil,while clean energy such as wind and hydro power shows a decreasing trend in all policy sce-narios.The stronger the investment,the more significant the decreasing trend.Technological progress can effectively improve the carbon emission reduction efficiency in the Yangtze River Delta,stimulate endogenous regional economic growth,and is crucial for achieving win-win eco-nomic and environmental objectives.
