| As the human living environment continues to deteriorate,more and more countries have elevated "carbon neutrality" to a national strategy and put forward a vision of a carbon-free future.In this context,China has proposed the goals of "carbon peaking" and "carbon neutrality" based on the inherent economic transformation and development needs.The proposed "double carbon" target has an important impact on China’s economic development;the realization of the "double carbon" target should also be considered from the perspective of the development of the whole society.Since the reform and opening up,the total economic volume of China has been growing,and the overall strength of the country is strong,laying a solid economic foundation for the low-carbon goal of energy conservation and emission reduction.In order to achieve the goal of "double carbon",China should seek a greener,sustainable and inclusive economic growth.Green production can balance economic development and environmental protection,and the current rough economic growth in China is no longer in line with the development of the times,in order to achieve the goal of sustainable development should vigorously carry out green production activities,and improve green total factor productivity.In recent years,China has been deepening its reform,increasing its openness and encouraging enterprises to "go global".With the support and guidance of the government,Chinese enterprises have gone abroad and outward direct investment has developed rapidly.However,there is a lack of research on the impact of international investment on green total factor productivity from the perspective of "double carbon" target.The structure of this thesis is in five parts,the first chapter is the introduction,which discusses the research background and significance,literature review,research content and methodology,and the innovation point of this thesis respectively.The second chapter is the impact mechanism,using a combination of theory and practice to systematically analyze the theoretical impact mechanism of OFDI,which affects green total factor productivity through technology spillover effect,environmental effect and industrial structure effect.Chapter 3elaborates the characteristics of OFDI development in China,and also adopts provincial panel data to measure China’s green total factor productivity through SBM-GML model,which reflects the real level of green development in China more comprehensively.The fourth chapter is the empirical part,constructing a regression model to empirically prove the impact of OFDI on China’s green total factor productivity research analysis.Examining OFDI from the perspective of regional heterogeneity,the empirical results show that OFDI can significantly increase the level of green total factor productivity,and every 1% increase in OFDI green total factor productivity increases by 0.204% accordingly.Through further mechanism testing,the results confirm that the theoretical influence mechanism of OFDI is reasonable.Chapter 5 is the conclusion and recommendation,which proposes feasible suggestions through the previous study,in order to provide empirical reference to promote the realization of "double carbon" goal and green sustainable development under the new economic normal. |
