| The world is experiencing unprecedented changes in a century.The new round of technological revolution and industrial transformation will become the main force in reshaping the global competitive landscape.Strategic emerging industries represent the direction of the new round of technological revolution and industrial transformation,and as an important component of high-quality economic development,they are leading the future economic development.As the world’s largest carbon dioxide emitter,achieving the dual carbon target in China is a long-term process,facing pressure from various aspects.Many studies have shown that low-carbon economic development has led to the emergence of strategic emerging industries,and the development of strategic emerging industries has made low-carbon economic development possible.Therefore,what role does the current strategic emerging industry cluster development play and what impact it has on the carbon emission intensity of each province is an urgent issue with important research value.In order to clarify the impact of strategic emerging industry agglomeration on carbon emission intensity,theoretical analysis and empirical research were carried out based on previous research and panel data of 30 provinces in China from 2009 to 2020.In Chapter 1,this article mainly reviews the relevant literature on the development of strategic emerging industries and carbon emissions.In Chapter 2,starting from the path and process of the impact of strategic emerging industry clusters on carbon emission intensity,the internal theoretical mechanism of their impact is analyzed in detail,and it is proposed that with the development of strategic emerging industry clusters,carbon emission intensity is likely to rise first and then decline.In Chapter 3,based on the measured data on the agglomeration degree and carbon emission intensity of strategic emerging industries,the development status of regional strategic emerging industry agglomeration and carbon emission intensity is analyzed.It is found that the development of strategic emerging industries in regions with a good development foundation is faster,and the gap between the development of strategic emerging industries across regions is further widened.China’s carbon emission intensity is decreasing year by year,But there is still much room for decline;Further,by measuring the Moran Index and testing the spatial correlation between strategic emerging industry clusters and carbon emission intensity,it is found that both provincial strategic emerging industry clusters and carbon emission intensity present significant positive spatial autocorrelation,and there is a significant negative spatial correlation between strategic emerging industry clusters and carbon emission intensity.In Chapter 4,this article expands and improves the STIRPAT model for the first time from the perspective of strategic emerging industry agglomeration,and considers the spatial correlation of carbon emission intensity.It constructs an expanded STIRPAT model that includes spatial effects to explore the spatial effects of strategic emerging industry agglomeration on carbon emission intensity.The empirical results show that carbon emission intensity has a positive spatial spillover effect,That is,the carbon emission intensity of a region is positively affected by the carbon emission intensity of adjacent regions;The impact of strategic emerging industry agglomeration on carbon emission intensity presents an "inverted U-shaped" relationship,that is,with the improvement of the level of strategic emerging industry agglomeration,carbon emission intensity shows a trend of first rising and then falling;When the agglomeration degree of strategic emerging industries in adjacent regions is low,the spatial spillover effect on carbon emission intensity is not significant,but when the agglomeration degree of strategic emerging industries in adjacent regions reaches a certain level,there is a positive spatial spillover effect on carbon emission intensity.In Chapter 5,we construct a panel threshold model using the level of economic development and the degree of agglomeration of strategic emerging industries as threshold variables for the first time to explore the threshold effect of strategic emerging industry agglomeration on carbon emission intensity,and further confirm whether there is a "inflection point" in the impact of strategic emerging industry agglomeration on carbon emission intensity,causing a sudden change in the direction of impact,The empirical results show that: when the concentration degree of strategic emerging industries is lower than the threshold value,the increase in the concentration degree of strategic emerging industries will lead to an increase in carbon emission intensity,while when the concentration degree of strategic emerging industries is higher than the threshold value,the increase in the concentration degree of strategic emerging industries will reduce carbon emission intensity;When the level of economic development is lower than the threshold value,the increase in the degree of agglomeration of strategic emerging industries will lead to a significant improvement in carbon emission intensity.When the level of economic development is higher than the threshold value,the impact of strategic emerging industry agglomeration on carbon emission intensity is not significant.Based on the research conclusions,the main recommendations are as follows:strengthen interregional cooperation,promote low-carbon economic development,and reduce carbon emission intensity;Formulate carbon emission reduction policies based on regional development status and local conditions;Differentiation promotes the development of strategic emerging industry clusters based on regional economic development and the foundation of strategic emerging industry clusters. |
