摘要/Abstract

摘要： 在不同类型产业集聚背景下,探索长三角地区数字经济发展对于碳排放效率的影响具有重要的理论与现实意义。基于2011—2021年长三角地区城市面板数据,以专业化产业集聚和多样化产业集聚为门槛变量,构建系统广义矩估计模型、动态门槛模型,深入考察长三角地区数字经济发展对碳排放效率的影响。研究发现,长三角地区数字经济发展对提高碳排放效率具有促进作用,但该促进作用在不同类型产业集聚下存在显著差异。长三角地区数字经济发展对碳排放效率的影响在专业化产业集聚下存在单一门槛效应,即当专业化产业集聚水平较低时,数字经济发展对碳排放效率产生负向影响;当专业化产业集聚水平越过门槛值后,数字经济发展对碳排放效率产生正向影响。长三角地区数字经济发展对碳排放效率的影响在多样化产业集聚下存在双重门槛效应,即当多样化产业集聚水平低于第一个门槛值时,数字经济发展抑制碳排放效率提升;当多样化产业集聚水平高于第一个门槛值但是低于第二个门槛值时,数字经济发展抑制碳排放效率提升的作用有所减弱;当多样化产业集聚水平高于第二个门槛值时,数字经济发展能够促进碳排放效率提升。因此,长三角地区政府应根据实际情况加大数字经济发展力度,合理规划地区专业化和多元化产业集聚规模,从而更好地利用数字经济提高碳排放效率。

Abstract: In the context of different types of industrial agglomeration, exploring the impact of the development of the digital economy on carbon emission efficiency in the Yangtze River Delta region holds crucial theoretical and practical significance. Based on the city panel data in the Yangtze River Delta region from 2011 to 2021, and taking the specialized industry agglomeration and diversified industry agglomeration as threshold variables, this paper constructs a systematic generalized moment estimation model and a dynamic threshold model to conduct an in-depth investigation into the impact of digital economy development on carbon emission efficiency in the Yangtze River Delta region. The findings show that the development of the digital economy in the Yangtze River Delta region exerts a promoting effect on enhancing carbon emission efficiency. However, the promoting effect significantly varies under different types of industrial agglomeration. The impact of digital economy development on carbon emission efficiency in the Yangtze River Delta region has a single threshold effect under specialized industrial agglomeration, that is, when the level of specialized industrial agglomeration is low, the development of digital economy has a negative impact on carbon emission efficiency. When the concentration level of specialized industries crosses the threshold value, the digital economy development has a positive impact on carbon emission efficiency. The impact of digital economy development on carbon emission efficiency in the Yangtze River Delta region has a dual threshold effect under diversified industrial agglomeration, that is, when the level of diversified industrial agglomeration is lower than the first threshold value, the development of digital economy inhibits the improvement of carbon emission efficiency; when the level of diversified industrial agglomeration is higher than the first threshold value but lower than the second threshold value, the role of digital economy development in suppressing the improvement of carbon emission efficiency is weakened. When the level of diversified industrial agglomeration exceeds the second threshold value, the development of the digital economy can promote the improvement of carbon emission efficiency. Therefore, the governments in the Yangtze River Delta region should increase their efforts in developing the digital economy based on the actual situation, plan the scale of regional specialization and diversified industrial agglomeration reasonably, and better utilize the digital economy to improve carbon emission efficiency.

Key words: digital economy development, carbon emission efficiency, Yangtze River Delta region, industrial agglomeration, threshold effect
