摘要:

随着区域集聚经济分化的不断加剧,世界环境问题也日益严峻,给各个区域碳减排目标的实现带来了挑战。在此背景下,本文以中国1 384个区县为例,通过实证检验探讨了县域集聚经济分化对碳排放的影响效应。研究发现:①整体而言,集聚经济分化显著提高了中国县域的碳排放水平;②劳动力流动与本地投资激励是集聚经济分化提高中国县域碳排放水平的重要机制;③虽然集聚经济分化提高了中国西部地区的碳排放水平,但却降低了中部与东部地区的碳排放水平。基于上述结论,本文提出以下政策建议:5加快本地产业结构转型升级,推动本地集聚经济分化对碳排放的影响由增排转向减排;②根据不同区域的产业发展阶段制定差异化的区域碳减排战略,以增强或实现集聚经济分化的碳减排作用,最终降低区域的碳排放水平。

Abstract:

The agglomeration economy not only plays an extremely important role in the development process of regional industrialization, but also makes the hierarchical differentiation of the scale of the agglomeration economy between regional economic units increasingly prominent. As the regional agglomeration economies continue to diverge, the world's environmental problems are becoming increasingly severe, which is posing a serious challenge to the achievement of carbon reduction targets in all regions. Given that, by taking China's 1384 counties as an example, this paper explores the effect of county agglomeration economic differentiation on carbon emissions through empirical tests. The results indicate that: ① Overall, agglomeration economic differentiation significantly increases the level of carbon emissions in Chinese counties. ②Labor mobility and local investment incentives are important mechanisms for agglomeration economic differentiation to increase the level of carbon emissions in China's counties.③ Although agglomeration economic differentiation reduces the level of county carbon emissions in central and eastern China, it increases the level of county carbon emissions in western China. In addition, as the agglomeration economic differentiation level rises, the carbon-increasing effect caused by county agglomeration economic differentiation shows an "inverted U-shape" trend. Based on the above conclusions, this paper makes the following policy recommendations:①Local governments should promote the process of taking on technology-intensive or service-oriented low-carbon emission industries in the county, thereby reducing the carbon-increasing effect of the divergence of agglomeration economies. ② In order to enhance or realize the carbon-reducing effect of agglomeration economic differentiation, local governments should formulate complementary industrial development policies in accordance with the characteristics of different regions at the current stage, so as to ultimately reduce the carbon emission level of the region.
