工业智能化、产业集聚与碳生产率

Industrial intelligence,industrial agglomeration,and carbon productivity

本文基于2011-2019年中国30个省份的面板数据测度工业智能化指标,实证检验了工业智能化与碳生产率之间的影响机制。结果显示:工业智能化显著提高了碳生产率,这一结论在进行一系列稳健性检验后仍然成立。机制分析表明,工业智能化主要是通过多元化集聚间接提高碳生产率,由于产业集聚生命周期的存在,工业智能化对碳生产率的影响呈现出“先增后减”的非线性特征。空间计量分析表明,工业智能化不仅可以提高本地的碳生产率,还可以提高邻近地区的碳生产率,有助于形成地区间绿色协调发展的空间格局。异质性分析表明,在非资源依赖、工业化水平高、环境规制强度低的地区,工业智能化提高碳生产率的作用更显著。研究结果为提高碳生产率进而实现“双碳”目标提供了一条可行的路径,也为政府部门积极谋划区域工业智能化战略布局提供了有益的借鉴。

Industrial intelligence with"intelligent manufacturing"as the core has provided a crucial driving force for China to achieve the goal of"carbon peak and carbon neutrality."Based on the panel data of 30 provinces in China from 2011 to 2019,this paper measures the industrial intelligence indicators from three aspects:the basic conditions of intelligence,the degree of intelligent application,and the achievements of intelligent technology,and empirically tests the spatial-temporal evolution characteristics and influence relationship between industrial intelligence and carbon productivity.This paper includes industrial agglomeration into the research framework and expounds on the nonlinear relationship between industrial intelligence and carbon productivity based on the life cycle theory of industrial agglomeration to analyze the influencing mechanism between industrial intelligence,industrial agglomeration,and carbon productivity.In addition,this paper also takes resource dependence,industrialization level,and environmental regulation intensity into consideration to explore whether it has a heterogeneous impact on the relationship between industrial intelligence and carbon productivity,and improve the theoretical framework of the relationship between industrial intelligence and carbon productivity.The results show that industrial intelligence significantly improves carbon productivity.Industrial intelligence promotes diversified agglomeration and specialized agglomeration.But it mainly indirectly improves carbon productivity through diversified agglomeration.Due to the existence of the life cycle of industrial agglomeration,the influence of industrial intelligence on carbon productivity presents a nonlinear feature of"first increase and then decrease."Industrial intelligence can improve carbon productivity not only in local areas but also in neighboring areas,which will be conductive to shape a spatial pattern of coordinated green development among regions.The role of industrial intelligence in promoting carbon productivity is more significant in regions with non-resource dependence,high industrialization levels,and low environmental regulation intensity.The results of this study provide a feasible path to increase carbon productivity and achieve the"double-carbon"goal and also provides a beneficial reference for government departments to plan the strategic layout of regional industrial intelligence energetically.
