制造企业数字化对企业碳排放量的影响研究——基于微观视角的“杰文斯悖论”再检验

Research on the Impact of Digitalization of Manufacturing Enterprises on Corporate Carbon Emissions——A Reexamination of the‘Jevons Paradox’From a Micro Perspective

在“双碳”目标与数字经济时代背景下,有关企业数字化与碳排放关系的研究已然成为当前学术界关注的热点。本文基于2012~2020年我国上市制造企业面板数据,实证研究企业数字化是否有助于降低企业碳排放量,并在此基础上进一步探究企业服务化的调节作用。本文发现:(1)制造企业数字化与企业碳排放总量之间存在“杰文斯悖论”,即企业数字化会增加企业碳排放量,且在一系列稳健性检验与内生性检验基础上结论仍保持高度一致;(2)企业服务化负向调节企业数字化与碳排放量的正向关系,说明企业服务化有助于抑制数字化对碳排放量的促进作用。本文研究结论不仅深刻揭示企业数字化与碳排放之间的复杂关系,丰富企业数字化与企业碳排放方面的相关研究;还进一步拓展企业数字化对企业碳排放的影响机制分析,为制造企业如何基于数字化实践减少碳排放量提供理论指导。

In the era of digital economy,the digitalization of manufacturing enterprises is constantly rising.At the same time,under the background of environmental regulation,manufacturing enterprises are gradually required to reduce carbon emissions.Based on the panel data of China's listed manufacturing enterprises from 2012 to 2020,this paper empirically studies the question that whether the digitalization of manufacturing enterprises is conductive to reduce carbon emissions,and further explores the moderating effect of servitization.The main conclusions of this paper are as follows:(1)digitalization of manufacturing enterprises significantly increases the carbon emissions,and this conclusion remain highly consistent on the basis of a series of robustness tests and endogenous tests.(2)Servitization negatively moderate the relationship between digitalization and carbon emissions.The result of heterogeneity analysis shows that,the relationship between digitalization and carbon emissions may be affected by the differences of element density and ownership.Based on these findings,we put forward some suggestions for manufacturing enterprises on reduce carbon emissions and high-quality development based on digitalization.
