重污染企业技术创新与减污降碳耦合协调研究

在“双碳”背景下，通过测度企业技术创新与减污降碳之间的耦合协调关系，并在此基础上通过面板向量自回归模型进一步探究其耦合协调的影响因素，以厘清重污染企业协调发展的现状。实证结果表明，技术创新与减污降碳耦合协调度的变动主要取决于企业技术创新水平，2012—2021年的耦合协调度整体在勉强协调和中级协调间浮动，主要集中在初级协调阶段，其耦合协调效应良好。环境规制和数字化程度对耦合协调度的影响显著为正，能够促进耦合协调发展。

Research on Coupling Coordination Between Technology Innovation and Carbon Reduction in Heavy Polluting

Under the background of "dual carbon", the coupling and coordination relationship between enterprise technological innovation and pollution reduction and carbon reduction were measured. On this basis, the influencing factors of the coupling and coordination through panel vector autoregressive model were further explored, so as to clarify the current situation of the coordinated development of heavy polluting enterprises. The empirical results show that the change of coupling coordination degree between technological innovation and carbon reduction mainly depends on the level of technological innovation of enterprises. From 2012 to 2021, the coupling coordination degree fluctuates between the reluctant coordination and the intermediate coordination, mainly concentrates in the primary coordination stage, and the coupling coordination effect is good. The influence of environmental regulation and digitization degree on coupling coordination degree is significantly positive, which can promote the development of coupling coordination.
