数字经济驱动绿色低碳产业发展——基于中介效应模型分析
Digital Economy Drives the Development of Green and Low-Carbon Industries—Based on the Analysis of Intermediary Effect Model

“双碳”目标的实现离不开低碳产业的发展，而数字经济在助力企业实现低碳转型的过程中发挥着重要作用。本文通过运用2011~2020年中国31个省级面板数据建立模型，通过熵权法对指标进行客观赋权并计算数字经济和低碳产业的发展水平，分析我国数字经济与低碳产业的发展情况，并验证数字经济对低碳产业发展的驱动效应和中介效应，最后通过模型的内生性检验和稳健性检验来确保结果的准确性。研究与分析结果表明，从整体上看，我国省级数字经济和低碳产业发展水平在2011~2020年间均呈现上升趋势；在回归分析中，数字经济对低碳产业发展具有明显的正向驱动作用；在中介效应中，本文通过数字科技发展这个中介效应可以有效推动低碳产业的发展。因此，根据这些结论，要重视科技的发展，加强数字经济对低碳产业的驱动作用，推动经济社会的绿色、低碳和可持续发展。
The realization of “double carbon” goal can not be separated from the development of low-carbon industry, and the digital economy plays an important role in helping enterprises to achieve low-carbon transformation. This paper uses the panel data of 31 provincial levels in China from 2011 to 2020 to establish a model, uses the entropy method to objectively empower the indicators and calculate the development level of digital economy and low-carbon industry, analyzes the development of digital economy and low-carbon industry in China, and verifies the driving effect and intermediary effect of digital economy on the development of low-carbon industry. Finally, the endogeneity and robustness of the model are tested to ensure the accuracy of the results. The research and analysis results show that, on the whole, the development level of digital economy and low-carbon industry at the provincial level in China shows an upward trend from 2011 to 2020. In the regression analysis, digital economy has a significant positive driving effect on the development of low-carbon industry. In the intermediary effect, this paper can effectively promote the development of low-carbon industry through the intermediary effect of digital technology. Therefore, according to these conclusions, we should attach importance to the development of science and technology, strengthen the driving role of digital economy in low-carbon industries, and promote the green, low-carbon and sustainable development of economy and society.
