制造业转型升级视角下数字经济与绿色技术创新绩效研究

Research on Digital Economy and Green Technology Innovation from the Perspective of Manufacturing Transformation and Upgrading

摘要:

在创新驱动和数字经济发展的大背景下，本文重点关注数字经济与绿色技术创新之间存在的内在联系。利用2011~2019年中国280个地级市的面板数据，通过固定效应模型、中介效应模型等探讨了数字经济对绿色技术创新的影响效果及传导机理。研究发现：数字经济通过禀赋效应、赋能效应、治理效应和社会效应对绿色技术创新产生直接影响，该结论在经过内生性和稳健性检验后依然成立；机制检验表明，数字经济还可以通过制造业要素密集转型升级和制造业污染密集转型升级间接促进绿色技术创新。此外，数字经济对绿色技术创新的影响具有异质性，东部地区的促进效果显著大于中西部地区，且在数字经济和绿色技术创新发展先进的城市的促进作用远大于落后的城市。因此，本文的研究有利于促进绿色技术创新，缩小区域间绿色技术创新差距，实现中国经济提质增效与转型升级。

Abstract:

Under the background of innovation-driven and digital economy development, this paper focuses on the internal relationship between the digital economy and green technology innovation. Using panel data of 280 prefecture-level cities in China from 2011 to 2019, this paper studies the influence and mechanism of the digital economy on green technology innovation through the fixed-effect model, mediating effect model. We find that the digital economy can directly promote the progress of green technology innovation capability and indirectly improve green technology innovation ability through transformation and upgrading the factor-intensive and pollution-intensive manufacturing sector. This conclusion is still valid after endogeneity and robustness tests. We also find that the heterogeneous effect of the digital economy on green technology innovation across regions. The impacts on the eastern regions are significantly greater than those in the central and western regions. In addition, cities with advanced digital economy and green technology innovation play a much greater role in promoting digital economy and green technology innovation than backward cities. Our study provides policy implications on coordinating and promoting the development of regional green innovation and narrowing the gap of regional green innovation.
