摘要:

提升黄河流域城市绿色创新水平是贯彻落实高质量发展战略的重要举措。为探究提高黄河流域城市绿色发展能力的新动能,以2000—2023年黄河流域61个地级市面板数据为样本,系统探讨了数字经济对黄河流域城市绿色创新的赋能效应。结果表明:数字经济对黄河流域城市绿色创新产生显著正向影响,该结论在经过系列内生性和稳健性检验后依旧成立。数字经济分别通过提高地区金融发展水平和人力资本水平进而促进城市绿色创新。数字经济对黄河流域城市绿色创新存在非线性影响,具体地,当产业结构升级由低到高超过门槛值时,数字经济对黄河流域城市绿色创新的作用由负转正。此外,数字经济对黄河流域城市绿色创新的促进作用在黄河中下游地区、非资源型城市和省会(首府)城市更加显著。研究结论揭示了数字经济对黄河流域城市绿色创新的赋能效应,为推动黄河流域绿色化转型与高质量发展提供有益参考。

Abstract:

Improving the green innovation level of cities in the Yellow River Basin is an important measure to implement the high-quality development strategy. In order to explore the new kinetic energy to improve the green development ability of cities in the Yellow River Basin, this paper takes the panel data of 61 prefecture-level cities in the Yellow River Basin from 2000 to 2023 as a sample, and systematically discusses the enabling effect of the digital economy on the green innovation of cities in the Yellow River Basin. The study found that the digital economy has a significant positive impact on urban green innovation in the Yellow River Basin. This conclusion is still valid after a series of endogenous analysis and robustness tests. Mechanism analysis shows that digital economy promotes urban green innovation by improving regional financial development level and human capital level respectively. Further analysis shows that digital economy has a non-linear impact on urban green innovation in the Yellow River Basin. Specifically, when the upgrading of industrial structure exceeds the threshold value from low to high, the effect of digital economy on urban green innovation in the Yellow River Basin changes from negative to positive. In addition, the promotion effect of digital economy on urban green innovation in the Yellow River Basin is more significant in non-resource-based cities and provincial capital cities in the middle and lower reaches of the Yellow River. The research conclusions not only reveal the enabling effect of digital economy on urban green innovation in the Yellow River Basin, but also provide a useful reference for promoting green transformation and high-quality development in the Yellow River Basin.

Key words: digital economy, urban green innovation, Yellow River Basin, threshold effect
