数字经济赋能生态福利绩效提升的效应分析

Analysis of the effect of digital economy on the improvement of ecological welfare performance

数字经济发展是加快经济发展方式绿色转型、促进居民福祉提高的重要途径。基于2011—2021年省级面板数据,采用熵值法和SBM模型测度数字经济发展指数与生态福利绩效值,运用Tobit模型和中介效应方法考察了数字经济发展对生态福利绩效的影响及作用机制。结果表明:①数字经济发展显著促进了生态福利绩效提高,稳健性检验后结论依然成立;②异质性分析表明,高数字经济水平组和低数字经济水平组均能促进生态福利绩效提高。此外,数字经济发展能够显著促进东部地区生态福利绩效提高,但对中西部地区并未产生显著影响;③数字经济通过提升经济规模、升级产业结构以及技术创新显著促进了生态福利绩效提高。为此,提出持续推动数字经济发展、加强技术创新、针对中西部地区制定差异化战略等建议,以期为提高中国生态福利绩效提供借鉴和启示。

Digital economy development is an important way to accelerate the green transformation of economic development mode and promote the improvement of residents′well-being.Based on the provincial panel data from 2011 to 2021,this paper measured the digital economy development index and ecological welfare performance value using the entropy value method and SBM model,and exam-ined the impact of digital economy development on ecological welfare performance and the mechanism of its action by using the Tobit model and mediation effect method.The results showed that:①Digital economic development significantly contributed to the improve-ment of ecological welfare performance,and the conclusion still held after the robustness test.②Heterogeneity analysis showed that both the high digital economy level group and the low digital economy level group could promote ecological welfare performance improve-ment.In addition,the development of digital economy could significantly promote the ecological welfare performance improvement in the eastern region,but didn′t have a significant effect on the central and western regions.③The digital economy significantly contributed to the improvement of ecological welfare performance through the enhancement of economic scale,industrial structure upgrading and tech-nological innovation.Therefore,this paper proposed suggestions to continuously promote the development of the digital economy,strengthen technological innovation,and formulate differentiated strategies for the central and western regions,with a view to providing reference and inspiration for the improvement of ecological welfare performance in China.
