Reviewer #1: Comments on Manuscript “The Impact of Digital Economy on High-quality Economic Development: Research Based on the Consumption Expansion” Thank you very much for giving me the opportunity to review the manuscript.

Studies have found that the digital economy plays a positive role in promoting high-quality economic development. The contemporary economy pursuits the high-quality sustainable development of innovation, coordination, green, openness and sharing. The digital dividends brought by digital economy can well help to promote high-quality economic development. Meanwhile, the digital industrialization and industrial digitalization have spawned new consumer demand and consumption supply modes. It is necessary to analyze the role of consumption expansion in the impact of digital economy on high-quality economic development. Based on Chinese provincial panel data, we first apply the entropy weight method to construct digital economy index and high-quality economic development index. On this basis, it is verified that the development of the digital economy can positively promote the high-quality development of the economy. Then we use the threshold effect model to analyze the role of consumer demand and consumption supply in the digital economy empowering the high-quality development. Regional heterogeneity of this effect is further taken into account. The results dedicate that the digital economy can effectively promote high-quality economic development. This also can be affected by the threshold of consumption expansion, which is manifested in the marginal incremental effect due to the growth of consumption supply. On the contrary, the growth of consumer demand has led to the inverted U-shape of the digital economy to promote high-quality economic development. In the heterogeneity analysis, the threshold effect also varies greatly. The research enriches the theoretical achievements and reveals the impact of consumption expansion on the digital economy affecting the high-quality development, which has certain references for other countries and regions. I have reviewed this paper thoroughly and a few suggestions are given below:

Literature Review:

This section is well-aligned and presents an effective blend of recent and past studies. Overall, this section is appropriate in my opinion. Kindly add some studies in literature review section;

Study design:

This section is well-written and well-explained. Referring to my comments in the Introduction section, try to explain each abbreviation at first and then use its short form.

Empirical Results:

Results are explained in detail. Must add much more explanations and interpretations for the results, which are not enough. It is suggested to compare the results of the present research with some similar studies which is done before (more justification is needed).

Future Directions:

Please revise your future research and limitation part into more detail. It would be best if you enhanced your this section.

I hope these comments would enhance the quality of the manuscript to make it an appropriate fit for the Journal readership.

Reviewer #2: Please include the following items when submitting your revised manuscript

1. In order to establish the significance and value of the study, it is necessary to provide a comprehensive rationale for the research, which emphasizes its relevance and unique contributions to the current scholarly discourse. This will strengthen the study's originality and scholarly impact.

2. English check/editing: I found minor typos/ grammatical, this study was presented with depraved English language usage.

3. The conclusion is sufficiently discussed with some useful policy implications. However, limitations and future directions of research should have a reasonably sized paragraph.
