十九大报告提出，我国经济已由高速增长转向高质量发展阶段，现阶段推进经济高质量发展是工作的重点内容。黄河作为我国第二长河，横跨东中西部，流域途径九省区。黄河流域丰富的资源储量对于经济发展具有重要作用，同时流域环境也是维护生物多样性的重要生态场所，但过去粗放式发展的模式不仅严重阻碍了流域内省区经济的健康发展，也加剧了生态的不稳定性。数字经济作为一种全新经济模式，既能给发展提供新动力，又是革命性创新的新阵地，在我国“十四五”规划中也提出明确发展数字经济的具体规划。本文拟通过研究2011—2020年黄河流域这个具体区域下数字经济对经济高质量发展的影响，为未来更充分利用数字经济实现经济高质量发展提供建议。

首先，从国内外文献入手，掌握对经济高质量发展内涵的研究现状，梳理数字经济发展脉络，说明本文主要变量的内涵界定与测度方法，根据理论基础提出数字经济从企业、劳动者、产业和社会四大视角对黄河流域经济高质量发展的影响路径；其次，构建数字经济发展指标体系，用熵值法测算；之后，从教育、政府、投资、交通四个方面引入控制变量，通过固定效应下空间杜宾模型讨论数字经济对黄河流域经济高质量发展产生的空间效应，并进行稳健性检验；最后，得出相关结论与发展建议。

研究发现：第一，数字经济发展水平与黄河流域经济高质量发展水平整体向好，但流域内省区发展不均衡、差异大。第二，黄河流域经济高质量发展水平存在明显空间溢出效应。第三，数字经济对经济高质量发展正向空间溢出效应显著，对效应进行分解后结论依然成立。第四，教育、政府、投资与交通四个方面的提升都有利于经济高质量水平的发展。但交通基础设施水平的长期间接效应为负。

The report of the 19th National People's Congress proposed that China's economy has switched from the high growth stage to the high quality development period, and advancing the high quality development of the economy at this phase is a major part of the task.As the second longest river in China, the Yellow River spans the eastern, central, and western regions, and its drainage area passes through nine provinces . The rich resource reserves in the Yellow River basin play an important role in economic development, and the environment in the basin is also an important ecological site for maintaining biodiversity. However, the past extensive development model not only seriously hindered the healthy development of the provincial economy in the basin, but also exacerbated the ecological instability. As a new economic model, the digital economy can not only provide new impetus for development, but also provide a new front for revolutionary innovation. In China's "14th Five Year Plan", specific plans for the development of the digital economy have also been proposed.This paper intends to study the impact of the digital economy on the high quality economic development under the particular region of the Yellow River Basin from 2011 to 2020, and provide suggestions for making fuller use of the digital economy to achieve high quality economic development in the future.

First, starting from domestic and international literature, we will grasp the current status of research on the connotation of high-quality economic development, sort out the development of digital economy, describe the connotation and measurement methods of the main variables in this paper, and propose the impact path of digital economy on the high-quality economic development of the Yellow River Basin from the four perspectives of enterprises, workers, industries and society based on the theoretical basis; Secondly, construct an indicator system for the development of the digital economy, using the entropy method to calculate; After that, control variables were introduced from four aspects: education, government, investment, and transportation. The spatial effects of digital economy on high-quality economic development in the Yellow River Basin were studied using a fixed effect spatial Dubin model, and the robustness was tested; Finally, draw relevant conclusions and development recommendations.

The study found that: first, the overall development level of digital economy and the quality development level of the Yellow River Basin economy is good, but the uneven development and differences between provinces and regions in the basin. Secondly, there is a distinct space spillover effect on the level of economic quality development in the Yellow River Basin. Thirdly, the effect of digital economy on the positive space spillover of high quality economic development is remarkable, and the conclusion still holds after the decomposition of the effect.Fourth, improvements in education, government, investment, and transportation are all conducive to high-quality economic development. However, the long-term indirect effect of transportation infrastructure level is negative.
