      目前我国经济进入新常态，转变经济发展方式势在必行。甘肃省是我国西部欠发达省份，经济发展水平相对滞后，因此在新发展新阶段亟待新经济形态的驱动，而作为信息技术迭代发展的一种新兴经济形态，数字经济能够不断为经济赋能并注入活力，成为推动高质量发展的新引擎。有鉴于此，分析数字经济对甘肃省高质量发展水平的影响，对建设幸福美好新甘肃具有重要指导意义和借鉴价值。
      本研究在梳理数字经济与高质量发展相关文献、理论及影响机制的基础上，基于甘肃省2003-2021年14个市州的面板数据，采用熵值法，测算出数字经济和高质量发展的综合指数，分析二者的发展水平和区域差异，并运用相关模型与方法，实证研究甘肃省数字经济对高质量发展的影响机制和效应，结果表明：（1）甘肃省数字经济发展水平整体上呈上升趋势，但各市州数字经济发展差距较大，始终处于较高水准的是兰州市和嘉峪关市，发展指数均值位于全省前列；而定西市、陇南市指数均值处于末位。（2）甘肃省在稳中向好的过程中实现高质量发展，发展水平最高的是省会城市，而水平较低的多为资源枯竭型城市和少数民族人口占比较高的城市；甘肃省高质量发展水平未来转移趋势较小，等级跃迁的概率较低且多为向上转移；高质量发展水平的区域差异总体上表现为稳步下降态势，区域间差异是导致整体发展水平差异的最重要因素。（3）从直接效应来看，数字经济对甘肃省高质量发展具有显著推动作用；政府干预程度越大，区域高质量发展状况越差；金融发展水平和人力资本水平越高，区域高质量发展状况越好。（4）从传导机制来看，数字经济能够通过促进产业结构升级、实行积极老龄化两条路径实现甘肃省的高质量发展。（5）从门槛效应来看，随着甘肃省数字经济水平的提高，其对地区高质量发展水平的显著促进作用则呈现出边际效应递增的非线性特征。（6）从区域异质性来看，按高质量发展水平划分，数字经济对甘肃省明星型城市、平庸型城市和落后型城市高质量发展的边际贡献依次递减；按地域划分，数字经济对陇中地区、河西地区、陇东地区、陇南地区和甘南地区高质量发展的影响系数分别为0.393、0.456、0.146、0.411、0.203，除陇东地区影响程度最小且不显著外，其余地区系数都在1％水平下显著为正。
      基于上述结论，本研究提出以下建议：一是发展数字经济，赋能甘肃省实现高质量发展；二是加大传统产业数字化转型，推动产业结构优化升级；三是助推“积极老龄化”，实行“数字适老化”；四是制定差异化区域发展战略，推动区域协调发展；五是打造数字政府协同治理模式，加快甘肃省政府治理现代化建设。

The economic growth of Gansu Province, a less developed region in the western part of China, is lagging behind, thus necessitating a shift in the way China's economy is progressing. To achieve this, the new economic form - digital economy - must be driven by the iterative development of information technology, and it can continue to energize and empower the economy, thus becoming a powerful engine for high-quality development. This is especially true as the country has recently reached a new equilibrium. In view of this, the significance and value of assessing the effect of the digital economy on the quality of development in Gansu Province is immense, and this is essential for constructing a blissful and exquisite new Gansu.

By analyzing the panel data of 14 cities and states in Gansu Province from 2003 to 2021, this research was conducted to explore the relevant research literature, theories, and influence mechanisms of digital economy and high-quality development，combined with regional characteristics, uses the entropy value method to Measure a composite index system of digital economy and high-quality development, analyzes the level of development of the two and the regional differences, and empirically researches the digital economy in Gansu Province by using the relevant models and methods. Influence mechanism and effect on high-quality development, the results of the study show that: (1) Gansu Province digital economy development level on the whole shows an upward trend, but the gap between the development of the digital economy in various cities and states is large, always at a higher level is Lanzhou City and Jiayuguan City, the average value of the development index is located in the forefront of the province, and the average value of the index of Dingxi City and Longnan City is in the last place. (2) Gansu Province is gradually stabilizing in order to attain high-grade development, with the capital city at the peak and cities with a greater proportion of ethnic minorities at the lower end. The potential for Gansu Province's high-grade development to alter the trend of small growth is low and mostly upward; however, regional disparities in the level of high-grade development generally demonstrate a steady decline, with inter-regional disparities being the most influential factor in the overall development level. (3)From a direct impact standpoint, the digital economy has a major influence in fostering high-caliber growth in Gansu Province. The more government interference, the poorer the regional quality of development. The regional high-quality development status is enhanced by a greater degree of financial and human capital development. (4) From a transmission mechanism standpoint, Gansu Province's high-quality development can be achieved through two avenues: augmenting industrial structure and Implementing active aging through digital economy.(5) As the digital economy of Gansu Province rises, its considerable contribution to regional high-quality growth is demonstrated by a non-linear trend of augmenting marginal effect, from the point of view of threshold effect. (6) From the point of view of regional heterogeneity, according to the division of the level of high-quality development, the marginal contribution of the digital economy to the high-quality development of star-type cities, mediocre cities and backward cities in Gansu Province decreases in turn; according to the geographic division of the digital economy on the high-quality development of Longzhong region, Hexi region, Longdong region, Longnan region and Gannan region, the coefficients of the impact of the digital economy on the high-quality development of the Longzhong region, respectively, are 0.393, 0.456, 0.146, 0.411, 0.203, in addition to the Longdong region has the smallest degree of influence and is not significant, the coefficients of the rest of the region are significantly positive at the 1% level.

This study proposes five recommendations: first, to empower Gansu Province for high-quality development, the digital economy should be developed; second, traditional industries should be digitally transformed to optimize and upgrade their industrial structure; third, to promote “active aging” and implement “digital aging”;fourth, a differentiated regional development strategy should be formulated to promote coordinated growth in the region; and fifth, a collaborative governance model of the digital government should be established to expedite modernization of Gansu Province's government governance.
