数字经济引领经济高质量发展日益凸显，我国数字经济发展迈入世界前列的事实备受国际社会的广泛关注，也成为发达国家的忧患。成渝地区双城经济圈作为我国经济高质量发展的重要增长极和动力源，肩负着数字经济引擎之使命。基于2014-2019年成渝地区双城经济圈内16个地级城市的面板数据，结合成渝双城经济圈数字经济和经济高质量发展现状，分别测度及评价二者发展水平，进一步运用灰色关联分析法，构建二者耦合协调测度模型进行实证分析。结果表明:（1）成渝经济圈数字经济与经济高质量发展耦合协调度偏低，数字经济发展水平还不能与经济高质量发展相协调，数字经济对于经济高质量发展水平的贡献程度较低；（2）经济圈的二者耦合协调度总体呈上升态势，显示数字经济推动经济高质量发展的作用和贡献逐渐增强；（3）经济圈各城市的二者耦合协调程度不同，各城市数字经济推动经济高质量发展的贡献程度不一，形成不协调发展态势。据此提出成渝经济圈数字经济推动经济高质量发展的政策建议。

It is increasingly prominent that the digital economy leads the high-quality development of the economy. The fact that the development of my country's digital economy has entered the forefront of the world has attracted extensive attention from the international community and has become a worry for developed countries. As an important growth pole and power source for my country's high-quality economic development, the Chengdu-Chongqing Economic Circle shoulders the mission of the engine of the digital economy. Based on the panel data of 16 prefecture-level cities in the Chengdu-Chongqing economic circle from 2014 to 2019, combined with the current situation of digital economy and high-quality economic development in the Chengdu-Chongqing economic circle, the development levels of the two were measured and evaluated respectively, and the gray scale was further used. Correlation analysis method was used to construct a coupling coordination measurement model of the two for empirical analysis. The results show that: (1) The degree of coupling coordination between digital economy and high-quality economic development in the Chengdu-Chongqing Economic Circle is low, the level of digital economy development cannot be coordinated with high-quality economic development, and the contribution of digital economy to high-quality economic development is low. (2) The degree of coupling and coordination of the two in the economic circle is generally on the rise, indicating that the role and contribution of the digital economy in promoting high-quality economic development is gradually increasing; (3) The degree of coupling and coordination between the two in each city in the economic circle is different, and the number of cities in each city is increasing. The contribution of the economy to promoting high-quality economic development varies, resulting in an uncoordinated development trend. Based on this, policy recommendations for the digital economy of the Chengdu-Chongqing Economic Circle to promote high-quality economic development are put forward.
