数字经济对贵州省高质量发展影响研究

Research on the Impact of Digital Economy on the High-Quality Development of Guizhou Province

摘要: 数字经济已成为推动区域高质量发展的重要动力。本文基于2015~2023年贵州省9个地州市面板数据，采用改进后的熵权法构建数字经济与高质量发展评价体系，并使用双固定效应模型实证分析其作用机制。研究发现：(1) 数字经济显著地促进了贵州省高质量发展，该研究结论经过核心变量替换、控制变量增加及删减年份调整等稳健性检验后依然有作用；(2) 技术进步是核心中介路径——数字经济通过降低创新成本、加速知识溢出，推动产业结构升级与全要素生产率提升，进而加强了高质量发展；(3) 异质性分析可以看出，数字经济对智慧试点城市的高质量发展正向影响显著，对非智慧试点城市高质量发展正向影响不显著；数字经济对高人力资本水平的城市高质量发展发挥促进作用，对低人力资本水平高质量发展影响不显著；该研究成果为西部地区数字经济政策优化与区域协调发展提供有效的理论参考与实践启示。

Abstract: The digital economy has become an important driving force for promoting high-quality regional development. Based on the panel data of 9 prefecture-level cities in Guizhou Province from 2015 to 2023, this paper constructs an evaluation system for the digital economy and high-quality development by using the improved entropy weight method, and empirically analyzes its mechanism through a double fixed-effect model. The research findings are as follows: (1) The digital economy has significantly promoted the high-quality development of Guizhou. This conclusion remains valid after a series of robustness tests, including variable substitution, control variable addition and deletion, and year adjustment. (2) Technological progress is the core mediating path; the digital economy promotes high-quality development by reducing innovation costs, accelerating knowledge spillovers, promoting industrial structure upgrading and total factor productivity improvement. (3) Heterogeneity analysis shows that the digital economy has a significant positive impact on the high-quality development of smart pilot cities, but has no significant positive impact on the high-quality development of non-smart pilot cities. The digital economy promotes the high-quality development of cities with high human capital levels, but has no significant impact on the high-quality development of cities with low human capital levels. It provides effective theoretical reference and practical inspiration for optimizing digital economy policies and promoting regional coordinated development in the western region.
