科技创新是经济高质量发展的核心驱动力。本文基于2011年~2024年无锡市的时间序列数据， 运用固定效应模型、中介效应模型与调节效应模型，实证检验了科技创新对经济高质量发展的影响效 应与作用机制。研究结果表明：数字经济显著提升经济发展水平。其影响机理表现为：科技创新主要 通过加强人力资本累积、推动产业结构升级促进经济高质量发展，并且环境规制正向调节两者之间的 关系。基于此，提出强化科技创新投入、深化产业结构以及优化环境规制等建议，以期进一步提升无 锡市经济发展水平。

Technological innovation (TI) is the driving high-quality economic development. Based on time-series data of Wuxi from 2011 to 2024, this paper employs fixed effects, mediation, and moderation models to examine the mechanisms. The results show that TI significantly enhances economic development. Mechanistically, TI promotes high-quality economic development by strengthening human capital accumulation and upgrading industrial structure. Additionally, environmental regulation positively moderates this relationship. Therefore, this paper proposes policy recommendations, including strengthening investment, upgrading industrial structure, and optimizing the environmental regulation.
