全要素生产率提升是衡量新质生产力发展的核心标志。本研究在理论阐释全国统一大市场、数据要素利用与制造业全要素生产率之间关系的基础上，选取2014—2023年中国省级面板数据，实证研究全国统一大市场对制造业全要素生产率的影响及其作用机制。结果表明，全国统一大市场对制造业全要素生产率增长具有显著正向影响。作用机制分析结果显示，降低交易成本是全国统一大市场促进制造业全要素生产率增长的重要渠道。异质性分析结果显示，全国统一大市场对东部地区以及资本和技术密集型制造业的全要素生产率具有更强的促进作用。进一步的扩展性分析结果表明，数据要素利用能够显著增强全国统一大市场对制造业全要素生产率的促进效应。本研究结论可以为加快推进数据要素市场化配置提供理论依据；为构建全国统一市场，实现制造业全要素生产率提升，助力经济高质量发展提供决策参考。

The improvement of total factor productivity is the core indicator of new quality productivity.On the basis of the theoretical explanation of the relationship between the unified national market, data elements and total factor productivity of manufacturing industry, this study selects the provincial panel data of China from 2014 to 2023 to empirically study the impact of the national unified market on the total factor productivity of the manufacturing industry and its mechanism of action. The results show that the unified national market has a significant positive impact on the total factor productivity growth in manufacturing industry. The analysis of the mechanism of action shows that reducing transaction costs is an important channel for the unified national market to promote the total factor productivity growth in manufacturing industry. The heterogeneity analysis results show that the unified national market has a stronger promoting effect on the total factor productivity in manufacturing industry in the eastern region and in capital and technology-intensive manufacturing industries. The further extended analysis results show that the utilization of data elements can significantly enhance the promoting effect of the unified national market on the total factor productivity in manufacturing industry. The research conclusions can provide a theoretical basis for accelerating the market-based allocation of data elements. The research conclusions also provide decision-making reference for building a unified national market, achieving the improvement of the total factor productivity in manufacturing industry, and promoting high-quality economic development.
