数字化转型对制造业出口竞争力影响研究——基于细分行业视角
Research on the Impact of Digital Transformation on the Export Competitiveness of Manufacturing Industry—Based on the Perspective of Subdivision Industry

新发展格局背景下，积极推动制造业数字化转型进程已成为塑造国际竞争市场新优势的核心要点。本研究选取2012年至2021年中国制造业的14个行业作为研究样本，探究数字化转型对制造业出口竞争力的影响及其作用机制。通过实证分析，本文揭示了数字化转型与制造业出口竞争力之间存在的显著关系，并对其内在机制进行深入剖析。研究结果表明，本文所探讨的数字化转型指数与出口竞争力之间呈现出显著的正相关性。数字化转型在提升制造业出口竞争力方面发挥了积极的推动作用，存在技术水平不等及要素密集度差异的行业异质性，通过机制检验分析得知，数字化转型通过成本节约效应、技术创新效应提升制造业出口竞争力。据此，提出加强数字基础设施和平台建设，注重数字化技术创新环境建设，针对行业实施差异化战略，加快推进数字产业化、产业数字化发展等对策建议，以期对我国制造业出口竞争力提升进一步赋能。
Under the background of the new development pattern, actively advancing the process of digital transformation within the manufacturing sector has become the core point to shape new advantages in the international competitive market. This study selects 14 sub-sectors of China’s manufacturing industry from 2012 to 2021 as samples, seeking to investigate the influence and underlying mechanisms of digital transformation on the export competitiveness of the manufacturing sector through empirical methods. Utilizing empirical analysis, the research uncovers a notable relationship between digital transformation and the export competitiveness of manufacturing, as well as its underlying mechanisms. The findings indicate a notable positive association between the dependent variable NRCA and the primary independent variable, which is the digital transformation index, discussed in this paper. In other words, the digital transformation of the manufacturing sector serves as a catalyst for enhancing the export competitiveness of manufacturing. There is industry heterogeneity in terms of unequal technological levels and differences in factor intensity. Through mechanism testing analysis, it is known that digital transformation promotes the improvement of manufacturing export competitiveness through cost savings and technological innovation effects. Based on this, it is proposed to strengthen the construction of digital infrastructure and platforms, focus on the construction of digital technology environment, implement differentiated strategies for industries, accelerate the development of digital industrialization and industrial digitalization, along with various other countermeasures and recommendations, aimed at further bolstering the export competitiveness of China’s manufacturing sector.
