摘要:

当前,数字产业集群的建设为提升制造业的国际竞争力提供了重要的机遇和动力。本文基于2012—2021年中国30个省份的面板数据,系统地探讨了数字产业的专业化集聚和多样化集聚对制造业出口技术复杂度的影响及其作用机制。研究结果表明,无论是专业化集聚还是多样化集聚,都对提高制造业出口技术复杂度产生了显著的正向效应。在控制了不同变量、替换了解释变量以及缓解内生性问题后,这些结果依然稳健。此外,不同地区和行业之间的效应表现出一定的异质性。进一步探究其作用机制发现,数字产业的专业化集聚主要通过吸引外资和降低交易成本来提升出口技术复杂度;而多样化集聚则通过技术溢出和降低交易成本对出口技术复杂度产生影响。门槛效应分析进一步揭示,在较高的城镇化水平和技术密集的环境下,专业化集聚对技术复杂度的提升效果更为显著。本文的实证研究为制定因地制宜的数字产业发展政策提供了实证依据,强调应根据不同地区和行业的特点推进数字产业集群建设,从而为制造业的高质量发展提供有力支持。

Abstract:

The development of digital industry clusters currently offers significant opportunities and momentum for enhancing the international competitiveness of the manufacturing sector. This study employs panel data from 30 Chinese provinces covering the period from 2012 to 2021 to systematically investigate the impact and mechanisms of specialized and diversified digital industry clusters on the technological complexity of manufacturing exports. The findings reveal that specialized and diversified clusters positively and significantly enhance the technological complexity of manufacturing exports. These results remain robust even after controlling for variables, replacing dependent variables, and addressing endogeneity issues. Moreover, the effects vary across different regions and industries. Specifically, specialized clustering in the digital industry enhances the technological complexity of exports primarily by attracting foreign direct investment (FDI) and reducing transaction costs, whereas diversified clustering achieves this through technological spillovers and transaction cost reduction. Threshold effect analysis further indicates that in regions with higher levels of urbanization and technological intensity, the impact of specialized clustering on technological complexity is more pronounced. This empirical study provides evidence-based support for the formulation of tailored digital industry development policies, highlighting the need to promote digital industry clusters according to the unique characteristics of different regions and industries, thereby facilitating the high-quality development of the manufacturing sector.
