流通业发展、国内市场一体化与国家价值链分工深化

在加快构建新发展格局的现实背景下,充分发挥超大规模市场优势,推进国家价值链分工深化,对于夯实国内大循环基础、深化内外双循环互促具有重要意义。文章聚焦流通业发展对国家价值链分工深化的影响,以及国内市场一体化所发挥的互补性作用。研究发现：(1)流通业发展将显著推动国家价值链分工深化,并且这一积极作用主要通过流通业规模提升、结构优化、基础设施改善实现。(2)门限回归结果表明,只有当国内市场一体化达到一定水平时,流通业发展促进国家价值链分工深化的积极作用才能显现。(3)异质性检验结果提示,在非劳动密集型行业与中西部地区中,流通业发展对国家价值链分工的正向影响更为明显。未来,应进一步推动流通业的高质量发展,逐步破除国内市场运行过程中的体制机制障碍,促进全国统一大市场形成,为国家价值链的构建奠定基础。

Development of Circulation Industry,Domestic Market Integration and Deepening of the National Value Chain Division#br#

Under the realistic background of accelerating the construction of a new development pattern, to give full play to ultra-large-scale market advantage and deepen the National Value Chain division are significant to consolidate the foundation of the domestic circulation and reinforce the mutual promotion of domestic and international dual circulation. This paper focuses on the impact of the development of circulation industry on the National Value Chain division and the complementary role played by the domestic market integration. The paper finds that: (1) the development of circulation industry will significantly promote the deepening of the National Value Chain division. This positive effect is mainly realized through scale expansion, structure optimization and infrastructure improvement of circulation industry. (2) Threshold regression results show that only when the domestic market integration reaches a certain level can the development of circulation industry play a positive role in promoting the deepening of the National Value Chain division. (3) Further heterogeneity tests suggest that in non-labor-intensive industries and the central and western regions, the development of circulation industry has a more significant positive impact on the National Value Chain. In the future, we should further promote the high-quality development of the circulation industry, and gradually remove the institutional obstacles in the domestic market, in order to promote the formation of the national unified market, and lay a foundation for the construction of National Value Chain.
