摘要: 国内市场互联互通是畅通国内大循环的重要内容,从“五统一”视角深入理解国内市场互联互通在提升省际贸易福利方面的作用,对于建设强大国内市场具有深远意义。通过构建非对称的多阶段一般均衡模型,量化国内市场互联互通对省际贸易福利的影响,并对其生产特征进行空间解构。研究表明:国内市场互联互通总体上显著促进了省际贸易强度的提高,但要素资源互联互通的促进作用仍有较大的提升空间;国内市场互联互通提升了省际贸易福利,其中,商品服务互联互通对贸易福利的提升效果最为显著,其次为交通设施、市场制度、要素资源与市场监管;国内市场互联互通对东部以及东北地区的贸易福利平均提升幅度要高于中西部地区,在多阶段生产模式下,全国整体的贸易福利平均提升幅度要显著高于迂回生产。地方政府应结合实际情况积极响应“五统一”举措,以省际合作促进区域协调发展,以多阶段生产模式充分释放地区比较优势,从而助力畅通国内大循环发展目标的实现,并为增进国内市场互联互通与提升省际贸易福利提供实践经验。

Abstract: Domestic market connectivity is an important element of unimpeded domestic circulation, and an in-depth understanding of the role of domestic market connectivity in enhancing the welfare of inter-provincial trade from the perspective of the“five unities”is of far-reaching significance to the construction of a strong domestic market. By constructing an asymmetric multi-stage general equilibrium model, this study quantifies the impact of domestic market connectivity on the welfare enhancement of inter-provincial trade, and spatially deconstructs its production characteristics. The findings show that domestic market connectivity in general significantly promotes the growth of inter-provincial trade intensity, but there is still much room for improvement in the promotion of factor resource connectivity. Domestic market connectivity has enhanced the inter-provincial trade welfare, among which the interconnection of goods and services has the most significant effect on improving trade welfare, followed by transportation facilities, market systems, factor resources, and market supervision. The average increase in trade welfare for the eastern and northeastern regions is higher than that for the central and western regions due to the inter-connectivity of the domestic market. Under the multi-stage production mode, the overall average increase in trade welfare for the country is significantly higher than that of indirect production. Local governments should respond positively to the “five unities”initiative in light of the actual situation, promote the coordinated regional development through inter-provincial cooperation, and fully release regional comparative advantages through multi-stage production, so as to help achieve the goal of smooth and greater domestic circulation development and provide practical experience for domestic market connectivity and inter-provincial trade welfare enhancement.

Key words: domestic market, five unities, market connectivity, inter-provincial trade welfare
