A multi-regional input-output database linking Chinese subnational regions and global economies

In this database, we develop a subnational and international coupling (SIC) MRIO in 2017, covering 30 sectors, 30 provinces in China and 66 countries & economies. We employ macro-level aggregated data, micro-level structural data and large language models (LLMs) to construct the SIC method. Our SIC MRIO captures the interplay between international and subnational economic flows, reflecting the emerging dual structure of production and consumption networks in the global landscape.

本数据库构建了2017年版国内区域与国际耦合（subnational and international coupling, SIC）多区域投入产出（MRIO）模型，涵盖30个产业部门、中国30个省份以及66个国家与地区。我们采用宏观加总数据、微观结构数据以及大语言模型（LLMs）构建了该SIC方法体系。该模型能够刻画国际与国内区域间经济流动的相互作用机制，反映出全球格局下生产与消费网络逐步形成的二元结构特征。
