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年版次国家与国际耦合（SIC）多区域投入产出表（Multiregional Input-Output, MRIO），覆盖30个产业部门、中国30个省份以及66个国家与经济体。本研究采用宏观汇总数据、微观结构数据与大语言模型（Large Language Models, LLMs）构建了该SIC方法。该SIC MRIO可刻画国际与次国家经济流动间的交互关系，反映出全球格局下生产与消费网络日益凸显的二元结构特征。
