China's Provincial Multi-Regional Input-Output Database for 2018 and 2020.

Area of Science:

• Economics
• Environmental Science
• Regional Science

Background:

• The U.S.-China trade friction (2018) and COVID-19 pandemic (2020) significantly disrupted China's domestic supply chains.
• Existing multi-regional input-output (MRIO) models lack data to analyze these specific disruptions on regional supply chains.
• Understanding economic linkages and environmental impacts requires accurate, up-to-date supply chain data.

Purpose of the Study:

• To construct Chinese multi-regional input-output (MRIO) tables for 2018 and 2020.
• To address the data gap concerning the impacts of trade friction and the pandemic on regional supply chains.
• To provide insights into the adaptation of regional supply chains and economic structures.

Main Methods:

• Utilized hybrid methods to construct Chinese MRIO tables for 2018 and 2020.
• Covered 31 regions and 42 sectors within the Chinese economy.
• Ensured dataset consistency with previous MRIO models for 2012, 2015, and 2017.

Main Results:

• Developed novel MRIO tables capturing the effects of the trade war and pandemic.
• The dataset allows for detailed analysis of cross-regional spillover effects.
• Identified regional and sectoral variations in supply chain impacts.

Conclusions:

• The constructed MRIO tables fill a critical data gap for analyzing recent economic shocks.
• The findings offer crucial insights into the resilience and adaptation of China's regional economies.
• This work supports future research on economic linkages and environmental consequences.
