ADB MRIO Panel Data (2000-2023) for adbmrio R Package
收藏资源简介：
This dataset provides a pre-processed, harmonized panel of the Asian Development Bank (ADB) Multi-Regional Input–Output (MRIO) tables. It integrates historical MRIO releases and the more recent environmentally extended tables into a single, consistent R list object, suitable for time-series analysis of production, trade, and global value chain (GVC) linkages. All values are expressed in constant prices. The panel covers 63 economies and 35 sectors, with a uniform sectoral classification and matrix dimension across time. Temporal Coverage The panel contains 17 benchmark years within the 2000–2023 period: Available years: 2000, 2007, 2008, 2009, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 Non-available years: 2001–2006, 2010 Key Features Harmonized time series. Variables, country coverage, sector coverage, and matrix dimensions are standardized across all 17 years. Environmental extension. 2017–2023. Includes ADB’s Environmentally Extended Multiregional Input–Output Tables (EE-MRIOTs) with CO₂ emissions in both level form (CO2_raw) and intensity coefficients (CO2_coeff, CO2_diag). 2000–2016. Emission-related variables are zero-valued placeholder matrices. This design preserves a stable data structure so that code using emissions can run without modification while returning zeros for environmental indicators in earlier years. Efficient storage. The dataset is stored as a compressed .rds file using sparse matrix formats to support large-scale linear algebra operations in R. Intended Use The panel is designed as the core input for the adbmrio R package and for MRIO-based research on trade, production linkages, and GVC participation. Its structure is compatible with bilateral trade decomposition and GVC analysis following, for example, Zhang et al. (2017) and related frameworks.
