Xu, Z., Li, Y., Chau, S.N. et al. Impacts of international trade on global sustainable development. Nat Sustain 3, 964–971 (2020)

Objective:

  • Little research quantitatively assesses multiple aspects of SDGs simultaneously at the global scale
  • Compre international trade between adjacent countries

Case:

  • Global countries

Methodology:

  • The monetary output $m$ of sector $i$ in $m$ country $R$:
    • $x_i^R = \sum_{Q=1}^m \sum_{j=1}^n x_{ij}^{RQ} +\sum_{Q=1}^m y_i^{RQ}$, where $Q$ is also the original country. $y_i^{RQ}$ is the final demand.
  • Direct input coefficient $a_{ij}^{RQ}$
    • $a_{ij}^{RQ} = x_{ij}^{RQ} / x_j^Q$
  • Let $X = [X_i^R]$, $A = [a_{ij}^{RQ}]$, and $Y = Y_i^{RQ}$
    • $X = A \times X + Y$
    • $X = B \times Y$, $B = (I-A)^{-1}$, where $(I-A)^{-1}$ is the Leontief inverse matrix
  • Embeded resource:
    • $e_i^R = w_i^R / x_i^R$, where $w_i^R$ is the total resource / material intensity, $e_i^R$ is the amount of resource / material consumed or emitted to increase one monetary unit of output
  • Virtual resource:
    • $VR = E \times B \times Y$

Findings:

  • Global trend and spatial pattern of progress towards multiple SDGs goals
  • International trade improved the global SDG score and positively affected progress towards achieving all nine SDG targets at the global level
  • Different impacts across countries
  • With trade, progress towards achieving the SDG targets improved in most developed countries but decline in most developing countries
  • The SDG target scores of developed countries were higher than those of developing countries with international trade; but they would be lower than those of developing countries without trade
  • Distant trade contributed more towards achieving the evaluated SDG targets than did adjacent trade
